Porcelain (277) , noun

[French porcelaine, Italian porcellana, orig., the porcelain shell, or Venus shell (Cypraa porcellana), from a dim. from Latin porcus pig, probably from the resemblance of the shell in shape to a pig's back. Porcelain was called after this shell, either on account of its smoothness and whiteness, or because it was believed to be made from it. See Pork.]

A fine translucent or semitransculent kind of earthenware, made first in China and Japan, but now also in Europe and America; -- called also China, or China ware.
Porcelain, by being pure, is apt to break. — Dryden
