Common Applications for Starrbide Crucibles 

These crucibles are best-suited for processes that involve elevated rates of heating and fluctuating rates of temperature. 

Starrbide crucibles are also commonly used with furnaces that are induction-based or fuel-fired along with electric resistance heaters.

As they possess a high melting point and a strong degree of mechanical strength, they are valuable in the melting of heavy metal alloys and the holding of non-ferrous alloys.

Typical metal casting temperatures: 1300ºF - 2200ºF.

Best results are obtained by:

1) Gently pre-heating empty crucible until bright red on first melt to seal glaze.

2) Using a baseblock beneath the crucible to take the brunt of the burner's flame impingement.
