Nisorpa 6KG Silicon Graphite Crucibles for Melting Metal, Foundry Silicon Carbide Clay Crucible Cup, for Gold Silver Copper Brass Aluminum Melting Casting Refining

Does the job with a good price tag!

Used this for a small backyard foundry and it worked great with a gas and coal. I'm not sure how low it would last with just coal but worked fine a few times until I got the gas foundry working. Time will tell if its going to last. Very pleased so far!

I heat cycled this little guy and so far it's hanging in there. Even expensive crucibles need to be seasoned this way before use. After cooling and inspection there was no damage. Next step will be making bronze!

Works perfectly so far, I've used it about just 3 times now to melt aluminum cans in my home made mini foundry. It gets glowing hot and hasn't cracked or broken yet.

This is the only crucible i have found that doesnt break after a couple fires! I have now done 16 and its still going strong! Thank you

The media could not be loaded.  The packaging was great. As I removed all the bubble wrap I realized that the quality of the crucible was poor. The top brim is uneven and warped. The coating is uneven, bubbling, running, and in some places not there. The bottom of the crucible has a big lump running across the middle which does not allow it to sit flat. Which allows it rock back-and-forth and tip which is the last thing I wanna have molten metal in. I thought by paying almost double the price then another crucibles I would get better quality but I guess I was wrong.

It's a beast, 12 runs no cracks yet, using a 500000 btu weed torch, amazing product

High quality crucible at a good price!
