Pure Graphite Crucible Cup Propane Torch Melting Gold Silver Copper Metal

Description:

Composition: 99.9% Graphite. Ash content less than 0.1%.
Excellent thermal conductivity and corrosion resistance. Better for Refining than Silicon Carbide Graphite Crucibles.
Performance: Excellent thermal stability for fast heating and cooling / Well corrosion resistance to strong acid and alkali / Good thermal conductivity properties which highly shorten the melting time and save energy / Great impact resistance performance to ensure the reliability of product quality.
Application: Melting and casting metals such as Gold, Silver, Brass, Aluminum, Copper, Zinc, Plumbum, etc.
Attention: Pure graphite crucible can NOT be heating by carbon furnace or charcoal kiln. It will be oxidized and cracked; Pure graphite will start to oxidize at 752 °F （400℃). The withstand temperatures can be 3200 °F if you use Air Electric Furnace. The withstand temperatures can be 5000 °F if you use Vacuum or Gas Protection Furnace.
