Agate is a semi-precious stone, which consists of certain siliceous materials. There are different kinds of colourings of agate. Each colour looks different and is therefore unique. The burnishers are suitable for all leaf metals that can be processed with the poliment gilding technique. Because the polishing stones are highly sensitive, it is recommended to keep them away from hard surfaces to avoid them getting scratched.
This burnisher #17 is the most used by gilders, you can burnish almost any gilded surface with it. Other shapes and sizes are also available on back-order.
