What is celluloid?

celluloid is a material made by nitrocellulose sculpture with the help of coffee. This substance was first invented in the 18th century as a replacement for ivory and bones, and its use later spread significantly, perhaps especially into the world of film. In the 1950s, however, the disadvantages of celluloid led to a general decrease in the material market and today can be difficult to find. When plasticizing with coffee, the resulting material is very easy to form, shape and handle. However, it has a very distinct disadvantage: it is highly flammable. The celluloid is so flammable that it will continue to burn, even if it is soaked in water, which makes it a serious danger of fire, as one can imagine. It is also not too light stable, it quickly decomposes when it is exposed to light. For example, in corset -technical, it could help maintain a form without rust, as was the case with metal stays and the flexibility of celluloid also allowed some freedom of movement by the wearer. Celluloid was even briefly used to make very durable clothing, although several nEspecially stopped this practice.

This substance was sold for the first time as a parzin and later as xylonite. The term "celluloid" was originally a trademark, which was discarded in 1869, but thanks to the dilution of the trademark, it became more generally to refer to plasticized nitrocellulose than on the specific brand of this product. Originally, celluloid was used to produce things such as corset stays, pool balls and a number of other objects that were made of bone; When his potential was realized as a photographic film, celluloid production took off significantly.

until the age of 40. At that time it turned out to be quite dangerous, because the fires for the design room began easily and it was hard to release them. In retrospect, the use of celluloid was also widespread as a great shame, because the film with time of yellow and cracks and as a result wasMany great movies lost to history. Today, acetate and polyester are used to shoot a film, but celluloid still has an iconic place in the film world due to its role in early film production.
