Rado Dome layers from the outermost part or top of the dome are as follows; it is outdoors so the first layer exposed to the atmosphere is troweled on castable refractory cement. Under that is ceramic fibre-insulation blanket. Then more re-fractory cement under that. Then I have more insulation between that layer of cement and the stainless which is facing the hearth. So in reverse its the fire, stainless, insulation,cement, insulation, and topped off with cement. In other words the whole interior of the dome is lined with stainless.
Now the hearth which is 34" x 34" is as follows; From the inside of the fire-box down; a course of fire-brick with the 2" thickness down. Under that is 1/4" ceramic fibre board,then 1" blanket, then 1" blanket, then 1/2" pcs of board. Supporting that is is i/8" steel plate which is the bottom-most section of the of the whole structure. I am sending you this now and then if you still can not picture it I can send pictures. To me the fault seems to be that the stainless faces the fire and does not absorb the heat.
