Good quality

Great crucible, incredible price. exactly what I wanted. They're the perfect size for melting pop cans and all the chunks of copper and brass . Fits one can at a time perfectly. very durable. Have done about 6 melting’s with it so far, and it is still in like new. “”Definitely would buy another one if need it”” . These graphite’s are great quality . wear gloves when you handle these since your hand can be grey stained . but in the several pouring’s I've done so far it's worked perfectly.

so one thing to always remember and that is to temper the crucible as not doing this will possibly cause the crucible to fail so if done then your good to go as this crubile already worked great on 3 big copper melts and still looks great

I got 2 crucible one from Amazon and one from a local jeweler supplier and the one on the left is the Amazon bought and the one on the right is jewelry supply store it has discoloured.
