Well we got our oven up to the 500 degree temp tonight. We put in 42 cuft of vermiculite which gives us 6'' or better all around the dome inside the inclosure. Before we did that we put a drop light inside prior to the fire and checked for cracks. Found none. We did see some cracks on the outside of the dome in the Heatstop coat. We put 2 coats on. One last one after the dome was complete. In all honesty several days after the final top coat was added and way before any matches were lit we did have some cracks from drying out and shrinking. While the fire was going tonight we checked to see if we saw any steam or smoke coming from the cracks and there none. the cracks were actually the furthest away from the flames. When reading the temp the hottest it got on those side walls so far was about 300degrees. The hottest the dome on the outside got at 500 degrees inside was only 108.
Is it safe to assume that the cracking on the outside is pretty typical and we should not worry. Remember that there is no cracking on the inside in the bricks or the mortar joints that we could see..
Any thoughts are appreciated.
