The art of incrusting one metal on another, in the form of wire, which by undercutting and hammering is completely attached to the metal it ornaments. The process of etching slight ornaments on polished steel wares is also called damascening. Although related to pattern-welding, this technique used in the manufacture of sword blades probably developed independently. First a high-carbon steel is produced by firing wrought iron and wood together in a sealed crucible; the resulting steel, or wootz, consists of light cementations in a darker matrix, and this, together with a series of complicated forging techniques at relatively low temperatures produced the delicate 'watered silk' pattern with the alternating high- and low-carbon areas. Damascene steel was very strong and highly elastic.
