Foundry Crucible for Gold Smelting

Clay fire assay ceramic crucible
Fire Assay Crucibles have a higher than normal resistency to cracking under fire assay conditions. Our crucibles
and refractory products are used in laboratories throughout international marketplace. We have a variety of shapes
and sizes available to cater to specifications required.
Our crucibles give longer life, faster melting, constant melting speed and exceptional resistance to violent changes
of temperature.
