Zircon Value Price and Jewelry Information

Zircon is classed as high immediate or medium or low based on its level of deterioration These are also called alpha beta and gamma The classes are easy to distinguish because the properties change in an even progression High zircon

Zircon Crucibles

Zircon crucibles are also suitable for metal melting and casting since the cast metal does not stick to the crucible even at high temperature Zircon crucibles performs well with many nonferrous metals and alloys especially Aluminium Zircon is not “wetted” by Aluminium so is relatively unreactive 1550 C max service temperature
