Mokume-gane (木目金) is a Japanese metalworking procedure which produces a mixed-metal laminate with distinctive layered patterns; the term is also used to refer to the resulting laminate itself. The term mokume-gane translates closely to 'wood grain metal' or 'wood eye metal' and describes the way metal takes on the appearance of natural wood grain. Mokume-gane fuses several layers of differently coloured precious metals together to form a sandwich of alloys called a "billet." The billet is then manipulated in such a way that a pattern resembling wood grain emerges over its surface. Numerous ways of working mokume-gane create diverse patterns. Once the metal has been rolled into a sheet or bar, several techniques are used to produce a range of effects.

Old Sheffield Plate is the name generally given to the material developed by Thomas Boulsover in the 1740s, a fusion of copper and silver which could be made into a range of items normally made in solid silver. The material rapidly gained popularity as a substitute for solid silver, as it was much cheaper to produce. Any object made in silver could in effect be made in Old Sheffield Plate, although objects subject to heavy wear such as spoons and forks were not so satisfactory in plate.
