6 OZ Assay Dense Soda Ash
The 6 OZ Assay Dense Soda Ash is a premium assaying flux used for melting and smelting precious metals in both hobbyist and professional refining. This Sodium Carbonate-based flux, also known as assay dense soda ash, acts as a flux thinner to improve fluidity, slag control, and button formation during gold processing.
Ideal for gold recovery from black sands and bench grinds, this versatile flux can be used on its own or blended into your own flux recipe. Its consistent density supports even heat distribution, reduces impurities, and helps yield cleaner bullion.
Also known for its stable chemistry, the sodium carbonate formulation delivers predictable performance across a range of crucible and furnace conditions. Use it to enhance metal recovery while maintaining easier fluxing and clean separations.
