AMAZING
Size: # 5S
i got the #5s and it works so well for cans, i melted about 100 cans and got 2 pounds of aluminum, it is very easy to clean and you don’t even need a furnace i just put it in a normal fire.

Nice crucible. Seems high quality
Size: # 3
I use this for aluminum exclusively and it’s holding up well after about 50 pours. Starting to show some signs of degradation but that is expected. Make sure to properly treat the crucible before first use.

Works Great:
Size: # 6
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.
