I have never been satisfied with Mizzou as a refractory for actual glass contact and a floor inevitably has glass contact. It just turns to mush and when it does, heat is really scooting right through it to the steel plate and you never appreciate how much heat is being lost down there since you can't see it. Eight inches in the floor sounds good to me.
