Cobalt

Cobalt (pronounced koh-bawlt)

(1) A brittle, hard, lustrous, silvery-white-gray element (a ferromagnetic metal) which is found principally in cobaltite and smaltite and is widely used in (1) the rendering of both heat-resistant and magnetic alloys, (2) in clinical oncology and (3) as a blue pigment used to color ceramics, glass and other materials.

(2) As cobalt blue, a deep blue pigment derived from cobalt; zaffre.

(3) As cobalt therapy (known colloquially as the “cobalt ray”), a gamma ray treatment first used in the early 1950s in clinical oncology executed with external beam radiotherapy (teletherapy) machines using the radioisotope cobalt-60 with a half-life of 5.3 years.

1675–1685: From the German Kobalt & Kobold (a variant of Koboldkobold), from the Middle High German kobolt (household goblin), the name derived from the belief held by silver miners in the Harz Mountains that malicious goblins placed it in the silver ore, based on the rocks laced with arsenic and sulfur which degraded the ore and caused illness.  The construct was the Middle High German kobe (hut, shed) + holt (goblin) from hold (gracious, friendly), a euphemistic word for a troublesome being, designed to avoid offending the creature and thus inviting retribution.  It thus became part of German folk culture as an earth-elemental or nature spirit.  Although much rarer, the metallic element closely resembles nickel and was documented by but much rarer) was extracted from this rock. It was mentioned in the alchemy notes of Paracelsus (the Swiss physician, alchemist, lay theologian, and philosopher of the German Renaissance Theophrastus von Hohenheim (circa 1493-1541)), but as an element its discovery is credited to the Swedish chemist and mineralogist Georg Brandt (1694–1768) who in 1733 gave it the name.  Although it has since the mid-sixteenth century been used as a coloring agent for glass and ceramics, “cobalt blue” didn’t come into formal use until 1835.  There is also cobalt green (A variety of green inorganic pigments obtained by doping a certain cobalt oxide into colorless host oxides.  Cobalt & cobaltite are nouns and cobaltic, colbaltous & colbaltesque are adjectives; the noun plural is cobalts.

Currently, most of the world's cobalt is supplied by mines in the Democratic Republic of Congo (the DRC, the old Republic of Zaire (1971-1997)) which account for some 60% of annual production.  Because of (1) industry economics and (2) the natural geological occurrence of the minerals, cobalt typically is extracted as a by-product of copper or nickel mining operations.  Smaller-scale mining is also undertaken in Canada, Australia, Russia and the Philippines.

In the early days of motorsport, cars were painted in accord with their country of origin (the corporate liveries reflecting the source of the sponsorship didn’t reach all categories until the late 1960s) and the French chose blue.  Originally it was the exact shade used on the tricolore (the national flag) but teams soon adopted various shades.  The British were allocated green which became famous as the dark shade used on the Bentleys which raced at Le Mans in the 1920s but it too was never exactly defined and over the decades lighter and darker hues were seen.  The Italians of course raced in the red best represented by Ferrari’s Rosso Corsa (Racing Red) although in the era red at least once appeared on the bodywork of the car of another nation.  The winner of the 1924 Targa Florio in Sicily was a bright red Mercedes Tipo Indy and, being German, should have been painted in their racing color of white but, noting the rocks and other items the Italian crowd was inclined to throw at any machine not finished in Rosso Corsa, the team decided subterfuge was justified and the use of white by German entrants anyway didn’t last even a decade after the victory.

In 1934, with the Mercedes-Benz and Auto Union factory teams supported by the Nazi state as a propaganda project, the Mercedes-Benz W25s appeared in silver, the bare aluminum polished rather than painted.  For decades, the story told was that after a practice session, upon being weighed, the cars were found to be a kilogram-odd over the 750 KG limit for the event and the team had to work overnight to scrape off all the carefully applied, thick white paint, the weigh-in on the morning of the race yielding a compliant 749.9.  It was a romantic tale but has since been debunked, the race in question not being run under the 750 KG rule and in the 1990s, a trove of photographs was uncovered in an archive showing the cars arriving at the track unpainted, already in bare silver.  The authorities did request the Mercedes-Benz and Auto Union teams revert to white but already motorsport’s prime directive of the 1930s was operative: "Give way to the Germans".  That race in 1934 was the debut of the “silver arrows” but it happened not quite as the legend suggested.  Even the factory now refers to the tale as "the legend".

