## Questions & Answers

**Q: When I receive the product, the internal yellow fireproof mud is damaged. Will it have any effect?**
A: The damage of fireproof mud will not affect the use of the product.Furnace interior is fully lined with 2"" of ceramic wool, it can withstand high temperatures of 1400 ° C

If you are worried, you can use the outer soil or red mud to directly smear the inner wall, which will have a better insulation effect.

If you are a perfectionist, it is not recommended to buy this. I have used a lot of gas melting furnaces. The fireproof mud on the inner wall will not have any effect. And this product is really easy to use, LOVE IT!

**Q: How long did it take to heat the unit and crucible to your desired temperature?**
A: These furnaces take approximately 5-6 min to reach the desire temperature 500℃
Thank you !

**Q: I have bought other products. I am using an aluminum screw hose shaper and it is stuck and difficult to peel off.How to solve this problem?**
A: Other products use three screws to fix the burner. The screws are easily deformed during heating, which makes it difficult to take them out. In response to the problems of products in this market, our FASTTOBUY have introduced this new and improved product. The burner used has internal threads (internal screws) that are directly tightened on the stove and have better sealing.

**Q: What is the volume of the crucible?**
A: Furnace outer diameter：φ28CM
Furnace height：27CM
Furnace inner diameter：φ16
Furnace height：17CM
Crucible size：φ120*152
Crucible capacity：650ML
It Can be melted 6KG copper 1.6KG aluminum, 7KG silver, 12KG gold. It takes 15-25 minutes to melt 5.5KG copper

### ⭐⭐⭐⭐⭐ Great starter furnace for metal casting - operation takes some finesse - tips for operation...
*by Y***U on August 24, 2020*

The media could not be loaded. 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 chamberThe 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).

### ⭐⭐⭐⭐ Not too bad (For a beginner)
*by C***R on February 27, 2020*

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.

### ⭐⭐⭐⭐⭐ Great after some modifications!
*by A***R on August 31, 2020*

The media could not be loaded. 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.
