Product Description

 
 The graphite crucible, also known as molten copper and copper, is a kind of crucible made from graphite, clay, silica and wax. Graphite crucibles are mainly used to smelt copper, brass, gold, silver, zinc,lead and other non-ferrous metals and their arlloys.
 characteristics:
1. The high density of graphite crucible makes the crucible have the best thermal conductivity.
2. Graphite crucible has a special glaze layer and compact forming material, which greatly improves the corrosion resistance of the product and extends its service life.
3. All graphite elements in the graphite crucible are made of natural graphite, and the thermal conductivity is very good. The graphite crucible cannot be heated immediately on a cold metal desktop to prevent it from bursting with a sharp cooling.
