Pictured: porcelain - from Middle French porcelaine and directly from Italian porcellana “porcelain” (13c.), literally “cowrie shell,” the chinaware so called from resemblance of its lustrous transparency to the shiny surface of the shells. The shell’s name in Italian is from porcella “young sow,” fem. of Latin porcellus “young pig,” diminutive of porculus “piglet,” diminutive of porcus “pig.”
