Lacquering is the coating of any metal with a hard, skinlike transparent film, either colorless or colored as desired, the purpose being to improve the appearance of the finished article and to protect it from the tarnishing and corroding influences of the atmosphere. It is also of value in protecting the plate from being worn off as readily as it would be if not lacquered. The lacquered articles may be wiped off with a soft, damp cloth, or dusted; they may even be washed with lukewarm water and soap, if necessary. Lacquer improves the appearance and increases the durability of all brass, bronze and copper goods, also sterling silver and silver and gold-plated goods. The susceptibility of most metallic surfaces to atmospheric influences is so great that it is indispensable to lacquer them to protect them. Even packing in damp paper or contact with the hand may produce sufficient oxidation to entirely spoil the appearance which the metal is intended to produce. The protecting layer must be such that it must cover without concealing the metal or affecting its luster, and must, of course, have no tendency to oxidize it or injure its brilliancy in any way. Ordinary spirit lacquers are quite unsuitable, as they change the appearance of the surface entirely. The lacquers which answer the purpose fully--i. e., remain invisible while affording full protection--are the celluloid lacquers. They are also so elastic that they never peel or crack off. They may be easily made by the plater in an emergency, but should always be bought where possible, as the purchased article will be found to be both cheaper and better. If the plater desires to make such a lacquer, he may do so by dissolving transparent...
