Abstract
The invention is a unitary solid interface adapter for placement at the bottom of a wok. The adapter is made from a thermally conductive material and has an exterior shape substantially in the nature of a frustum of a cone. The upper surface of the adapter is concave in the shape of a sector of a sphere such that a traditional wok will nest therein with approximately equal contact over the entire interface therebetween. The bottom surface of the adapter is substantially flat for maintaining a solid stable perch on either electrical stove elements or gas range lattice support structures. The bottom of the adapter may be provided with anti-slip protrusions which prevent the adapter from sliding on the top of the range element. The side of the adapter is angled outward in a conical fashion such that the heat generated by a smaller area of element at the bottom surface of the adapter may be delivered to a greater area of the wok surface for maximum usable cooking area. The adapter can be provided with a handle attachment detent such that a detachable handle may be attached thereto for transporting the adapter while it is still hot.
