ABSTRACT:
A molding kit to facilitate the synthetic cloning of body parts, such as fingers, the kit including a supply of alginate powder and a mold form having a bottom opening that is sealed when the form is seated on a base. A charge of powder is mixed with water to form a quick-setting, flowable molding compound. This is poured into the mold form, after which the body member is inserted and held therein until the compound sets to form an elastic gel. The gel is then pushed out of the mold form through the bottom opening, and the body part withdrawn to expose the impression cavity. The gel is returned to the mold form which is again seated and a flowable casting compound of the same composition as the molding compound is poured into the cavity and permitted the set to create a flesh-like clone of the body part. This clone is readily removable from the cavity without marring the impression therein.
