· 4. Make your plaster for the mold by mixing water and plaster of paris (gypsum) powder at a 3:4 weight ratio (i.e., 30 grams of water to 40 grams of plaster of paris). This weight ratio of water to powder is very important, so be sure to weigh carefully. It is also important that the two are well mixed.

Hardening and Toughening Plaster of Paris
I. Plaster of Paris at times sets too rapidly; therefore the following recipe for toughening and delaying drying will be useful. To calcined plaster of Paris add 4 per cent of its weight of powdered marshmallow root, which will keep it from setting for about an hour, and augment its hardness when set, or double the quantity of marshmallow root powder, and the plaster will become very firm, and ...

Understanding the Deflocculation Process in Slip Casting
The plaster absorbs water from the slurry building up a layer against the mold surface. When this layer has reached the desired thickness the slurry is poured back out of the mold. The mold then sits for a few minutes (or hours if it is large) and the clay article slowly stiffens, shrinks and pulls away from the plaster.
