What to place underneath a convection microwave oven? I bought a Sharp convection microwave oven months ago but to date, I have only used its microwave functions. The reason is because I am worried about the heat generated by the oven in the convection mode and what it might do to the wood-based countertop. What can I place on the countertop to protect it from the heat of the oven?
I'd get a small granite or marble "cutting" board just the size of the oven.

It will help diffuse the heat.
