A whitesmith or tinsmith is a person who makes and repairs things made of tinware. By extension it can also refer to the person who deals in tinware. A whitesmith may work with tin, pewter, or other materials. Unlike blacksmiths (who work mostly with hot metal), tinsmiths do the majority of their work on cold metal (although they might use a hearth to heat and help shape their raw materials). The term is also applied to metalworkers who do only finishing work – such as filing or polishing – on iron and other "black" metals. Whitesmiths fabricate items such as tin or pewter cups, water pitchers, forks, spoons, and candle holders and it was a common occupation in pre-industrial times.
