Abstract: A solar oven. A rectangular cooking pan has a bottom and four side walls and is open at the upper end. It is in an exterior casing having a bottom and four side walls, and having an outer coating to lower the heat absorption. A body of insulation lies between the cooking pan and the exterior casing; the top edges of the body of insulation, the casing, and the cooking pan are coplanar to provide a rectangular shelf. A glass-supporting frame encloses and protects a sheet of low-iron, heat-conductive glass. A mirror-supporting frame has a solid top portion and sheet and supports a mirror combination, which comprises either a sheet of silvered glass or a sheet of polished aluminum, and a polyvinyl backing, so that the mirror combination has approximately 100% reflection on its lower side, below and opposite the top solid sheet. A support arm is pivoted to one side of the glass frame and has a series of openings therethrough.
