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 a microwave kiln.)
Flux is weighed into doubled 4 mil bags for USPS Priority
shipping.
