High performance, multi-use Fire Assay Crucibles AC2 – 65g (for an ore sample of 65g).
Upper diameter: 110mm
Inferior Diameter: 70mm
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.
