Editing Collodion (section)

==Other uses==
* Non-flexible collodion is used in theatrical [[makeup]] for various effects. When applied to the skin, it shrinks as the solvent (usually ether or alcohol) evaporates, causing wrinkles and is used to simulate old age, or scars.
* Collodion is used in the cleaning of [[optical|optics]] such as [[telescope]] mirrors. The collodion is applied to the surface of the optic, usually in two or more layers. Sometimes a piece of thin cloth is applied between the layers, to hold the collodion together for easy removal. After the collodion dries and forms a solid sheet covering the optic, it is carefully peeled away, taking contamination with it.
* Collodion is a pure type of pyroxylin used to embed specimens which will be examined under a [[microscope]].
* While in Paris, [[René Dagron]] became familiar with the collodion wet plate and collodion-albumen [[dry plate]] processes which he would later adapt to his [[microfilm]] and [[Stanhope (optical bijou)|Stanhope]] production techniques.
* Collodion was used by [[Alfred Nobel]] in his development of [[blasting gelatin]], a more powerful, flexible, and water resistant variation of his already-successful [[dynamite]].
* Some types of [[nail polish]] also contain collodion.<ref>Cosmetic Ingredient Review (2013), [http://www.cir-safety.org/sites/default/files/nitroc062013FR.pdf "Safety Assessment of Nitrocellulose and Collodion as Used in Cosmetics"]</ref>
