6 KG Propane Melting Furnace Kit w Graphite Crucible and Tongs 1300°C /2372°F Casting Refining Smelting for Precious Metals Gold Silver Tin Aluminum 7-in-1 Melting Casting Tool

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.

I followed the instructions and it shot flames everywhere. I then tried to take it apart to double check and the parts just snapped.

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 love this horno I put in all mine soda pops and I made all in ingots everything works good

Unit arrived damaged but reading other reviews it doesn’t impact performance or safety but still disappointing. The crucible is packaged inside the unit which caused the damage during shipping. Also has issues with the gas nozzle being out of position so it would t fire up properly. Once adjusted it worked great. Other than the two issues above this is worked great, large crucible included with kit (can’t go larger) the mold it included is a little small compared to the crucible though so definitely pick up another one or two molds.

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.

Oft auf einem Videoportal gesehen. Vorallem Leute die es mit 3D druck kombinieren. Erst die Form gedruckt eingegossen. Dann ausgebrannt. Und nachgegossen. Dafür habe ich mir dieses Set geholt. Die Verarbeitung ist gut. Ich hatte keine Risse im inneren. Auch der Tiegel und die Form machen einen guten Eindruck. Zange und Zubehör ist in Ordnung. Ein Freund hat mir allerdings empfohlen einen Druckminderer und Explosionschutz beim Einsatz von Propan zu nutzen. Das kann ich jedem auch nur ans Herz legen. Kostet zwar nochmal ein Paar Euro aber die Sicherheit ist es mir wert. So kann man auch gut die Power regulieren. Alles in allem bin ich echt zufrieden.

Works good. Exactly how advertised. My only concern is my crucible is cracked after the 3rd melt. Did the warm up procedure properly to. How do go about getting a replacement?

Llego bien solo que la lana cerámica no llego como lo dice en las especificaciones falto lana en el recubrimiento faltando 4 cm al nivel diámetro, deben de enviar los artículos como lo especifican. Ya ir viene muy delgada la lana cerámica.

Other then having to get some parts to upgrade the setup between the burner and tank, the furnace is solid and works fantastic. Tongs and mold are good too. Crucible cracked though after following all instructions. Seller sent replacement and was very curtious but replacement quality was kinda poor. Again following all instructions included with the crucible its almost cracked beyond use. Crucibles from other sellers not having any issues and not having cracks like this so pretty sure its just the crucible.
