[0002] Ceramics are various products made primarily from clay and various natural minerals through crushing, mixing, molding, and firing. The production of ceramic blanks generally involves placing clay blocks containing a certain amount of moisture into a plaster mold, then placing the plaster mold on a molding machine to form the blank. After the blank is formed, the plaster mold and the blank are removed from the molding machine and transferred to a place for drying and dehydration.
