Main material: 99.95% Graphite
Well corrosion resistance, impact resistance performance, to ensure the reliability of product quality.
Time-saving, good heat transfer performance of graphite crucible: for greatly shorten the melting time and save energy.

Utilization
Pure graphite will start to oxidize at 752 °F （400℃). The withstand temperatures can be 3200 °F if you use Air Electric Furnace.

Using Tips
Stored in dry place, do not get it wet
after drying the crucible , dont make it touch with water.
Be careful not to give a mechanical impact force, not from a fall or impact.
