Notes

Borax vs. Boric Acid: They are two different formulations related to boron chemistry. Borax is a naturally occurring mineral used here as a casting flux; boric acid is a refined derivative. Both can be used during melting to help clean metal and may be mixed for certain shop practices, including crucible prep.

Care & Safety

• Use appropriate PPE (gloves, eye protection, fume management) when melting and pouring.
• Avoid inhalation of dust; keep container closed when not in use.
• Follow your foundry and crucible manufacturer’s recommendations.
