Powder used with alcohol to prevent firecoat on gold.
Safety Data Sheet
Boric acid is a fundamental chemical in the jewelry shop, most commonly mixed with denatured alcohol to create a protective "fire-coat" for gold and silver. When the alcohol is burned off, a thin layer of boric acid remains, preventing oxidation and fire-scale from forming during the soldering process.
This 5 lb box provides a substantial and economical supply for busy workshops and manufacturing facilities. It is an essential component for achieving the bright, clean surfaces required for high-quality jewelry and for minimizing the amount of finishing work needed after soldering.
