Answer:
A. Artists made porcelain from a mixture of pure white clay and feldspar.
Step-by-step explanation:
Porcelain is a ceramic made from a white mass composed mainly of kaolin (a type of strong white clay), combined with ordinary clay and the minerals called quartz and feldspar. It is coated with a clear enamel layer and baked in the oven at 1,450 ° C, making it glazed. Porcelain stands out for being waterproof and semi-transparent.
