Description:75x80mm 130oz Graphite Crucible Cup Propane Torch Melting Gold Silver CopperSpecification:          Material       Graphite           Outer size       75x80mm           Inner size            60x70mm               Features: High-density graphite crucible so that the crucible has the best thermal conductivity、 thermal conductivity better than other imported crucible. The graphite crucible and the appearance of a special glaze layer and forming a dense material、 greatly improving the corrosion resistance and prolong its service life. The graphite crucible graphite component used in all natural graphite、 thermal conductivity is very good. After heating the graphite crucible can not be immediately placed on a cold metal table、 due to a sharp cooling in order to avoid it being broken. Mainly used in the purification of gold and silver smelting、 metal casting special、 university experimental equipment、 acid corrosion of the crucible、 the crucible temperature analysis、 small scale casting、 special alloy smelting casting mold and so on.
