SteveC69 Posted December 26, 2021 Share Posted December 26, 2021 I'm starting on my first forge, and wondering if I can use a castable refractory by it's self, or do I need to use some kind of kaowool first? Quote Link to comment Share on other sites More sharing options...
Frosty Posted December 26, 2021 Share Posted December 26, 2021 Welcome aboard Steve, glad to have you. What kind of forge? Solid fuel: coal, charcoal, wood, etc? or Propane? They're two entirely different machines. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted December 26, 2021 Share Posted December 26, 2021 Use it for what? Lining, exterior, forgepot? You have an idea of what you want to do; we don't and have a LOT of ideas on what can be done. Details will help sync things up! Remember "can" doesn't equate to "good". If I was building a forge for lots of heavy work bringing in lots of money I could use for fuel; I would line my forge very differently than if I'm doing small projects all out of my own pocket.

SteveC69 Posted December 27, 2021 Author Share Posted December 27, 2021 I'm planning on making a propane forge, probably out of a propane cylinder or something similar. And just doing small stuff. It would be nice if I could just pour something and achieve a nice thick wall and not have to mess with wool. Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted December 27, 2021 Share Posted December 27, 2021 You can do that however you will be making a huge heat sink and loose a lot of heat through it. If you don't care how long the forge takes to heat up and how much propane it consumes by all means go ahead with that plan. It is very simple to install several inches of ridgized K-o-wool or Inswool then coat it with Kast-O-Lite 30 and Plistix 900F for a very hot and efficient forge.

ThomasPowers Posted December 27, 2021 Share Posted December 27, 2021 The time you lose waiting for that type of forge to heat up will quickly exceed the time it takes to make one that is more insulative and saves time and money! Quote Link to comment Share on other sites More sharing options...
SteveC69 Posted December 29, 2021 Author Share Posted December 29, 2021 Ok, so it looks like you guys are recommending 2 or 3 inches of K-O-wool and then coat it with Kast-O-Lite 30. I guess I'll give that a try and see how it turns out. Thanks for the help. Quote Link to comment Share on other sites More sharing options...
