Calcine in a crucible and keep 80 GOLDPLATING at a glowing heat over a gas burner until all the litharge hasbeen decomposed, leaving a button of lead and gold withthe silver, copper and other metals of the alloy. This maybe sent to the assayer, who will allow for the precious. Fig. 54. Lathe Buff for Goldplating metals it contains. Unless the plater is an expert chemist,however, he had better not undertake the delicate processof reduction. The tools and articles used in goldplating should be keptfor that purpose only, and not mixed up with others. Thebrushing and cleaning may be done entirely by hand, but ifmuch work of this character is done a small lathe will befound useful. A small scratchbrush of fine brass wire,
