Century Dictionary and Cyclopedia
- n. The act or art of testing metals, ores, or alloys in order to ascertain the quantity of gold or silver or any other metal present in them. There are two modes of assaying, one of which is sometimes employed to corroborate the other. The one is called the humid or wet process, in which the solution of the metals is effected by means of acids, after which those sought for are precipitated by proper reagents. The other is called the dry process, and is performed by the agency of fire. The first is generally employed for the purpose of estimating the quantity of gold or silver in an alloy, and the second is chiefly applied to ores. Tests are also made by comparison of specific gravities, and by the color of the streak or trace made by rubbing the ore upon a rough surface. In Great Britain each article of silver or gold plate is assayed at Goldsmiths Hall previously to being sold, in order to determine the exact richness of the metal of which it is made. See
hall-mark . - n. In chem., this term is usually applied to the ascertainment of the presence and amount of one or more metals in a given substance, and commonly refers to the precious metals, gold and silver. But it is sometimes used in the more general sense, the testing or examination of any substance, as, for example, the determination of the proportion of pure sulphur in a sample of the crude material.
