Cupel is a porous refractory for absorbing lead oxide when ash blows the lead buckle. The main component of magnesia is magnesium oxide, which is a very good refractory and can resist the erosion of alkaline flux. Lead oxide is a very strong alkaline flux. At high temperatures, the affinity between lead oxide and silica is very strong, which can invade the silicate in the cupel. There is more silicate in the ash cupel and cement cupel. After blowing with this kind of cupel, there will be pits on the surface of the cupel, and precious metals will be lost as a result. Using magnesia cupel, no such phenomenon after ash blowing, the surface is very smooth.
Cupels are magnesia or bone ash cup shaped containers used in assaying to separate precious metals from base elements such as lead. They operate as a "differential filter" and are porous to metal oxides, but not metals. Used in an oxidizing atmosphere, base metals are oxidized and are absorbed into the cupel. Since precious metals do not oxidize, they are not absorbed and are left on top of the cupel for weighing or further analysis.
Cupels should not crack when heated in the muffle and should be so strong that they will not break when handled with the tongs. Good cupels give, a slight metallic ring when struck together after air-drying. It is best to heat cupels slowly in the muffle as this lessens the chance of their cracking.
This small shallow porous Cupel is manufactured from bone ash, a composite material and Magnesite (MgO). Used in assaying to absorb separate precious metals from lead.
Our magnesia cupel uses high-quality raw materials and a unique formula. And its composition includes up to 96% magnesium oxide and special flux. Our magnesia cupel absorbs more lead oxide than ordinary bone ash cupels. So our magnesia cupel has strong mechanical strength and perfect quality uniformity.
