CANALHOUT 12.3KG Silicon Carbide Graphite Crucibles,Crucibles for Melting Metal,Withstand The High Temperature 1800℃(3272°F),Melting Casting Refining Aluminum Gold Silver Copper

Good quality. Able to be used for many more firings than regular carbon.

Good product delivered on time as described

These are good crucibles, but be warned, they do not hold the rated volume. I have two of the sizes, I have the No.3 and the No.5s. The No.3 crucible is rated at 400 mL volume, but its actual volume is only about 260 mL. The No.5s is rated at 775 mL, and I measured it in at about 500 mL. They are about 35% short of what their rated volume is, so just be warned, if you need a specific volume, multiply the rated volume by 0.65, and that will give you a close estimate of what the actual volume is. Other than that, they last a decent amount of time, I don’t cast that often, maybe three or four times a month, but they lasted me just over two years.

These work great, very happy!

Robust build and lasts thru many firings

Works great and much easier to handel than the 10 kg ones that came with my forge

The media could not be loaded. These crucibles work great, better than great, closer to jaw dropping astonishing. Like seeing a pig fly. No cracking, no residue sticks and pours smoothly. Very easy to clean if at sll necessary(so far not at all), I even dumped a bunch of borax and random river gravel just to really test one. It all popped out after it cooled few minutes. I've had borax eat a few crusibles. Amazing product, keep up the great work. 10 out of 20 💯% recommended. Oh I don't recommend the borax and gravel thing I did incase one or more stones explode from the rise in temperature.

Retains heat efficiently and holds up well after multiple uses. A little smaller than expected, but overall great quality and durability!"
