Celastic

Description

A textile impregnated with nitrate cellulose nitrate. Celastic becomes moldable when activated with heat and tacky when activated with solvent (acetone or ethyl ketone MEK). When dry and cool, it forms a stiff, lightweight shell. It was used by model makers, taxidermists, and orthopedists for lightweight support. Celastic has been used for reinforcing joins on fragmentary archaeological vessels. In recent years, Celastic has been replaced in favor of less toxic materials including Varaform, Wonderflex, and Fosshape.