The International Organization for Standardization (ISO) has issued standard (ISO 11664-3:2019) which defines the technical terms and the colorimetric equations necessary for colorimetry and in that cobalt blue has been defined as Hex triplet #0047AB; sRGBB (r:0; g:71; b:171) & HSV (h: 215°; s: 100%; v:67%).  However, among manufacturers it’s often just a vague descriptor on the color chart and like many colors is treated as a spectrum with hues varying in shade and tone.  In the fashion industry there’s no attempt whatever at standardization or even consistency and the same house has been known to describe the fabric used in one range “cobalt blue” while in another line it might be “ultramariine”, “Prussian blue” “royal blue” or anything else which seems to suit.

The cobalt bomb is a speculative nuclear weapon, first suggested in 1950 by one of the leading physicists associated with the Manhattan Project which during World War II (1939-1945) developed the world’s first atomic bombs.  It was the implications of the cobalt bomb which first gave rise to the doomsday notion that it might be possible to build weapons which could kill all people on earth.  The device would be constructed as a thermo-nuclear weapon consisting of a hydrogen (fusion) bomb encased in cobalt which upon detonation releases large quantities of radioactive cobalt-60 into the atmosphere and from the site of the explosion it would be dispersed worldwide by atmospheric processes.  Because of its half-life, were the volume of the release to be sufficient, the entire planet could be affected well before radioactive decay reached the point where human (and almost all animal) life could be sustained.  It’s believed no full-scale cobalt bomb was ever built but the British did test the concept on a tiny scale and few doubt the major nuclear weapons powers have all simulated cobalt bombs in their big computers and, awesome of awful depending on one’s world view, the thing has long been a staple in science fiction and the genre called “nuclear war porn”.

The descendent of the idea was the neutron bomb which, like the cobalt device, relied for its utility on fall-out rather than the initial destructive blast.  The Pentagon-funded work on the first neutron bomb was conducted under the project name “Dove” (which seems a nice touch) and the rationale was that for use in Europe, what was needed was a weapon with a relatively low blast but which produced a nasty but relatively short-lived fallout, the idea being that there would be a high death-rate among an invading army but little physical damage to valuable real estate and infrastructure.

Teal

Teal (pronounced teel)

(1) Any of several species of small dabbling, short-necked freshwater ducks (such as the Eurasian Anas crecca (common teal)), of worldwide distribution and related to the mallard, travelling usually in tight flocks and frequenting ponds, lakes and marshes.

(2) A color, a medium to dark greenish blue, often mixed with traces of azure, beryl, cerulean, cobalt, indigo, navy, royal, sapphire, turquoise & ultramarine, also called teal blue and (rarely) tealturquoise, peacockblue or blueteal.

(3) As TEAl, the abbreviation of triethylaluminium (in organic chemistry, a volatile organometallic compound (Al₂(C₂H₅)₆ or Al₂Et₆) used in various chemical processes and as an ignitor in rockets and jet engines.)

(4) As TEAL, the (historical) initialism of Tasman Empire Airways Limited, the forerunner to Air New Zealand.

(5) A collective descriptor informally adopted to refer to certain nominally independent candidates contesting certain electorates in the 2022 Australian general election.

1275-1375: From Middle English tele (small freshwater duck), probably from the (unrecorded) Old English tǣle and cognate with the Middle Low German tēlink, from the from West Germanic taili, from the West Frisian tjilling (teal) and the Middle Dutch tēling (teal (source of the Modern Dutch taling)).  The Middle Low German tēlink, was from the Proto-Germanic tailijaz, of unknown ultimate origin, with no cognates outside of Germanic.  As the name of a shade of dark greenish-blue resembling the color patterns on the fowl's head and wings, it is attested from 1923 in clothing advertisements, thereby joining the long list of variations of descriptions of the variations in the shades of blue including: blue; Alice blue, aqua, aquamarine, azure, baby blue, beryl, bice, bice blue, blue green, blue violet, blueberry, cadet blue, Cambridge blue, cerulean, cobalt blue, Copenhagen blue, cornflower, cornflower blue, cyan, dark blue, Dodger blue, duck-egg blue, eggshell blue, electric-blue, gentian blue, ice blue, lapis lazuli, light blue, lovat, mazarine, midnight blue, navy, Nile blue, Oxford blue, peacock blue, petrol blue, powder blue, Prussian blue, robin's-egg blue, royal blue, sapphire, saxe blue, slate blue, sky blue, teal, turquoise, ultramarine, Wedgwood blue & zaffre.  Teal is a noun & adjective and tealish is an adjective; the noun plural is teal or (especially collectively), teals.  The spelling teale is obsolete.

