chaser แปลว่า

""Mr B., heraldic chaser, says there are several processes in making heraldy plates, sketching, engraving, embossing, chasing and burnishing." "H. & C., manufacturers of cloth and gilt buttons, say it requires some weeks to learn to chase the gilt buttons, which are done with small metal tools and a hammer. Chasers are paid by the piece, working ten hours a day, and some can earn $1 a day.""

""Flat chasing in sunken or low relief is a technique by which the ornament is formed by beating down the ground from the front. This is done in essentially the same manner as repoussé work, where the ornament appears in high relief, but the design is punched from the face of the silver plate. ... Sometimes, instead of applying a freehand design, the chaser covers the greased surface with a paper pattern in which the design is pricked with pins.""

""Chasing in general can be distinguished from engraving, in that the design can be seen on the reverse or inside of the pieces. Having outlined the pattern on the surface, the chaser cuts and at the same time slightly depresses the surface. A light hammer can be used in this process also.""
