ENCHASING, or CHASING, the art of embossing or making figures in low relief upon gold, silver, and other metals. It is practised only on hollow thin works, such as watch-cases, tankards, cups, &c. The design having been traced on the exterior surface of the metal, the work is hammered upon steel blocks or punchcons introduced within; and thus the workman proceeds to indent the metal by the successive application of the block and hammer to the several parts of the design; after which the work is cleared with small chisels and gravers. In this simple manner a skillful artist is able to represent foliage, figures, &c. with admirable precision.
