porcelain: [16] The bizarre history of the word porcelain leads us back to a pig’s vagina. It was originally applied to fine china in Italian, as porcellana. This meant literally ‘cowrie shell’, and was used for the china in allusion to its shelllike sheen. Porcellana was a derivative of porcella ‘little sow’, a diminutive form of porca ‘sow’ (to which English pork is related), and was applied to cowrie shells because they supposedly resembled the external genitalia of female pigs. English acquired the word via French porcelaine. => pork[porcelain etymology, porcelain origin, 英语词源]
