Summary: Great way to get started in metal casting, does require minor assembly and operation does take a little finesse since there isn't a regulator. Overall the kit has everything you need to start casting metal, though I would recommend some leather welding gloves and a fire extinguisher. The furnace is better than most, with a refractory cement interior and the only exposed Kaolite being on the lid - Kaolite becomes extremely brittle even after a single firing, so this makes it a lot more durable than cheaper furnaces which have exposed kaolite on the interior of the burn chamber The furnace was well-packaged with tons of bubble wrap and arrived with no damage. Design, fit and finish, assembly are basic and functional - for example the feet are simply nuts welded to the outer shell, but serve their purpose. I do like that the top of the furnace is slightly tapered to make a tighter seal with the lid, although the hinge for the lid could definitely be beefier. Crucible and ingot mold are decent - both are graphite so should last a long time, though I wish the crucible had spouts. Tongs appear to be hand forged and worked perfectly for handling the crucible, however pouring was a bit tricky since these are straight tongues and not the angled type. The crucible is a bit of a tight squeeze in the furnace, so just be aware that it is at capacity. I was one of those shop geeks in middle and high school wood and metal - enough that when I got to college I had a part time job in a model shop. I've done aluminum and bronze metal casting in several class environments so had been itching to make my own - this was a lot faster and easier than a DIY furnace. Assembly was straightforward - you connect one end of the hose to the burner and the other side to the tank connector. The hose is a nylon reinforced silicone hose - a smart upgrade would be for a stainless jacket - you would NOT want to burn a hole in your hose by accident. I'm also thinking of putting a proper regulator on it. I recommend connecting the tank last since you need to rotate the burner tube in order to connect it into the furnace. You definitely need to use the 3 set screws for the burner - just make sure the inside angled outlet is aligned properly. Put some anti-seize on the threads if you want to disassemble later. Lighting the furnace was pretty simple - put a piece of burning paper inside the (empty) chamber and turn on the gas. The trick is to turn the gas on VERY slowly. It took be at least 4-5 tries the first time because I kept opening the valve too far. You really want a very low flow to sustain the flame. This does NOT have a regulator so you will want to keep an eye on the furnace under operation - I had a pretty full tank and a warm day so I didn't have to touch the valve once I got it up and running. After lighting it, I let it burn for about 4 minutes to preheat, then I put a crucible in with just over a lb (18 oz) of copper scrap, I wanted to test it on copper since copper, brass and bronze all melt around the same temp with aluminum being much lower. Then I waited. It took another 21 minutes (25 minutes from lighting the furnace) to where the copper started to melt. At 35 minutes total I turned off the furnace and poured the ingot. The burn used about a pound and a half of propane (1 b 6 oz) . It should work faster next time - I noticed that the furnace was dripping moisture and steam as this was the first burn for the furnace, and there was likely residual moisture being driven off from the refractory cement. Best of all, remove the burner tube and the whole thing fits in a 5-gallon bucket (with cutouts for the handles).

There are a few minor things with advertising. It DOES come with heat gloves, and they are fair quality. There was a different gas pipe that doesn't measure PSI. Then there were small imperfections with the lid that doesn't allow it to close evenly, though it doesn't affect performance too much. It's not a great idea to try and melt copper as it's very timely and somewhat difficult. However, for things with lower melting temperatures, this forge works phenomenally, especially for such a low frice. Couldn't really ask for a better forge to start out with.

Upon unboxing the first thing I did was inspect the burner remove the burrs from the burner tube and add sealant to the threads and retighten, next I had to cut the tip of the burner down about an inch, or else the fitting would get in the way of the crucible, next I installed the fuel line to one of MY regulators, the included hook up gave me safety concerns so I opted to not even use it. I thought at first "yep, cheap Chinese junk as expected, but the ingot mold and crucible look good, I'll try it." I fired it with the crucible inside at about 2PSI, impressively at such a low pressure it didn't burn into the burner which often happens and closed the lid. I kept it at this level for about an hour to bring it up to temp. I then took off my glove and touched the side of the unit and it was seriously hot, good quality ceramic insulation generally shouldn't allow that to happen but it appeared to be high density, so that's to be expected, dense insulation is great in a forge where you need wear resistance but silly in a foundry. Finally I added a charge of 210 alloy brass and increased to 9PSI. Unit remained quiet and had a minimum of dragons breath which was nice to see! About 25 minutes later my crucible was filled with liquid brass and poured easily. My suggestions for the company or user: 1. Have angled tongs or special pouring tongs, working above molten metal is dangerous, and pouring toward yourself is a big NO! 2. Seal and deburr things better! 3. Use a real regulator, never run blind. 4. Shorten or bypass angled burner tube end. Overall a great little unit though, all issues are easily corrected by consumer or company, especially for the price! Brass is a serious material but didn't have any issues.

This furnace will not last you any longer than a week's worth of smelting and should not be used for smelting anything but aluminum. The furnace is a cheap throw away because you cannot regulate the temperature, the material is cheap, and the durability of the furnace is only good for an hour or two a day of smelting before it becomes hazardous and unusable at the end of the week. Summary: This product will not produce an income close to the price of the furnace before its unusable. The furnace is advertised for beginner smelters and low temperature metals; however, a beginner will not learn anything or produce enough to gain anything in a week before having to buy another or repair. Instead, save your money and buy an industrial grade furnace because it will last long enough to make worthy, income or hobby, without draining your wallet.

This is a decent starter gas furnace if you have a little patience and take the time to prepare. The unit does melt different types of metal without issue. I ordered this furnace specifically because it has an adjustable air inlet on the burner and a pressure gauge after the regulator, which makes it easier to dial in the flame. There are a couple of downsides worth mentioning. The thumb screw that holds the burner in place came out almost immediately. That was not a major issue for me since it was easy enough to rethread. The bigger concern is the ceramic fiber blanket, which feels fairly thin and lower quality than I expected. If you are a beginner like me, this is still a good option at a reasonable price. I would much rather make my beginner mistakes on an inexpensive furnace. Assembly is fairly easy as long as you pay close attention to the direction the fuel jet is facing.

I don't leave reviews often, but I love this furnace and wanted to share my experience. After wasting a lot of money trying to do a DYI furnace I decided to buy this unit. I works amazingly well. I have melted aluminum and copper thus far. The aluminum melted an entire crucible in a matter of minutes. The copper took a bit longer. The crucible is easy to handle and the tongs are great for puling slag as well as handling the crucible. The entire thing took me 5 minutes to set up once I unboxed it.

Fairly well put together, however the gas line is too short and the gas connecter is shoddily made. Do yourself a favor if you buy this particular foundry invest in another has line. There is also no air flow adjustment screw so you must cover it until the the gas is lit. (I place a small piece of duct tape then remove it when the it starts.) Although well made I would invest in a smaller crucible, this one is just a little too big. The tongs are well made and great for lifting but buy a set specifically made to pour, you'll have much better results. All in all for the backyard enthusiast this is a good set-up. If you're just getting started and don't want to invest to much money I would buy this. Then when it wears out, as everything does, by a better quality set.
