Abstract
A microwave pizza maker including a metallic pan, a metallic cover, and a microwave transparent base for removably supporting the pan and cover in spaced overlap alignment forming a partial microwave choke between the side of the pan and a peripheral region of the cover. A layer containing ferrite particles is attached to the undersurface of the pan to absorb microwave energy and produce heat for conduction to the interior defined by the pan and the cover. The base has legs so that the pan is elevated at least an inch above the floor of the oven. The support surface for the pan consists of a plurality of protrusions or spacers to provide a small surface contact area to minimize heat transfer from the pan to the base. The spacers may be fabricated from a different material than the remainder of the base and connected thereto.
