Borax Flux Granular for Gold & Silver Melting – Jewelry Casting, Assaying, Soldering & Crucible Glazing – Removes Oxides & Improves Metal Flow – 5 lb

• ✔ KEEPS METAL CLEAN DURING MELTING High-quality borax flux designed to keep precious metals clean while melting and pouring. Helps reduce oxidation and protects molten metal during gold and silver casting.
• ✔ DISSOLVES OXIDES & IMPURITIES Borax creates a fluid borate slag that captures oxides and impurities on the surface of molten metal, improving metal purity and producing smoother pours.
• ✔ IDEAL FOR JEWELRY CASTING & MELTING Widely used by jewelers, goldsmiths, refiners, and metal casters for melting gold, silver, and other precious metals in crucibles and casting molds.
• ✔ PERFECT FOR CRUCIBLE GLAZING Essential for glazing ceramic crucibles before melting metal. The borax coating prevents molten metal from sticking to the crucible and extends crucible life.
• ✔ MULTIPURPOSE JEWELRY FLUX Granular borax can be mixed with water to form a paste used as a flux when soldering jewelry metals such as gold and silver, helping improve solder flow.
• ✔ LARGE 5 LB SUPPLY – EASY TO USE Granular formula dissolves easily and can be used dry or mixed into a paste. Packaged in a sealed clear plastic bag with a generous 5 lb supply for workshops and professional jewelers.
