Product Details
Refine and assay gold with ease using DECENT Magnesia Bullion Blocks
Magnesia Bullion Block is a shallow, porous block with multiple holes, made from pure Magnesite, in which gold or silver can be refined or assayed by melting with a blast of hot air which oxidizes lead or other base metals.
[ Advantages ]
• Great mechanical strength, and are not affected by atmospheric conditions (not hygroscopic).• The prill or bead does not adhere to the fire assay cupel surface,
• When using DECENT magnesia bullion blocks, the assay has a reduced tendency to freeze.
• No cracking or spiting, and the beads do not attach to the fire assay cupel surface.
• DECENT magnesia cupels provide security and quickly absorb great amounts of litharge without cracking or pitting.
• Our magnesia bullion blocks allow for reducing the Cupellation temperature and time, resulting in minimal losses, higher accuracy and better yields.
• Perfect uniformity of Quality of DECENT magnesia bullion blocks
• Quality and performance are continuously improved
[ Features ]
• Made of high-quality magnesia, Bone Ash, etc.• High casting density.
• With extremely low Gold and silver content, can get more accurate test results,
• Widely Used for smelting and assaying
• High-temperature resistance and resistance to thermal shock
• Can be used 3-5 times for the crucibles for fire assay.
• Free samples are available.
