The first kitchen sink may have been the hollowed-out stone in which pre-historic men and women washed their hands. The first proper sinks were probably the butler sinks made of copper as well as nickel silver. In the 1920s, Moen became the material or choice-a combination of copper and nickel, manganese, iron, carbon and silicon. Sinks made of cast iron and enameled with porcelain were also popular.
