 made by treating cellulose nitrate with camphor and alcohol. Celluloid was the first important synthetic plastic and was widely used as a substitute for more expensive substances, such as ivory, amber, horn, and tortoiseshell.

It has been used for combs, brush handles, billiard balls, knife handles, buttons, and other useful objects.

Celluloid

 

a plastic based on cellulose nitrate (pyroxylin). It also contains a plasticizer (dibutyl phthalate, castor oil, petrolatum, or synthetic camphor) and a dye. Celluloid is processed by hot stamping, pressing, and mechanical working. It is used in the manufacture of various products, including plane-table boards, rulers, certain haberdashery goods, and toys.
