From GR Pottery Forms wood drape molds are ideal for making dinnerware and serving platters. They are cut and beveled fiberboard which make them durable and economical. Easy to use over and over again giving you a tool to create your personalized shallow objects. No release agent or sealing necessary. The timing of making them and removing the pieces from the slab is very similar to plaster. They are made of wood fiberboard. They will not last as long if they are left in a wet condition for over a 24 hour period.
