Fireclay between Bricks
Posted by Chuck (208.220.161.2)
Was had trouble laying up the vertical wall of the firebox due to my firebrick rocking and not sitting even. What I did was to mix some fireclay and water into a "soupy" mixture and dip the bottoms of each firebrick into it a bit before putting it in place. This seemed to work very well in leveling things out.
Question: Was I susposed to put aluminum foil between the wall firebrick before I poured around to hold them in place? I couldn't find it anywhere in the documentation (only over the dome), but the bricks sucked the moisture out of the concrete quite fast.
