== Description ==

A decorative paper that has an iridescent surface. Patents were issued in 1855, 1864 and 1866 for the preparation of iridescent paper by floating glazed paper in a bath of silver or lead salts, then exposing the dried paper to hydrogen sulfide gas. An alternative procedure was to soak the paper in a solution of gum, iron sulfate, sulfate of indigo and nutgalls then exposed the dried paper to ammonia fumes. Today, iridescent paper is produced by special printing techniques and dyes.
