filoofny Posted March 16, 2023 Share Posted March 16, 2023 I have a Nargesa H2 two burner gas forge and the compacted vermiculite insulation is crumbling apart. Not so bad on the sides exposed to heat but the backside and other non heat exposed pieces just keep shedding crumbs and disintegrating. I'm thinking humidity breaks this stuff down but the manufacturer of this forge says I'm the only one with this problem which I find hard to believe. https://photos.app.goo.gl/fjR6EwGEhNaoqi4X8 Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted March 17, 2023 Share Posted March 17, 2023 Welcome from the Ozark mountains. Hate to say it, but I have never heard of that forge maker or that type of insulation in a gas forge. It might help to know where in the world you are located.

Zinit Posted January 5 Share Posted January 5 I have an H2 and have been very happy with it. I live in western Norway and have it in my garage, it goes a bit below 0 centigrade (32f) here from time to time in the winter, what’s important with this material when it’s very cold or very humid is to warm it up slowly (open both burners enough to ignite and set them just past red flame, leave it alone for 10 minutes or so to warm up before opening the burners more i keep the pressure from the gas tank at 0.3 bar, no need for more really, 1 bar is ridiculous unless you want to forge weld, melt bronze or make damascus (very bad idea in most gas forges, borax destroys the insulation plates), i use my cheap home made coal forge for anything involving borax, i never put the stuff anywhere near the gas forge.

Frosty Posted January 8 Share Posted January 8 Welcome aboard Zinit, glad to have you. If you put your general location in the header you'll have a much better chance of meeting up with folks living within visiting distance. Mentioning it one time in your introductory post won't stick in anybody's memory once we open another post. Putting an incandescent light bulb in the forge for half an hour or longer will dry it out more effectively than relying on the burners on low. H2O is a byproduct of propane combustion that WILL infiltrate porous materials like those in your forge. A light bulb produces IR radiation without combustion byproducts so the only thing your forge liner can absorb is heat. I don't know much about the H2 forge or their other products, they don't say much about them other than how much better than other brands they are. I'd like a look at the burners, the site doesn't say anything about requiring an electrical connection so I assume they're naturally aspirated. Anyway, try putting an incandescent light bulb in your forge to prewarm and dry it. 40 watt should be more than enough. Frosty The Lucky.
