I poured buckets full of thick mud into the void above the bottles, and screeded the whole mess with a big 2x4.

I let the mud dry partially, and then my daughter and I set firebricks in the mud. These firebricks are the hearth-- the actual baking surface. The mud beneath the bricks holds heat from the fire. The bottles beneath the mud keep the heat from leaking out.
