These fire assay crucibles provide erosion and cracking resistance under harsh working conditions (up to 1300ºC). Universal Fire  Assay Crucibles yield longer life, faster fusion, constant melting speed and resistance to thermal shock.

The material of construction is high quality refractory fire clay with high alumina content that makes them resistant to litharge attack.
