Ceramical is a form of hydrocal gypsum cement. Its consistency is 40,
(40 parts of water to 100 parts of ceramical, by weight)
it is primarily used for making RAM press molds, though this would not
preclude it from being used for other types of molds
it has good strength, but also purges well during the making of RAM
press molds.
a great website for info on different types and properties of plaster,
gypsum cements, etc is