Teal’s hexadecimal code is #008080 with RGB values of R: 0, G: 50.2, B: 50.2 and CMYK values of C: 1, M: 0, Y: 0, K:0.5, a hue angle of 180^o, a saturation of 100% and a lightness of 25.1%.  According to the authoritative Canva, for Tibetan monks it was symbolic of the infinity of the sea and sky and for Egyptians, the color of truth and faith.  Discussing the color, Adobe’s editors were almost lyrical, suggesting readers “picture the warm ocean waves in Baja California, made of that color that isn’t quite blue and isn’t quite green.  The water brings in the cool side of summer.”  That’s evocative but the website goes on to note before it was a color it was the name of a bird, “teal” adopted for the blueish-green (or greenish-blue) only in 1917, the reference being to the area around the eye of the Eurasian teal duck.

The artist’s use of a startling tealish blue for the robe is thought a deliberate choice to emphasize Mary's exalted place in Christian theology.  In Christianity, the Visitation of the Blessed Virgin Mary (clipped usually in general use to “the Visitation”), refers to the visit of Mary, the pregnant with Jesus, to Elizabeth, pregnant with John the Baptist, the story told in the Gospel of Luke (1:39–56).  Traditionally, the Christian feast day commemorating this visit appeared in ecclesiastical calendars on 2 July (Western) or 30 March (orthodox) but in some churches in the West it’s now celebrated on 31 May.

Historically, blue pigment was both expensive and rare; while in the natural environment sources of green were, it was difficult for chemists to create dyes and pigments in blue which did not rapidly (and often inconsistently) fade.  In commerce, because both blue and green pigment were needed to make teal, the blend came to be considered a color of elevated status (and thus price).  The special place of blue (in its time Prussian blue was revolutionary) was reprised in the electronic age when the blue LED (light emitting diode) proved an elusive target.  Although a blue LED had been created as early as 1972 (US Patent US3819974 A granted in 1974), the glow was faint because the materials used in the 1960s & 1970s for red & green LEDs (gallium arsenide (GaAs) or gallium phosphide (GaP) lacked the necessary width in bandgap (in physics the energy difference between two allowed ranges of electron energy in a solid).  Not until the early 1990s did researchers find the method of growing high-quality Gallium Nitride (GaN) at scale on sapphire substrates did the blue LED become technically and commercially viable and with it came the white LED (made possible by combining blue light with yellow phosphor).  That gained the researchers the 2014 Nobel Prize in Physics and the white LED has revolutionized illumination (for birth screens and lighting) and achieved massive energy savings worldwide.

The airline TEAL (Tasman Empire Airways Limited) emerged from the Tasman Sea Agreement, an intergovernmental treaty between the Australia, New Zealand and the UK, concluded in London early in 1940.  The purpose of the operation was to provide for the trans-Tasman traffic of passengers, cargo and mail, something which had been disrupted by the outbreak of hostilities in 1939.  In the manner of a number of wartime agreements, the treaty contained a sunset clause which stipulated a termination within three months of the end of the war with Germany but such was the state of post-war civil aviation that arrangements were carried over and pre-war practices did not return to the trans-Tasman route until 1954.  As part of that re-organization, the shareholdings, which previously had been spread between the New Zealand Government (20%), Union Airways (19%), BOAC (38%) and Qantas (23%), were dissolved and the two governments assumed co-ownership until 1961 when both decided to maintain separate national carriers, TEAL and Qantas, the relationship having been strained since the Australians had insisted TEAL order the turboprop Lockheed Electra to maintain fleet standardization with Qantas while the New Zealanders wanted to upgrade to jets.  In 1965, TEAL was re-named Air New Zealand.

