The Basics

A mold is a hollow plaster form in which articles

are reproduced through the use of liquid clay. The

plaster walls of the mold absorb water from the clay

slip, producing the clay shell, or casting.

A mold can be open-faced (one-piece) or made in

sections (multiple-piece) held together with thick

rubber bands or straps.

A ceramics mold is plain on the outside. The inside of

the mold determines the shape of the casting. It can

be compared to a mirror or reverse image, because

the raised areas of the casting are hollow in the

mold, just as the incised areas are raised.

Every mold has one or more openings, called pour

holes, for the slip that will be poured into the molds.

The process of pouring slip into a mold is called

casting.
