Choose traditional pristine white casting plaster; pure white, smooth, slow-setting plaster for casts molds and direct modeling or try Hydrocal. Hydrocal works as easily as plaster. It is 30% - 40% harder than casting plaster and works much like casting plaster in mixing, pouring, and setting. It cannot be used to make an outer mold and is recommended for casting only. Ideal for: patterns, figurines, commercial casts and sculpture.


Life casting or body casting is the art of taking molds directly from the human body. It is an ancient art form dating back to the time of the Egyptians. ArtMolds specializes in mold making and casting materials that are environmentally safe. Whether you’re looking to reproduce a sculpted figure, antique picture frame, architectural molding, fossils or fabric texture, all start with a liquid rubber or silicone mold. Molds can made from original models made of clay, wax, plaster, sand, concrete, stone or metal. With a mold, you can reproduce an original once or one thousand times!
