    Great Alloy For Casting Mineral Crystals

    Posted by Raymond Karpinski on Feb 28th 2022

    Using this alloy to cast mineral crystal at low temperatures to minimize heat damage to the mineral structure. This Alloy works great and doesn't produce any slag.

    Bismuth for lead free projectiles

    Posted by Lawrence on Jan 24th 2020

    In California expanding lead free projectiles are the only thing used. My dilemma was being able to harvest with my father’s .54 cap lock Rifle. I am sure this product will expand on impact, even a thousandth and the big ball will do the rest at 50 yards. Great deal allowed me to let me use with my many old guns. Curio relic are my favorite. Thanks

    Works well as low-temp solder for chip removal

    Using ROTO203F as a low-temp solder for chip removal, works well for that application.
