I'm taking a class in making mokume gane, a Japanese metal painting technique that requires a lot of metal cleaning. I got this brush to clean lots and lots of copper, silver and nickel sheets. . This brush might be too big for some pieces and one reviewer said the bristles fall out, but I bought this brush for such a good price that I'm happy even if it only lasts a semester of jewelry making! The large thick handle fits well in my hand. Smaller brushes increase hand fatigue.