Trooping the color: The teal mafia out campaigning in the Wentworth electorate, Australian general election 2022.

The so-called “teal independents” are a number of nominally independent candidates contesting certain electorates in the 2022 Australian general election.  The teal candidates on which there has been much focus are almost all professional women drawn from outside professional politics, contesting nominally “safe” Liberal Party seats in which there’s a higher than average interest in progressive issues, especially climate change.  The use of the color teal is thought an allusion to the mixing of blue and green, blue a reference either to the “blue-blood” demographic profile of the electorates or it being the traditional color associated with conservative politics and green the environmental consciousness which the teals are making a focus of their campaigns.  Former Liberal Party prime-minister John Howard (b 1939; prime-minister 1996-2007) was not impressed by the practice of styling the teals as “independents”, claiming it was misleading given the source of some of their funding and logistical support from entities which would in the US be understood as PACs (political action committees), entities which combined lobbying with activism on specific issues.  Mr Howard suggested the teals were merely “…posing as independents” and were really “…anti-Liberal groupies”, their aim being “…to hurt the Liberal party, not to represent the middle ground of their electorates” adding “They don’t represent disgruntled Liberals.  They represent a group in the community that wants to destroy the Liberal government. It’s as simple as that.”

Flags of the Liberal Party of Australian and Australian Labor Party (ALP).

Mr Howard was right in that the consequences really are simple as that: if a sufficient number of teals are successful, they will hurt the Liberal party and destroy the Liberal-National coalition government but where the teals would differ from the former prime-minister is in not conflating cause with effect.  The teal candidates have well expressed (if not especially detailed) policy objectives and are seeking to destroy the government because they wish to see alternative policies pursued and about that, voters will agree, disagree or remain indifferent.  What attracted most attention however was Mr Howard’s choice of the word “groupies” to refer to the (mostly female) teals, one critic noting an analysis of the composition of the four ministries he formed while prime-minister did suggest he was inclined to appoint women to the “touchy-feely” portfolios dealing with people while the men got the meatier appointments.

That aside, he does have a point about the word “independent” being misleading.  Historically, in Australia, it’s been understood as meaning a candidate for or member of a parliament who is not a member of a political party (within the legally-defined meaning).  That the teals are not but, though not a conventional party, the teal thing is clearly a concept, a movement or something else beyond a mere state of mind and parts of it are a framework providing the candidates with financial and administrative assistance in a more structured way that that of local volunteers.  The teals (not all of whom use the color in their advertising, one in particular running a “pink” campaign) have also been the victims of some ambush marketing, complaining that others were now muddying the waters by sending out teal-colored flyers.  They might have some difficulty in enforcing an exclusivity of right on a color, about the only restriction enforced is on purple which can’t be used in circumstances where it might be confused with something from the Australian Electoral commission which most jealously guards its purple.  Nor is some fluidity of meaning unknown in Australian politics.  During the 1970s and 1980s, in the Victorian Labor Party, although an apparent contradiction in terms, a faction was formed called the “Independents”, a faction self-described by its members as being a faction for those “who disliked factional politics”.  It was novel then and unthinkable now but happened at a time when the Left had been neutralized by federal intervention and the Right was still obsessed with the DLP (the Democratic Labor Party, the even more right-wing Roman-Catholic breakaway which was until the emergence of One Nation the worst form of political excrement to enjoy significant electoral success) and the Cold War.  There was a gap in the market.

Flags of the Australian National Party & the Australian Greens.

Teal as blend of blue and green imparting political meaning works in Australia because the use of the colors red (of the left), blue (of the right) & green (of the greenies) is well understood.  Even the historic association of the National Party with green doesn’t cause confusion.  The National Party (originally the Country Party and briefly in some places the National-Country Party), had always used green to reflect their agrarian origins but adapted well in the 1980s to the emergence of formalized Green parties (which of course chose green for semiotic purposes).  Pragmatists, the Nationals, operating as usual like horse-traders, settled on a slightly darker shade with gold lettering, the traditional Australian sporting livery.  Briefly, the Nationals had flirted with shades of brown, the idea being to convey “the people of the soil” but the idea was quickly abandoned, not because brown was so associated with the Nazis (the Braunes Haus (Brown House)) was their early Munich headquarters and the Surmabteilung (the SA and literally "Storm Detachment" but usually called storm-troopers) were street thugs known as the “brownshirts” because of their uniform) but because brown is such an unappealing colour and difficult for graphic artists to handle.         

