An all-purpose flux, consisting of Sodium Tetraborate (Anhydrous Borax), Sodium Carbonate (Soda Ash) and Silica Sand. Great for melting pure precious metals, such as gold, silver or copper, or smelting silver ore concentrates. Also works great with gold concentrates that have silver or copper in them that you wish to save (you will end up with an amalgam of precious metals). Especially developed for Kwik Kilns® but also works well with other furnaces (Not for use inside the microwave kiln.)
