silvering
process of making mirrors by coating glass with silver, discovered by the German chemist Justus von Liebig in 1835. In the process silver-ammonia compounds are reduced chemically to metallic silver, which is deposited on a suitably shaped glass surface. Modern processes may utilize silver solutions and reducer solutions-consisting of invert sugar, Rochelle salt, or formaldehyde-that meet in a spray above clean glass traveling on a conveyor; as the spray falls on the glass surface, metallic silver is deposited.
