Thermocouples Maver,
Though mine is a bread oven, I've found using thermocouples invaluable for measuring mass heat. I can get to hearth brick readings of the 700 F range fairly quickly, but the mass heat simply is not high enough to bake repeatedly unless my slab and cladding are at the 450 range for each. I have a thermocouple in the hearth bricks, one inch below the cooking surface; one in the slab; one in the dome, about one inch above the brick surface, and one in the middle of the cladding. These readings, to me, mean a lot more that the surface readings given by an IR gun.
Food for thought.
