Hi I’m build my first oven I’ve made the vermiculite top with a yoga ball I’ve got some bricks that came out of storage heaters for the base I was wondering could I cement the top to the heater bricks then cook directly on them Or I have another option I’ve a large quantity of clay tiles so could I lay these on the top of the fire bricks then cement the top? All help would be great Thankyou

The fire bricks are normally the cooking surface, but you must insulate between the firebricks and the supporting slab. The floor bricks are better laid loose rather than mortared, to allow for differing thermal expansion and possible replacement. A vermicrete dome is a poor choice for an oven as it lacks strength and thermal mass.
