WEBGraphite Crucibles. Graphite crucibles are high quality melting crucibles. They can be used at temperatures up to 1600C (3000 o F) and are suitable for melting and refining precious metals, base metals, and other products. Use proper flux, and be sure to preheat the crucible prior to the first use to drive off any residual or accumulated moisture.
