Review: Perfect for my Mini Metal Foundry!!! - Mini Metal Foundry crucible. I bought this for Grant Thompson's 'Mini-Metal Foundry'. It fits perfect!. I have been melting holes into my stainless steel homemade crucibles and this is a serious upgrade. Note for shipping: this is not on Prime, but I ordered it Monday night and it arrived Thursday morning... fabulous! Pour spout: I have seen negative reviews about the dimple for pouring, or lack there of... mine came with a perfect pouring dimple in it... check out my pics. Size: I did not use the expensive plastic containers Grant had listed to build the interior of the foundry. I bought similar sized ones from the dollar store... WIN!!! Same with the containers to form the lid. You just have to understand the basic principle of how much space you need and then purchase a container that will suffice. I even found the stainless steel dish scrubbers (for added structural integrity... you need it) at the Dollar store. All that to say, I have just a hair more space on the inside of my foundry than Grant does, therefore, this crucible fits perfectly and I can get charcoal all around it. I'm not sure how tight it would be If I had bought the expensive blue buckets he had listed. I also purchased a little container from the Dollar store to act as the feeding hole in the lid... saves the time of having to cut one with the hole saw, and it's a lot less messy... check out my pics. If you have any questions, give me a shout, I have built 2 of these guys and had great success. Make sure you pre heat it a lot... I fired up the Foundry and kept the heat low... did this 3 times.
Review: Would buy again - This crucible does everything I need it to. I think it’s probably a 4KG crucible but can’t say for sure. I made sure to heat it in the oven at 300° F for an hr to get any moisture out of it and then temper it By heating it in the foundry to red hot and letting it cool in the foundry as slow as possible all night before use to avoid the crucible from breaking. So far I’ve done about 5 melts of copper and brass in it and it’s held up just fine at temperatures of probably over 2000° F. For the $20 it does everything it needs to very well. Would definitely buy again.

## Questions & Answers

**Q: Will this work with Grant Thompson's mini metal foundry?**
A: Yes. I made a slightly larger build (6 gal bucket) and it holds up to the heat of this "big brother" version. Others have stated that this one will in fact fit the smaller 10 quart build. So I wont refute that.  This is also effectively the smallest size of this line of crucible that will properly hold a 12 oz soda can fully in its mouth so that it will melt. One Down side to it is that large of a bucket ends up needing a LOT of fuel compared to a smaller likely more efficient build. I use this crucible and it can even withstand the heat of using anthracite instead of a charcoal fuel source which seems to compensate for the huge nearly 2 inch gap from outer crucible wall to inner foundry wall. This crucible stood up to the heat, even when the crucible itself was slightly glowing red. The downside this one has compared to the suggested depleted steel fire extinguisher crucible is the thickness of this one seemingly takes longer to transfer the heat to the media being melted. Again anthracite compensates, but it takes more time, more work and more fuel to get my build using this crucible going, but once it does, it runs like a diesel fueled freight train. You can practically melt a can as quickly as you can drop them in.One thing to be wary of, This crucible would be much nicer and safer if there were some sort of gripping ring/ledge near the top for tongs to lock into. So be very careful when pouring. You will spill, You will waste, and sometimes you will end up with half a crucible full of slag that splashes into your perfectly shaped biscuit. Its cone shape is NOT ideal for handling this much aluminum weight with accuracy.One thing to also note, So far it has been my experience that this takes roughly 20-30 cans to fill (to a safe level) which will yield around a quarter pound ignot muffin and the remainder will end up as slag. Ballpark estimate, One 13 gallon trash bag full of un crushed cans will yeild roughly 1 lb of pure aluminum and the remainder as slag. This is just my lay math, YMMV.

**Q: How big is this basin, compare it to something? Wanting to sand cast aluminum rods.**
A: It will hold 3 lbs of molten aluminum (that's its rating) about the size of a large can of tomatoes according to my husband

**Q: `Can you get enough heat generated in a kettle grill with coals to melt aluminum cans with this?**
A: I am using a home  made foundry but I use your normal grill coals to melt cans with, I find it better then the hard wood coals actually.

**Q: Can you quote the approximate physical dimensions (height, and outer diameter at top) please.**
A: Dimensions: Outer - 5.25" H x 4.75" Dia. Inner - 4.75" Depth x 3.75" Dia. (Inner). The inside dimensions are a rounded cone, not a cylinder. The size for this crucible is 4 KG (4 Kilograms of Brass.) If you convert 4 KG of Brass the volume of this is 28.7247 cubic inches or a 3.7997 inch Ball or Sphere. Here are examples of the sizes of Crucibles:1 KG = 7.1812 cubic inches = 2.3936" Sphere2 KG = 14.3624 cubic inches = 3.0158" Sphere4 KG = 28.7247 cubic inches = 3.7997" Sphere6 KG = 43.0871 cubic inches = 4.3496" Sphere8 KG = 57.4494 cubic inches = 4.7874" Sphere10 KG = 71.8118 cubic inches = 5.1570" Sphere12 KG = 86.1742 cubic inches = 5.4802 Sphere14 KG = 100.5365 cubic inches = 5.7691 Sphere16 KG = 114.8989 cubic inches = 6.0317 Sphere

### ⭐⭐⭐⭐⭐ Buy the correct size
*by Z***N on February 16, 2026*

Pretty sturdy up until copper melting temperatures. Decent value for money. You're buying the size that you get 2. Kilograms is not that big but enough to melt cans.
