    • 2.0 out of 5 stars If you want to melt cans, like I always do, look for something a little bigger
Size: 5kg graphite crucible
The cavity fits a standard soda can exactly which seems cool at first but the fit is so exact that if the can is crumpled at all it won't fit. A crushed can is a definite no-can-do... I can't go for that.

    • 1.0 out of 5 stars only buy if melting aluminum, because it won't last in higher temps
Size: 4kg graphite crucible
Product looks good but I burned a hole in it before I was able to melt any brass. It lasted about 3 minutes at 950 degrees Celsius. In addition, the side has warped in and i can't get all of my material out of it. If I could give zero stars, I would.

Didn't last through first firing. The crucible started to get smaller in top thickness and eventually fell into the electric furnace on its first run (after curing it). 1150C copper melt 1 KG
