摘要： A method of colouring the surface of a tin-containing article is provided, the method comprising contacting at least a portion of the surface of the article with a solution comprising a thiosulphate, preferably under substantially neutral or acidic conditions. In one embodiment, the solution contains sodium thiosulphate and citric acid and further comprises a copper salt, together with acetone and/or glycerol. The method is preferably conducted at elevated temperatures, in particular by heating the solution to a temperature of from 45 to 85° C. The method is particularly suitable for the colouring of pewter articles, but may be applied to a wide range of tin-containing materials and tin alloys.
