Abstract
An article e.g. a sound record or a glass ornament, on a rotating disc 4 is silvered by spraying various solutions through adjustable <PICT:1058021/C6-C7/1> nozzles 20, and the solutions are drained through a two-way cock either to a drain or to a receptacle 9. The process comprises rinsing with water, degreasing, rinsing, sensitizing, rinsing, simultaneously spraying through two nozzles the silvering solution and a reducing agent, and finally rinsing. The sensitizing solution is stannous chloride and HCl. The silvering solution is 12.5 g./1. of silver nitrate titrated with ammonia. The reducing agent is 22.5 g./1. of glucose and 2 mls. of 37% formaldehyde. Soda lye may also be mixed with the silvering solution during spraying. The operation of the apparatus may be controlled electrically. The liquids are fed from pressurized reservoirs 3.
