• High Purity Graphite Crucible
  • 1PCS graphite crucible

Put the 2kg and 3kg models through their paces with Copper and Silver on an electric melting furnace, they retained heat well and no cracking / flaking thus far. Like any crucible, highly recommend seasoning it first, I do so by slowly raising the heat on it with it empty until I reach max usage temp and let it bake 30 minutes. Will be buying more.

Good product within the specifications listed in the photographics, not too much thermal expansion so even with a 1 mm tolerance it performs well. Be sure to check the inner chamber of compatible furnaces , mine has a temperature probe that slightly interferes as i bought the 3kg crucible, however it can still be adjusted and works as intended so this is no shortcoming of the crucible

Excellent little furnace. I’ve been melting anything I can get my hands on to pass time in the COVID lockdown and have not had any issues in 2 months. Been melting 4 or more times a week. Only wish it was larger.

Arrived in great condition.

Have one for Gold and one for Silver. Really heavy user for home refining. Works great

Great crucible at good price, last long.!! Fast shipping

Exactly as described. Will buy from them again.

Very nice crucible able to handle heating up past 1000 C multiple times.

I shall smelt me gold!
