Standard Clay Company Hydrocal

Description

For strong cast, hydrocal works as easily as plaster. Use it where strength counts: for patterns, figurines, commercial casts and sculpture. 30% to 40% harder than casting plaster and a medium porous gypsum, works much like casting plaster in mixing, pouring and setting.It cannot be used to make outer or mother molds and is recommended for casting only. It is not recommended for outdoor use.
