Good for small amounts of material
Appears to be a decent crucible and it will do the job nicely. If you are looking to do large quantities of material this isn't for you. With that said the crucible has thick walls and came well packaged.

Exactly 40mm long and 40mm in diameter
I am very pleased with this product. The workmanship is of high quality. There are no inclusions, abrasions, scrapes or defects. The lid aligns flush with the top of the crucible, without gaps. The lid is not tight - it does slide a little bit... but the play is less than a half milimeter. That is good, because it means it will not get stuck into the crucible. This product is exactly as described, 40mm high and 40mm diameter. 40mm is 4cm. This translates to 1.57 inches...

Graphite crucible. Worked as expected.
Used for melting gold nuggets. Did exactly what I needed it to do.

Great little crucible for melting silver
Iโve have bought quite a few of these in the last 6 months. I use them to melt silver in a propane furnace where they are directly exposed to a torch flame for about 10 minute at a time. They generally last about 20 times before the graphite degrades enough to start having holes in the side. The max silver I have done in this is crucible about 6 Troy ounces leaving about 1/4 inch at the top. Overall for the price these things are hard to beat and Iโll continue to buy more!
