Collodion
Collodion
Collodion (pronunciation: kəˈlōdēən) is a flammable, syrupy solution of Pyroxylin (nitrocellulose) in ether and alcohol. There are two major types: flexible and non-flexible. The flexible type is often used in theatrical make-up and as a medical dressing. The non-flexible type is used in theatrical make-up and photography.
Etymology
The term "collodion" comes from the Greek words "kolla," meaning glue, and "eidos," meaning like. It was first formulated in 1846 by the French chemist Louis Ménard, who was looking for a way to make a clear, flexible film.
Uses
Collodion is used in a variety of applications, including as a surgical adhesive, in the production of photographic plates, and in special effects makeup. It is also used in the treatment of wounds and skin conditions, such as corns and calluses.
