Boric Acid Deoxidizing Casting Flux for Melting Precious Metals

Introducing Boric Acid Deoxidizing Casting Flux, a high-grade, ultra-fine flux that keeps metals cleaner during melts and pours. This Boric Acid Deoxidizing Casting Flux provides oxidation protection and helps achieve brighter finishes across precious metals. Ideal for melting, casting, and refining gold, silver, copper, iron, sterling silver, tin, nickel, and their alloys. It also acts as an antioxidant in soldering and helps reduce dross. Proudly made in the U.S.A.

Designed for reliable performance in professional and hobby metalworking, this flux helps keep melts uniform and reduces the risk of oxidation that can affect color and integrity of your castings. Compatible with refining workflows and easy to dose for consistent results across batches.

• High-grade, ultra-fine formula for cleaner melts and improved pour quality.
• Wide metal compatibility suitable for gold, silver, copper, nickel, tin, and alloys.
• Antioxidant in soldering to minimize oxidation during joins.
• Efficient dross suppression for more consistent refining results.
• Made in the USA for quality and reliability.
