'''Collodion''' is a flammable, syrupy solution of [[nitrocellulose]] in [[Diethyl ether|ether]] and [[Alcohol (chemistry)|alcohol]]. There are two basic types: flexible and non-flexible. The flexible type is often used as a surgical dressing or to hold dressings in place. When painted on the skin, collodion dries to form a flexible nitrocellulose film. While it is initially colorless, it discolors over time. Non-flexible collodion is often used in theatrical make-up. Collodion was also the basis of most [[Collodion process|wet-plate photography]] until it was superseded by modern gelatin emulsions.
