Works well. Have noticed that certain metals. IE Copper, Brass and silver sometimes takes the outermost layer of the crucible with it when cleaning.

I used the #5S a few times now, which holds more than the #6 by volume, while costing less, and melted aluminum in it to about ¼ inch from the top of the crucible. It performed as expected.Each crucible came with the same data sheet in the box the crucible came in. Both data sheets are for the #6 crucible and not for the #5S crucible. It would be nice to have the correct data sheet for the #5S crucible.Some of the reviews look like they don’t know how to use these clay graphite crucibles, because you do have to keep in mind they are made of clay. You can’t fill them with metal to be melted that is forced into the crucible, even a little bit, because as the metal as it heated it will expand. This expansion can crack and even break your crucible. Also don’t let the metal harden inside the crucible after a melt. Pour any remainder out into a ingot mold. They can’t take shock as well. Banging it on the ground will in time break the crucible. Treating these crucibles like they are made of clay should make them last a long time.Now after a melt and pouring the remainder in an ingot mold there will be a little metal left on the sides of the crucible, and the fact that it is made of graphite makes this easy to remove after it cools.

The crucible was smaller than I thought but it still works great! Definitely make sure to temper it before you start melting. I've been melting pop and beer cans with it and it works fine!

I upgraded to next day delivery and It was late by an additional day. The box was shipped in very sturdy container that was above quality compared to what I have gotten from other companies. Right out of the box there was several quality issues. There was a few DEEP gouges and cracks in the outer surface. You can tell they weren't caused from shipping related issues. They were def just lack of quality related. I haven't seasoned/cured it yet. I will update the review after usage.
