Melting Crucible is mostly used for melting precious metals, such as Gold, Silver, Bronze, Copper, Brass and more.
Crucible Capacity is 40 T.oz./1200 Grams, made of clay bonded high grade fused silica, long lasting "A-1 QUALITY" withstands temperatures up to 2500°F / 1371°C.
Assay crucible can also be called melting gold crucible, gold alchemy crucible, clay crucible, clay mullite crucible, intermediate frequency crucible.
Product features: high refractoriness, good corrosion resistance, no slagging, no penetration, no cracking, no gold and silver elements can make the test results more accurate, it is the first-class equipment for fire assays, and does not deform when heated at high temperatures Or collapse, can maintain sufficient strength at high temperature, will not break when tongs or fork out, can resist the erosion of the melt, ensure that the crucible does not leak, use it for 5 times, it will not burst, the refractoriness is 1600 degrees, and the load is softened Temperature 1400 degrees.
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.
