GPK Premium Melting Flux 5 lbs
For Melting Metals and Basic Concentrates
GPK Premium Melting Flux is a custom mixed formulation
for melting Silver, Gold, Copper and smelting basic ore concentrates.
GPK Premium Melting flux is a mild go to flux that is designed to melt metals
for casting and smelting basic concentrates.
GPK Premium Melting Flux has been specifically developed for
melting Silver, Copper and Gold for casting ingots. Black fluxes adhere to Silver
and Copper ingot castings and are difficult to remove due to the oxidizing properties
of them. GPK Premium Melting Flux is a balanced flux that is removed
easily from cast ingots and is not as acidic as plain anhydrous borax.
When smelting basic concentrates it readily allows contained metals to reduce for
it's a great flux for finding out what's in your concentrate
without the worry of vaporizing it. GPK Premium Melting Flux performs well
with Fused Silica, Graphite, Clay Graphite and Fire Clay Crucibles
with minimal corrosion occurring during their use.
