Abstract

254,330. Glasfabrik Akt.-Ges., and Stein, G. June 25, 1925, [Convention date]. Drawings to Specification. Materials for moulds. - A mould or tool for working glass, particularly a cast iron mould in which a pattern has been cut, is hardened by coating its working-surface with a layer of chromium. The mould may be coated with the chromium by electrolyte deposition from a solution of chromium chromate and chromic acid. in water.
