The proce or art of treating substances by means of heat, so as to remove their brittlene and at the same time render them tough and more or le elastic. In general, these results are obtained by heating to a high temperature and then cooling very gradu annealing ally. All gla ware, china, etc., which is to be subjected to great changes of temperature should be thus treated. The working of iron and steel by hammering, bending, rolling, drawing, etc., tends to harden make them brittle, and the original properties are restored by annealing. Steel plates and dies for bank-note printing and the like are annealed in a close box with iron filings turnings, lime, or other substances, and are thus freed from carbon and reduced to pure soft iron, in which state they will readily take, under pre ure, the finest engraving from a hardened plate or die. They are then hardened again to the degree nece ary for their use in printing. Steel for engraving dies is commonly angalaually in dies annealed by heating a bed of charcoal. 2. Same as tempering.-3.
