Boyhowdy Posted January 17, 2013 Share Posted January 17, 2013 Here is a question I asked in the Iforge chat, and Just got a bunch of jokers trying to be funny.I have a three burner Propane Forge that uses way too much fuel for my pocketbook. I am building a smaller single burner, and would like to know: "Which is better to line it with, Soft, or Hard Bricks?" I have hard brick in my current forge, and I feel the bricks are absorbing alot of the heat. Any suggestions would be greatly appreciated. Thanks Quote Link to comment Share on other sites More sharing options...
Chinobi Posted January 17, 2013 Share Posted January 17, 2013 i believe the conventional wisdom is to build with soft brick with a liner of hard brick on the bottom for wear and tear and some kind of coating on the interior, i wont embarrass myself further by recommending things i have never used though. skim the rest of the subforum, there are many other threads for exactly this question. check out also zoellerforge.com for more information on various small DIY gasser builds and the requisite materials. good luck!

WayneCoeArtistBlacksmith Posted January 17, 2013 Share Posted January 17, 2013 Soft brick deteriate to quickly and hard brick are a heat sink. Check out the tutorial on my website on the Forge Supplies page for building a gas forge my way. Quote Link to comment Share on other sites More sharing options...

jcornell Posted January 17, 2013 Share Posted January 17, 2013 Larry Zoeller has some pictures of soft bricks mortared together to make a forge body. I've built one of those and I can affirm that it's a nice forge, but soft firebricks are not designed to be structural like hard bricks - they expand and contract and then crack. I rebuilt my soft brick forge a few times and then called it quits and built a metal can lined with superwool. The soft bricks will work well, but they'll work better with a coat of ITC or something similar (Plistix, homebrew kaolin/zircopax, etc.) You might get better results with the soft fire bricks held together in a metal frame - which you'll also find pictured at Zoeller's site. I don't use a hard brick for my floor - I use a slice from a kiln shelf, which is a bit thinner, and thus doesn't suck up as much heat.

According to his website he will be closed for a couple months, due to medical problems. He does have quite a selection of parts.

Sukellos Posted January 24, 2013 Share Posted January 24, 2013 I used soft brick for doors on my forge and they are cracking on me. Quote Link to comment Share on other sites More sharing options...
