Celluloid is a material invented around 1863,<ref>the invention is attributed to John Wesley Hyatt, but there are several predecessors (its origins date back to the work of Alexander Parker in England); also the exact date of its origin is uncertain, as usual you can see details in the Wikipedia [http://en.wikipedia.org/wiki/Celluloid page] on celluloid.</ref> produced from the processing of nitrocellulose and pigments in a solution of camphor and ethyl alcohol. The material when heated (about 60°) becomes malleable and may be bent and also moled; for this is considered as the first thermoplastic resin produced.

Celluloid is an elastic material and it is shatterproof, shock resistant and waterproof. Its origin stems from the search for a replacement for billiard balls production, but was soon used for many other applications, such as combs, knife handles, and especially as support for photographic film. Today, apart from some fountain pens, is used for ping pong balls and guitar picks.
