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 and flux or for crucible preparation and maintenance. Packaged in a one-pound (1 lb) box.

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

How to Use

1. Sprinkle a small amount into the crucible or onto the melt to create a protective layer.
2. For crucible conditioning, warm the crucible and rotate to coat interior surfaces.
3. 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 and crucible preparation. Borax is a naturally occurring mineral; boric acid is a refined derivative. Each can be used alone as flux, or mixed together to combine benefits for melting and crucible prep.

Use appropriate PPE, including gloves and eye protection. Avoid inhaling dust and keep the container closed when not in use. Follow foundry and crucible manufacturer recommendations for safe handling.
