Pat Masterson Posted December 14, 2020 Share Posted December 14, 2020 Good morning - I was curious if anyone had a brand of fire brick to recommend for the bottom of my propane forge. I’ve had it about 8 months and it held up pretty well but then it in about the last month it’s become pretty bad. I can’t tell if it’s the brick itself that melted or if it’s from the work itself but it basically looks like a puddle of steel that hardens when the forge cools. When it’s hot I can feel the work sticking to it and some of it will actually come off and stick to the work. I will add pictures. But like I said it lasted pretty long then this seemed to come out of nowhere so I flipped the brick but now just after two sessions on the fresh side I can see the same thing starting to form. It’s the brick that came with this devil forge I bought. So is a better fire brick needed or is this going to happen regardless? Thanks.

Irondragon Forge ClayWorks Posted December 14, 2020 Share Posted December 14, 2020 Fire bricks in a gas forge are considered consumables. If you are doing any forge welding it will accelerate the brick's deterioration. I would pick up some Kast-O-Lite30 and cast my own bricks.

Pat Masterson Posted December 16, 2020 Author Share Posted December 16, 2020 No flux but it has been up to forge welding heat quite a few times Quote Link to comment Share on other sites More sharing options...
