Product Description

 

Magnesite Cupel Bone Ash Cupel Used in Laboratory
Cupellation is the last and most important step in fire assay process and as such, the quality of cupel is extremely crucial.

During cupellation, the lead is oxidized to litharge (PbO), most of which is absorbed by the cupel. Gold, silver, platinum and other precious metals form a bead in the cupel. The bead is subsequently treated to determine its precious metal content.

Our magnesia cupel uses high-quality raw materials and a unique formula. And its composition includes up to 95% magnesium oxide and special flux. It can absorb more lead oxide than ordinary bone ash ones. So our magnesia cupel has strong mechanical strength and perfect quality uniformity.

Our Advantages

High quality magnesite is the majoritary component of  magnesia cupels. 
As a rule of thumb, magnesia cupels have a superior quality and offer many advantages:

  1. Great mechanical strength, and are not affected by atmospheric conditions (not hygroscopic). . 
  2. The prill or bead does not adhere to the fire assay cupel surface, 
  3. When using magnesia cupels, the assay have a reduced tendency to freeze.  
  4. No cracking or spiting, and the beads do not attach to the fire assay cupel surface.
  5. Magnesia cupels provide security and quickly absorb great amounts of litharge without cracking or pitting. 
  6. Our magnesia cupels allow to reduce the Cupellation temperature and time, resulting in minimal losses, higher accuracy and better yields.
  7. Perfect uniformity of Quality of cupels 
  8.  Quality and performance are continuously improved
