Quick Tips for Cleaner Casts
-
Pre-season new crucibles with a borax wash; this vitrifies the surface and prolongs life. View product »
-
Match capacity to batch size – avoid filling beyond 80 % to prevent spills.
-
Keep one crucible per alloy to prevent contamination, especially when working with platinum-group metals.
-
Use proper tongs or a support arm for steady, safe pours
Secure round or square crucibles at almost any angle. The heat-resistant steel arm tightens with a single thumbscrew and clamps directly to your bench or firebrick hearth, keeping both hands free for torch control and fluxing. Ideal for repetitive melts where precision pour height matters.
