Absolutely a good bang for the buck. Works exactly as advertised. Super easy to use gets hot quick. Melts metal. You need a long slag stick and all the PPE... the gloves are not long enough or thick enough but I wasn't buying it for the gloves. Outstanding

I am impressed with this little furnace kit. It worked really well for the first burn and was easy to set up. It reaches melting point fairly quickly. My only real complaints are that the ceramic honeycomb tile was broken when it arrived and that the kit says it has everything needed (which it mostly does) but a set of pouring tongs would have been nice. Overall, I am happy with my purchase. I would change it to five stars if the seller replaces the broken tile.

Great product! I did not have the heat turned up all the way and it melted a large piece of aluminum in less than 5 minutes. The size is perfect for the size of the ingot mold I was using The only negative I have is the gloves that were part of the kit. They were terrible. The tips of them burned through. I suggest purchasing a good set of leather welding gloves or a good pair of firefighters gloves.

I bought a different single burner furnace gist and I was out side for hours trying to melt a small amount of copper and it didn't happen. I purchased this furnace and it melted the copper fast. I melted two bars in und 2 hours

Foundry is great but the crucible they sent with it was broke and the only way to get replacement is to send the entire thing back

OK, I have tinkered with this for multiple hours and figured out eventually how to make this thing work properly when you go to light the flame I would suggest taking a small stick or a piece of paper and putting it inside the actual container, then slowly turn the flame on, you will hear a small Roaring noise and that’s (the tornado flame). Then slowly turn the gas up until you reach kind of almost all the way open, DO NOT do this inside, have patience and eventually it will start to glow hot red. I also noticed these are the WRONG tongs, they are good quality but the wrong size, the gloves are alright, for the price it is good, also they need to add better instructions, not for putting it together but for how to safely light it etc.