Crooked Hillary Clinton (b 1947; US secretary of state 2009-2013) liked teal pantsuits and retained a fondness for the shade, even as the cut of her clothes became more accommodating.

In a diary entry of 2 September, 1953, Winston Churchill’s (1875-1965; UK prime-minister 1940-1945 & 1951-1955) doctor Lord Moran (Charles Wilson, 1882-1977; president of the RCS (Royal College of Physicians) 1941-1949, personal physician to Winston Churchill 1940-1965) noted his patient reporting he had “…curious, elaborate, complicated dreams.  I wake, but when I go to sleep again they go on.  They are too complicated to explain.”  In one, he described dreaming of a woman who sounded she looked damnably like crooked Hillary the larger:  “For instance, last night I dreamt of a large woman of the Eleanor Roosevelt type, and this woman was President of the United States. It was all extremely vivid, but I want to know what it means.”  His ominous premonition of crooked Hillary as POTUS of course didn’t happen but, despite her presence, he did describe his dreams as “enjoyable”.

The origin of red being associated with the politics of radicalism and revolution is generally assumed to date from the use in the French revolution where the idea was to represent the blood spilled in the overthrow of the ancien régime although the shade used should perhaps have been darkened a little in the years that followed as the revolution began “to consume its children”.  Around the planet, colors are widely used as political identifiers and, with different traditions of use and history of origin, there’s a wide divergence of meaning; what a color in one country conveys can mean the opposite in another.  There’s also the point that at one, important level, a color is just a color and the choice, even for political purposes, may be purely on aesthetic grounds:  Hitler made no secret that he choose red, white and black as for the early depictions of the swastika and other Nazi imagery because his ideological opponents, the communists, had used it with such success.  Among the best known color adoptions are orange and green in Ireland, yellow and red in Thailand and black by the so-called Islamic State (داعش, Dāʿish) and a number of Islamist and Islamic fundamentalist movements (as a symbol of jihad), saffron in India because of the traditional association with Hinduism and the Hindu nationalist movement.  The association of certain blue & red with political parties or ideologies is fairly consistent in the English-speaking world except for the curious pattern of use in the United States.

Flags of the US Republican Party (Elephants) & US Democrat Party (Donkeys).

In the US, although the idea of blue states (Democrats) and red states (Republicans) is now entrenched as part of the political lexicon, it's been that way only for two decades odd.  Red and blue had long been used to illustrate the US electoral map but there was never any consistency in how they were allotted to the parties and in some elections, different television networks might use them differently or even use different colors entirely, one of the considerations being what worked best on the then novel medium of color television.  The other influence was possibly political culture, there being in the US little tradition of a mainstream, radical party of the left so the red-blue contrast as it was understood elsewhere in the English-speaking world didn't register in the same way.  It was in the 2000 presidential election that the television networks agreed to standardize the red and blue designations for Republicans and Democrats, the incentive simply one of convenience in the reporting of the drawn-out Electoral College numbers that year.  As the red and blue imagery flowed across screens for weeks before the numbers were settled, the color associations became set in stone.

The idea of the US as a divided society of red states (emblematically the fly-overs) and blue states (with populations on the corrupting coastlines) is graphically illustrated when the states are colored according to the winner-takes-all system electoral college system but if the red-blue map is instead constructed county by county, a more nuanced spectrum emerges as one that is in shades of purple (purple a mix of red & blue as teal is of green & blue).  The US is a country of divisions and many of the cleavages are cross-cutting but the state by state maps do exaggerate the extent of the political polarization.

