Insulating a gas forge

- There are many ways to insulate a forge, this is just the way I chose to do it. It is very energy efficient and reaches forge welding temperatures easily. I hope this helps you complete your build!
This is why I'm looking at forge vid's instead of building 1 because my math skills are garbage! I would have ruined so many bricks! On the other hand this was a very informative build, great job!!!
I feel like the video just ended abruptly lol. great stuff. I plan on doing the same this spring to make my foundry. I have also thought of doing a casted one but think I will do the wool instead
It did I apologize for that but I promise you did not miss any information. The wool is amazing, I use it for lining gas kilns as well and it holds up really well. Make sure when you forge weld that you protect it or the borax will eat through it. I use standard kiln shelf for that. Good luck!
I'm going around looking for alternatives for my gas forge build, I also have an old airtank I am waiting to cannibalize. The wool stuff is what I was planning on, but I've now read reports that it has asbestos like hazards so I don't want to deal with it at all, even if it's not as bad as the real deal, it's still enough that several institutes have issued warnings about handling it.
Just casted its better
Whats the name of the name of the blanket you out around the forge
Would you need to add some sort of solid bottom inside the forge, such as a firebrick, on top of the kaowool for material to rest on when forging, or will you just leave it as is so the material rests on the wool?
I use pieces of kiln shelving. It's nice and hard, it handles the high temperature and the flux I use for forge welding takes a while to ruin it.I
Have you tried lining the outside with kaowool instead? I'm in the process of building a foundry and I was thinking about doing kao wool on the outside then firebrick on the inside then sealing it with refractory cement.
That would work very well as that's how pottery kilns are built. You could coat the brick with itc-100 to help protect it. I chose to do it the way I did because it is easier for me to replace the wool when the time comes. I also use kiln shelving where you lay the hot metal, it's hard and protects your forge.
No other refractory coating? It is my understanding that direct flame contact will break down kaowool in short order?
The best coating to use is itc-100. I used silica ridgidizer because it was only $15 as opposed to $140 for the itc-100.
Talk to Wayne Coe. He sells Matrikote for $20 per pint, which is a high-alumina refractory coating every bit as good as ITC. I have ordered quite a few products from him. He buys in bulk from a local supplier. www.waynecoeartistblacksmith.com/
Man my forge is junk compared to all these im just using a 9 inch steel pipe 3 feet long with a hole cut in the middle for the burner and a brick to hold in the heat from the back end. I dont forge much though
you should put the kaowool on the outside
You could do that. I thought it would be much easier to replace the wool when it got ruined through use. You could also just use two layers of wool or just use the brick alone. I added the wool as an extra layer of insulation to help get me to forge weld temperature faster.
sir, i wanna see a insulating material cyclinder, that contains gas
I wanna see the forge going????
What happened? Where’s the end of the video?? 🙁
Check out my other videos to see the burners built and put together.
Why not just use two layers of the kaowool?
you certainly could, but I have a lot of experience using that stuff on gas kilns and it has a tendency to sag a bit. You can remedy it with a coat of ITC but its expensive. Its the first time I used rigidizer and it works well and at a portion of the cost.
what did you use for a rigidizer as an itc alternative
Silica ridgidizer.
its been almost two years of use in my forge and it is still holding up like a champ. It has been through many forge welding jobs, which is the hardest on forges.
