## Customer Reviews

### ⭐⭐⭐⭐⭐ Qualty product
*by D***) on January 24, 2026*

Well made and good shipping/packing

### ⭐⭐⭐⭐⭐ 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
*by J***A on January 8, 2018*

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...
