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.
