Website design By BotEap.comceramic plaster
Website design By BotEap.comThis is a high quality white plaster with the ability to absorb large amounts of moisture. This makes it ideal for use as a ceramic mold by absorbing water from the ceramic slip used in casting. This leaves a semi-dry reproduction of the shape thick enough to allow it to be demoulded for subsequent kiln firing, after the excess slip has been poured from the mould.
