What Is A Ceramic Mold

What is ceramic Mould?

The ceramic molding process is a production method which guarantees the precision required, and also gives a good surface finish, using a high temperature method to better structure and shape parts. The patterns that ceramic mold uses are plaster, plastic, wood, metal, rubber, etc.

How do ceramic molds work?

Very simply, the casting process creates a clay shape from a mold. Slip (liquid clay) is poured into the plaster mold. When the casting’s thickness is between ⅛ and an inch thick (total time in mold – 15-18 minutes), you can separate the two halves of the mold to remove the greenware (unfired clay shape).
