Selluloidien

Selluloidien is a term that refers to the cellulose nitrate film base used in early motion picture film stock. It was developed by the French chemist Paul L. T. Héroult in 1885 and became the standard film base for motion pictures from the late 19th century until the mid-20th century. Selluloidien is composed of cellulose nitrate, which is highly flammable and sensitive to heat, light, and moisture. This sensitivity made it a significant safety hazard in film production and storage.

The use of selluloidien in motion pictures began to decline in the 1950s due to its flammability and the introduction of safer film bases such as cellulose acetate and polyester. The last major motion picture to be shot on selluloidien was "The Ten Commandments" in 1956. Despite its eventual replacement, selluloidien remains an important historical artifact, providing valuable insights into the early days of cinema and the evolution of film technology.
