hardening something by heat treatment
The act of heating solid metal or glass to high temperatures and cooling it slowly so that its particles arrange into a defined lattice.
Without annealing, the quality of our metal products will diminish.
the process used to render glass, iron, etc., less brittle, performed by allowing them to cool very gradually from a high heat
the burning of metallic colors into glass, earthenware, etc
Annealing, in metallurgy and materials science, is a heat treatment that alters a material to increase its ductility and to make it more workable. It involves heating material to above its critical temperature, maintaining a suitable temperature, and then cooling. Annealing can induce ductility, soften material, relieve internal stresses, refine the structure by making it homogeneous, and improve cold working properties. In the cases of copper, steel, silver, and brass, this process is performed by heating the material for a while and then letting it cool to room temperature in still air. Unlike ferrous metals—which must be cooled slowly to anneal—copper, silver and brass can be cooled slowly in air, or quickly by quenching in water. In this fashion, the metal is softened and prepared for further work—such as shaping, stamping, or forming.
