White Metal
The white metals are any of several light-colored alloys used as a base for plated silverware, ornaments or novelties, as well as any of several lead-based or tin-based alloys used for things like bearings, jewellery, miniature figures, fusible plugs, some medals and metal type.
Some of the metals that make up a white metal alloy are antimony, tin, lead, cadmium, bismuth, and zinc. Not all of these metals are found in all white metal alloys but are mixed to achieve a desired goal or need. As an example, a base metal for jewelry needs to be castable, polishable, have good flow characteristics, have the ability to cast fine detail without an excessive amount of porosity and cast at between 230 °C and 300 °C (450 °F and 575 °F).
In compliance with British law, the British fine art trade uses the term "white metal" in auction catalogues to describe foreign silver items which do not carry British Assay Office marks, but which are nonetheless understood to be silver and are priced accordingly.

Famous quotes containing the words white and/or metal:
“I am black: I am the incarnation of a complete fusion with the world, an intuitive understanding of the earth, an abandonment of my ego in the heart of the cosmos, and no white man, no matter how intelligent he may be, can ever understand Louis Armstrong and the music of the Congo.”
—Frantz Fanon (1925–1961)
“And, indeed, is there not something holy about a great kitchen?... The scoured gleam of row upon row of metal vessels dangling from hooks or reposing on their shelves till needed with the air of so many chalices waiting for the celebration of the sacrament of food. And the range like an altar, yes, before which my mother bowed in perpetual homage, a fringe of sweat upon her upper lip and the fire glowing in her cheeks.”
—Angela Carter (1940–1992)
