did not build the mold very heavy duty, might be able to get a couple off of it. If I was to try to do that I would make the outer mold also and reduce the labor.The thought has crossed my mind though, they sell for about 2400 dollars plus shipping from what I found online.

pulling........... I am actually a fairly good cook. do all the cooking at home and for family functions. family cant wait to be invited for dinner

it is high temp, medium density refractory rated 2500 degrees for interiors of furnaces. this retains heat, you might want a lightweight insulating refractory so the exterior does not get hot ???
there is a company heat stop which has these products available. I used a commercial product I was able to get locally from a company I did some work for. either would work for making a slab.
also the curing process is important to help minimize cracks. you need to start very small fire, paper, bring refractory to 100 degrees let cool, 200 degrees let cool, 300 degrees let cool up to 800 degrees .
