The modern electroplater; a complete book considering fully the elementary principles of electro deposition of metals, their practical application and industrial use . x. Fig. 102.—Cotton Potash Brush (Crown Rheostat & Supply Co.) therefore, a precautionary measure to remove all pos-sible existing oxide. No time should thus be lost inplacing the work in the electrolytic solution after ithas passed through the la t rinsing Fig. 103.—Goblet Shaped Brush(General Platers Supply Co.) The same general operations may be followed forcleaning brass and copper objects with the exceptionof the final acid dip. To remove the oxide accumula-tion, a potassium cyanide dip is substituted for the Stripping 157 muriatic acid. After rinsing in cold water, the workis immediately placed in the plating tank. It mightbe worth mentioning that finely polished brass andcopper articles rarely require scouring, but this is,of course, a question to be decided by the plater. Avariety of scouring and cleaning brushes, for differentclasses of work, are shown in Figs. 102, 103 and 104. STRIPPING It is not unusual in the production of commercialwork to discover, after plating is completed, thatsome mechanical operation has been omitted or that,through accident, perhaps, the original finish is dam-
