Fire Assay Crucible
Fire assay crucibles have a higher than normal resistency to cracking under fire assay conditions, used in laboratories. 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.