Turquoise

Turquoise (pronounced tur-koiz or tur-kwoiz)

(1) A fine-grained secondary opaque mineral, a basic hydrous copper aluminum phosphate often containing a small amount of iron, sky-blue to greenish-blue in color (also as the rare form turquois).  It occurs, usually in reniform (kidney-shaped) masses with surfaces shaped like bunches of grapes, especially in aluminum-rich igneous rocks such as trachyte.  In its polished blue form (it occurs also in a yellowish-green hue) it is prized as a gem.  Formula: CuAl₆(PO₄)₄(OH)₈·4H₂O.

(2) A color in the blue spectrum, described usually as bluish green or greenish blue and known also (for commercial purposes) as turquoise blue.

(3) A gemstone (categorized as a semi-precious) made of the mineral, the hues tending to blue traditionally more valuable than the greens.

(4) One of the birthstones for the month of December and associated with the zodiac signs Sagittarius and Capricorn.

1300s or 1600s:  The origin is contested.  Some etymologists trace it from the seventeenth century when it was picked up from the Middle French turquoise, from the Old French (pierre) turquoise (Turkish (stone)), the construct being turc (Turk) +‎ -oise (the feminine of -ois and the suffix used to form adjectives related to a particular country, region or city, their associated inhabitant names, and the local language or dialect), simply because the mineral ( mined near Nishapur in the Khorasan region of Persia) first reached Europe in the hands of the Turkish traders (from the modern-day Republic of Türkiye) of the Ottoman Empire (thus essentially the same manner in which the bird known as the Turkey gained its name) .  Others claim it dated from the fourteenth century as an adaptation of the Middle English turkeis & turtogis (Turkish) which in the 1560s was replaced by the French turqueise.  Those supporting the later etymology claim the gemstone was first brought to Europe from Turkestan or another Turkic territory.  Pliny the Elder (24-79) called the mineral callais (from the Ancient Greek κάλαϊς) and to the Aztecs it was chalchihuitl.  It was cognate with the Spanish turquesa, the Medieval Latin (lapis) turchesius, the Middle Dutch turcoys, the German türkis and the Swedish turkos.  Adjectival use began in the 1570s and it came to be used a colour name in the 1850s.  The use of the spelling turkies is archaic and turquois is rare.  Turquoise is a noun & adjective ane turquoisish, turquoisey, turquoisy¸ turquoised & turquoiselike are adjectives; the noun plural is turquoises.

Turquoise is often used in jewelry although some pieces sold as “turquoise” can be artificial and actually only turquoise-colored (with the dual meaning of the word it’s essential to read the small print).  Turquoise used in jewelry is often cut in the form of a cabochon (an oval shape polished but not faceted) and these, in a variety of sizes, are popular for pendants, broaches and earrings.  Turquoise was mentioned in the writing of the Venetian merchant Marco Polo (circa 1254–1324) who saw examples while in China and in the US, turquoise jewelry is especially associated with Native American artisans, particularly from tribes of the south-west including the Navajo & Hopi.

As a descriptor of color, turquoise is commonly used but it’s inexact, even by the standards of commercial color charts and what some call turquoise others might describe as teal or cyan and the mineral itself exists in quite a range.  The various shades of blue anyway exist in quite a spectrum including: Alice blue, aqua, aquamarine, azure, baby blue, beryl, bice, bice blue, blue green, blue violet, blueberry, cadet blue, Cambridge blue, cerulean, cobalt blue, Copenhagen blue, cornflower, cornflower blue, cyan, dark blue, Dodger blue, duck-egg blue, eggshell blue, electric-blue, gentian blue, ice blue, lapis lazuli, light blue, lovat, mazarine, midnight blue, navy, Nile blue, Oxford blue, peacock blue, petrol blue, powder blue, Prussian blue, robin's-egg blue, royal blue, sapphire, saxe blue, slate blue, sky blue, teal, turquoise, ultramarine, Wedgwood blue & zaffre.

The vivid color range of turquoise must have attracted the eyes of humans as soon as they discovered the stone; it is one of the gems with the longest history of decorative use and while it’s not certain how ancient is the tradition, the archaeological record has revealed the upper classes of ancient Egypt wore turquoise jewelry more than 4000 years ago and it’s clear Chinese artisans were carving objects from the stone by at least 1000 BC.  The national gem of Tibet, it has long been valued as a stone which will bring the wearer wealth, health and protection from evil.  It assumed also some military significance because certain tribes of the Apache in what is now the south-western United States believed turquoise attached to a bow or firearm increased a hunter’s (or warrior’s) accuracy of fire.  More pragmatically, the stone also was used as a medium of exchange for among many Native American tribes although being relatively plentiful, as a form of currency its utility was limited and it was valued more for its attractiveness.

