Description

An old French term for potter's clay, the word lute has long been used to describe putty or adhesive materials that seal a surface or joint and make it waterproof. Lutes are usually composed of cement, mud, plaster, or clay. The Romans used a clay cement to set iron posts into stone. Plumber's lute is a mixture of plaster with a weak glue binder. Pipe clay mixed with linseed oil is called fat lute. Litharge cement has also been used as luting. Spence's metal is a mixture of metals sulfides that is used to seal pipe joints. Lute cements are still used as acid-resistant materials for bonding ceramics to metals and for adhering knife blades to handles.
