Type of porcelain food container (8)
I believe the answer is:
eggshell
'type of porcelain' is the definition.
(I've seen this before)
'food container' is the wordplay.
'food' becomes 'egg' (egg is a kind of food).
'container' becomes 'shell'.
'egg'+'shell'='EGGSHELL'
(Other definitions for eggshell that I've seen before include "Delicate sort of china" , "Holder of the white and yellow" , "that soldiers have to get through" , "formed in layers" , "Thin, translucent china" .)
