Pewter

pu'ter, an alloy of four parts of tin with one of lead. Known also as Britannia metal. It stands more heat and is firmer than either metal alone. It is used chiefly for mugs, plates, and cheap tableware. An alloy known as plate-pewter consists of ninety parts of tin to eight parts antimony, and two parts each of bismuth and copper. Still a third pewter is composed of eighty-three parts tin and seventeen parts antimony.
