Origins
The word 'porcelain' contains one of the most improbable etymological journeys in any language β a cβββββββββββββββββββββββββββββββββββββββββββββββββββββββββββββββhain of associations that leads from a Chinese imperial kiln to a cowrie shell on an Italian beach to the reproductive anatomy of a pig.
The story begins with Latin 'porcus' (pig), which derives from Proto-Indo-European *porαΈ±-os (young pig) β a root also found in Old English 'fearh' (young pig, farrow) and Irish 'orc' (pig). Italian inherited 'porcus' as 'porco' (pig), and the feminine diminutive 'porcella' (little sow) was formed from it. So far, nothing remarkable.
The first unexpected turn occurs in Italian natural history. The cowrie shell β a small, smooth, glossy sea shell with an elongated slit-like opening β was called 'porcellana' in Italian, because its opening was thought to resemble the vulva of a sow ('porcella'). This comparison was crude but widely understood, and 'porcellana' became the standard Italian name for the cowrie shell. The comparison between shells and animal anatomy was not unique to Italian β in several languages, cowrie shells have been named after female anatomy.
Development
The second unexpected turn occurs when European traders first encountered Chinese porcelain ware. Italian merchants, particularly Venetians trading along the Silk Road, saw the smooth, white, translucent surface of Chinese ceramic and recognized a resemblance to the cowrie shell they already called 'porcellana.' The cowrie shell and the Chinese ceramic shared the same qualities: a luminous whiteness, a smooth glaze-like surface, and an almost translucent quality when held up to light. The name transferred from shell to ceramic, and 'porcellana' became the Italian word for Chinese pottery.
French borrowed the word as 'porcelaine,' and English took it from French as 'porcelain' in the 1530s, during the period when Chinese ceramic ware was beginning to reach Europe in significant quantities through Portuguese trade routes. The material was enormously admired and fantastically expensive β a single piece of Chinese porcelain could be worth more than a house in sixteenth-century Europe.
The Chinese had been producing porcelain for over a thousand years before Europeans encountered it. True porcelain β fired at temperatures above 1300 degrees Celsius from a mixture of kaolin (china clay) and petuntse (a feldspathic rock) β was developed during the Tang Dynasty (618-907 CE) and perfected during the Song Dynasty (960-1279 CE). The blue-and-white porcelain of the Yuan and Ming Dynasties (13th-17th centuries) became the most coveted luxury commodity in global trade.
Later History
European potters spent centuries trying to replicate Chinese porcelain and failing. The secret β the specific combination of materials and the extreme firing temperatures required β eluded them until 1708, when Johann Friedrich BΓΆttger and Ehrenfried Walther von Tschirnhaus succeeded in producing true hard-paste porcelain at Meissen in Saxony. The Meissen porcelain factory, established in 1710, became the first European producer of porcelain, and its products were guarded as state secrets β workers were effectively imprisoned to prevent the technology from spreading.
The PIE root *porαΈ±-os produced a constellation of pig-related words in English. 'Pork' (pig meat, via Old French 'porc'), 'porcupine' (literally 'spiny pig,' from Old French 'porc espin'), 'porcine' (pig-like), and 'porpoise' (literally 'pig-fish,' from Old French 'porpois,' from Latin 'porcus piscis') are all relatives. The idea that 'porcelain' belongs in this family β that the word for the most refined ceramic material in the world is etymologically a pig word β is one of the great comedies of historical linguistics.
In modern English, 'porcelain' denotes both the material and objects made from it. It carries connotations of refinement, fragility, and beauty β 'porcelain skin' is a compliment describing a flawless, luminously pale complexion. The word has traveled so far from its porcine origins that no native English speaker, hearing 'porcelain,' thinks of pigs, shells, or anatomy. The chain of associations that created the word has been completely effaced by centuries of use, leaving behind only the image of white ceramic perfection.
