Chromic Acid is an oxidizing agent and is an excellent cleaning mixture for cleaning glass and is also used in the instrument repair industry, due to its ability to brighten raw brass. It is used as an intermediate agent in plating, in the production of ceramic glazes, etching of plastic parts prior to metalizing and in manufacturing colored glass.