Being relatively soft turquoise can be easy to carve but that very attribute can also induce fragility so the selection of a stone for this purpose is best allocated to an expert.  Like most materials, it's a patchwork of strengths and weaknesses: With a Mohs hardness typically between 5-6 it's softer than quartz (rated at 7) but harder than most organic materials like bone or ivory.  That means most standard lapidary tools can be used for carving but does render it susceptible to scratching.  Additionally, many turquoise deposits are porous and often contain inclusions or matrix (ie the host rock) which makes it prone to chipping, crumbling, or breaking along weak spots if too much pressure is applied.

1962 Ferrari 250 GT SWB (short wheelbase) California Spider.

In March 2023, at the annual auctions on Amelia Island, Florida (the old four-day Amelia Island Concours d’Elegance) a 1962 Ferrari 250 GT SWB California Spider sold for US$18,045,000, passing under Gooding & Co’s hammer.  The SWB Spiders have for years be prized but this one attracted a premium because of aspects which attested to its particular rarity, being one of only 37 (some say 47) of the 106 made with the (soon to be unlawful) Perspex-covered headlights and the only one the factory finished in azzurro metallizzato, an eye catching turquoise.  In the way the Italian language manages like no other, azzurro metallizzato sounds much better the the literal translation “metallic sky blue”.  The car was prepared especially for the 1962 New York International Auto Show and remarkably, after being damaged in an accident in 1971, was sold the following year for US$2400 (around US$18,000 adjusted for inflation), so in fifty-odd years it has appreciated around a thousand-fold.  There was of course a repair and restoration bill to be paid in 1972 and the many costs of ownership since but however it’s analyzed, the thing has proved a good investment (although there will be accountants anxious to prove the same US$2400 invested in the right stock index or whatever would have been more lucrative still).  While in the public imagination Ferraris are most associated with red (and the classic rosso corsa (racing red) is just one of many reds the factory has offered), shades of blue have always been popular and over the years there have been dozens.

Ms Justine Haupt (b 1987), an astronomy instrumentation engineer at New York’s Brookhaven National Laboratory took a step backwards (or perhaps sideways, some might suggest) and built a rotary-dial cell phone from scratch because of her aversion to what she describes as “smartphone culture and texting”, something to which many will relate.  In what proved a three year project, Ms Haupt used a rotary-dial mechanism from a Trimline telephone (introduced in 1965 and produced by Western Electric, the manufacturing unit of the Bell System), mounted on a case 4 x 3 x 1 inches (100 x 75 x 25 mm) in size with a noticeably protuberant aerial; it used an AT&T prepaid sim card and had a battery-life of some 24-30 hours.  Conforming to the designer’s choices of functionality, it includes two speed-dial buttons, an e-paper display and permits neither texting nor internet access.  

Designer colors: Available in black, white, turquoise, beige and the wonderful Atomic Hotline Red.

“Atomic Hotline Red” is an allusion to the Moscow-Washington DC “hotline” installed in the aftermath of the Cuban Missile Crisis (October 1962). In truth, despite frequently appearing in popular culture, there never was a “red phone” and the US connection terminated not on the POTUS’s desk in the Oval Office but in the Pentagon (now HQ of the Department of War) in Arlington County, Virginia.  The first implementation in 1963 used a version of Telex while it was an analogue facsimile service (ie fax machines) between 1986-2008.  Since 2008 the data has travelled over a secure digital link, decrypted into text at each end.

Although she intended the device as a one-off for her own use, Ms Haupt was surprised at the interest generated and in 2022 began selling a kit (US$170) with which others could build their own, all parts included except the rotary-dial mechanism which would need to be sourced from junk shops and such.  Unfortunately, Ms Haupt encountered many difficulties (bringing to market a device which connects to public telephony networks involves processes of greater complexity than selling mittens and such) but the project remains afoot.

