FORGING is a method of deforming metal with a hammer on an anvil. In the case of Sterling Silver and the Karat Golds, this must be done COLD! If a hot forging is attempted the precious metals will just crumble. In their PURE form Silver and Gold will allow HOT forging, but there is no benefit to be gained. Wal.
Répoussé is a method of sheet metal forming where the metal is placed on a bowl of softish pitch. The metal is then hit down into the pitch with smooth punches. If the desired result needs greater depth or more refining, the work may be turned over and worked from the other side. The pitch supports the metal where it is not being hit, and in this way three dimensional shapes of great depth can be achieved. Some confusion exists in the English speaking world, because the word "CHASING" is used for two different techniques. In German the word for chasing, is zisellieren, or chiselling. The object to be decorated is placed on a quite hard "chasers pitch", and is then worked with small cutting punches. the look is somewhat like engraving. Wal.
