Description
An abrasive powder composed of fine, ultrapure, Red iron oxide. Jewelers' rouge is synthetically prepared by heating ferrous sulfate. Also called colcothar, it is used as an abrasive for the final polish on glass and soft metals, such as Gold and Silver. It is applied either dry or as a thick aqueous paste. The round edge ferric oxide particles burnish the metal rather than cut channels as does the harder Alumina abrasives.
