9 Oz Anhydrous Borax Deoxidizing Casting Flux for Melting Precious Metals

Experience cleaner melts and reliable pours with our 9 oz anhydrous borax deoxidizing casting coarse powder flux. This borax flux for melting precious metals minimizes oxide build-up and slag, helping you achieve brighter, purer ingots. Its coarse formula also assists in seasoning graphite crucibles and maintaining pristine surfaces for repeated use across gold, silver, copper, iron, nickel, tin, sterling silver, and their alloys.

Designed for both professionals and hobbyists, the flux integrates easily into your melting routine and delivers consistent results from pour to pour.

• Coarse, anhydrous formula for rapid oxide removal during high-temperature melts.
• Deoxidizing action minimizes oxygen uptake and slag formation.
• Multi-metal compatibility suitable for gold, silver, copper, iron, nickel, tin, and alloys.
• Crucible seasoning aid helps extend the life of graphite crucibles.
• Cleaner pours yields brighter ingots with fewer impurities.

Usage at a glance: sprinkle a small amount into the melt when temperatures rise, then proceed with your usual refining steps. Store in a cool, dry place to preserve performance.
