Well, this is getting interesting! I stuck the BGE firebox in my oven and and gradually heated it up to 500*+ and the JB-Weld joints that I had covered with furnace cement bubbled up, but as of this time are still holding up. It cured for over 5 hours at 500* and was still hot to the touch 2 hours later. I plan to do a test burn with lump today.
What I did was notch out a V on both sides of the cracks with a Dremel and packed it with JB then a couple thin coats of furnace cement and just built upon that and am doing the same on my Medium Hibachi Pot and set a heat lamp over it. Time will tell?
