The brass and copper may be inlaid with gold and silver using a steal chisel, the artist first creates a groove in the surface of the brass, then hammers one end of the wire to fix it at the beginning of the groove, he continues hammering the wire along the groove until it occupies the whole space, he repeats this act in all neighboring grooves thus creating parallel lines of the precious metal. Using the other end of his hammer’s head he continues hammering parallel lines till the lines give the appearance of a flat piece of the precious metal as if welded to the brass, The artist may use the steal chisel to crave floral or geometrical decorations in the silver or gold surface
