Combinaison, union de deux ou plusieurs éléments.
ETYM French amalgame, prob. from Latin malagma, Greek malagma, emollient, plaster, poultice.
Alloy of mercury and another metal, especially silver, used to fill teeth; blend.
Any alloy of mercury with other metals. Most metals will form amalgams, except iron and platinum. Amalgam is used in dentistry for filling teeth, and usually contains copper, silver, and zinc as the main alloying ingredients. This amalgam is pliable when first mixed and then sets hard, but the mercury leaches out and may cause a type of heavy-metal poisoning.
Amalgamation, the process of forming an amalgam, is a technique sometimes used to extract gold and silver from their ores. The ores are treated with mercury, which combines with the precious metals.
1. A combination or blend of diverse things.
2. An alloy of metal with another metal (usually silver) used by dentists to fill cavities in teeth; SYN. dental amalgam.
