"DRY" GALVANISING MADE EASY.

The process of galvanising iron to protect it from moisture is of special importance in countries where the atmosphere Ts humid. Complicated plant is generally required for the process, which consists of covering the iron with a layer of zinc. Recently, however, a British firm has introduced a simple apparatus which can readily be installed in any workshop. It consists of two parts, in the first of which the articles to be treated are placed in a bath of zinc dust and heated—the heating being done by electricity, gas, or oil. The zinc dust \aporises and forms a close covering flcihering to the iron or steel. The second part consists of a rotating drum, in which the covered articles are revolved to shake off the excess dust. So simple is that plant that it can be operated by unskilled labour; and the results are better than by the old-fashioned process of galvanising in a bath. Screws, bolts, motorcar parts, articles of art metal, and so on can be readily treated.
