What's the difference between porcelain and translucent?
Porcelain
Definition:
(n.) Purslain.
(n.) 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.

Translucent
Definition:
(a.) Transmitting rays of light without permitting objects to be distinctly seen; partially transparent.
(a.) Transparent; clear.
Example Sentences:
