Scope note
Photographic prints made on a gelatin-silver chloride photographic paper introduced commercially in 1867 by the Munich-born chemist Johann Baptist Obernetter. This was considered the first industrial ready-to-use photographic paper print process. Aristotypes are composed of a paper layer, a layer of baryum sulphate in gelatin, and a layer of emulsion containing silver chloride suspended in a binder. The baryta layer made purer whites possible. As this was was a printing-out-paper, aristotypes are exclusively contact prints.
