A hard striped wood obtained from ''Guibourtia tessmannii'' and ''Guibourtia demeusei'' trees found in western Africa. Bubinga, or African rosewood, has either a light red, brown or violet background with evenly spaced pink or purple stripes. It has a medium texture and polishes to a high gloss. Bubinga is a decorative wood that is used for furniture, cabinets, veneer, pianos, and decorative items (handles, brushes, boxes, etc.).

Description

[Schenz Theatrical Supply] A textile impregnated with Cellulose nitrate. Celastic becomes moldable when activated with heat and tacky when activated with solvent (Acetone or 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.
