Premier Copper Products' Old World copper vessel sinks are hand-forged from one solid block of copper, giving each model a one-of-a-kind look. The blocks are beaten flat by five men who stand in a circle around the copper, taking turns to hit it with a hammer until the desired thickness is reached. By using this technique, only two sinks can be made each day. Offered in several different shapes, the sinks range in size from 15 in. to 20 in. wide.
