Features:

The graphite crucible has good thermal stability, suitable for emergency heat or cold usage condition.
Good corrosion resistance and impact resistance.
Excellent acids resistance and alkalis resistance.
The graphite crucible has good thermal conductivity properties,it can greatly shorten the melting for time and saved energy.
The ashes of graphite crucible is less than 0.1%,to ensure that the in the smelting is not contaminated.
It can melt gold, silver, and other precious metals and other alloys,with long service life.
you can select the size you need, and the size you can find on the listing photo
for gold and silver melting after the formation of gold and silver pieces
can also be used as graphite crucible melting into non-ferrous metals, test analysis, as the ingot mold and other purposes.

Size for manual measurement, there may be a 0 to 2 for cm error, belongs to the normal phenomenon.
And due to the difference between different monitors, the picture may not reflect the actual color of the item.

Thank you!