1250–1300: From the Middle English skyrte & skirte (lower part of a woman’s dress) from the Old Norse skyrta (shirt; a kind of kirtle) from the Proto-Germanic skurtijǭ (skirt).  The sense development from "shirt" to "skirt" is thought most likely related to the long shirts of peasant garb (the Low German cognate Schört, in some dialects translates as "woman's gown").  The meaning "border, edge" (in outskirts, etc) was first recorded in the late fifteenth century and the metonymic use for "women collectively" emerged as early as the 1550s although there’s no evidence the slang sense of "young woman" existed prior to 1906 with “skirt-chaser” (a womaniser) first attested 1942.  The mini-skirt dates from 1965, reputedly the invention of French designer André Courrèges (1923-2016).

Annotated schematic of Ford Y-block V8 (left) and a 430 cubic inch (7.0 litre) MEL V8 during the restoration of a 1958 Lincoln Premiere Coupe in Autumn Rose & White (right).  The MEL V8 was also in the "Y-block" shape but is never referred to as such because the identifier MEL (Mercury-Edsel-Lincoln) is used.  Thus the 239-256-272-292 & 312 Ford V8 and 279-302-317-332-341 & 368 Lincoln V8 families are the Y-blocks while the MEL (383-410-430 & 462) MEL V8 is a Y-block type design.

The Ford & Lincoln “Y-block” V8 engines gained their nickname from the deep skirting of the block which extended below the crankshaft line, making for an unusually robust bottom end, something which would prove of some significance long after the unit had in the US been supplanted by more modern designs.  In many ways the Y-blocks were a curious cul-de-sac in the evolutionary path of the US V8 engine, having an unusual port design which rendered development by conventional means impossible (hence the brief resort to supercharging) and the dimensions limited the potential for increased displacement.  It was noted also for the unique arrangement of the solid valve lifters which had to be installed from below and a firing order which produced a distinctive and pleasing burble from the exhaust.  Compared with Ford’s earlier and later V8s, both the Y-Blocks were short-lived, the Lincoln (some of which were actually used in Ford trucks) used between 1952-1963 while the Ford lasted from 1954 until 1964, their replacements both adopting a more conventional design approach.  However, the Ford lived on in Romania until 1975 where it was produced under licence as a truck engine (the durability of the tough, deep-skirted block an asset in a market where conditions were tough and the quality of oil and fuel sometimes suspect) and in Argentina until 1988, the South Americans improving things greatly with their re-designed heads which used conventional porting.

The Pencil Skirt

A pencil skirt is a slim-fitting garment with a severe, narrow cut.  The classic design was approximately knee-length but modern, more flexible fabrics have made possible calf-length styles.  It borrows its name from the writing instrument because, tailored for a close fit, it is pencil-like: long and slender.  Flexible in use, it’s the quintessential mix-and-match item, able to be worn either as a separate piece or as part of an ensemble.  A vent is usually placed in the back (or increasingly at the sides, especially in longer styles) because the slim shape would otherwise impede movement although a more modest kick pleat can instead be used.  Modern stretchy fabrics have made practical functional pencil skirts without either vents or pleats but they seem still popular for aesthetic reasons.  Historically, the industry paired pencil skirts with stilettos or court shoes but they’re now worn in just about any combination, boots proving increasingly popular.  French designer Christian Dior (1905–1957) included a classic pencil skirt in his 1954 Autumn-Winter collection although the style had long been worn.  Economical in the use of fabric compared with more voluminous cuts, its popularity had been boosted by war-time rationing and post-war austerity.

The pencil skirt’s precursor was the hobble skirt, an Edwardian-era fad inspired by the Ballets Russes, a Paris-based ballet company which, between 1908-1929, performed in the Americas and Europe (though paradoxically never in Russia because of the political convulsions).  Highly influential, Ballets Russes brought modernism to ballet with works commissioned from Stravinsky, Debussy, Prokofiev, Satie and Ravel, and their artistic collaborators included Kandinsky, Benois, Picasso and Matisse.  Coco Chanel (1883–1971) was one of their costume designers but it’s not known if she penned the hobble skirt.
