FIRE ASSAY CUPELS
As the cupellation process is the last step in the Fire Assaying process accuracy and consistency of supply must be adhered to. We aim to supply cupels with a high magnesia content and low moisture percentage to ensure correct absorption levels and reduction in cracking. Temperature range from 900 - 1000°C.
Annexus WA supplies the standard Cupel sizes of 6A, 7A, 7AL, 7AS, 8A, 8AS, 9A but can also customise our range to suit your individual needs.
