Boric Acid Powder-1Lb

Boric Acid (technical grade) powder functions as a high-grade casting flux and deoxidizing agent to help keep metal clean during melting and pouring. Use as a general casting powder/flux or for crucible preparation. Packaged in a one pound (1 lb) box.

Key Features

• Controls oxidation during melting and casting
• Helps produce cleaner pours with fewer inclusions
• Use alone or mix with borax for tailored flux behavior
• Suitable for crucible prep and maintenance

Specifications

How to Use

• Sprinkle a small amount into the crucible or onto the melt to create a protective layer.
• For crucible conditioning, warm the crucible and rotate to coat interior surfaces.
• Blend with borax (as needed) to adjust flow, wetting, and oxidation control.

Notes

Borax vs. Boric Acid: Both are related boron compounds used in melting. Borax is a naturally occurring mineral; boric acid is a refined derivative. Each can be used alone as flux, or mixed together for melting and crucible prep to combine benefits.
