The solar furnace is constructed of evacuated glass block solar elements that include an interior face, or surface, of zinc. Because of this material, substantial solar radiant energy is retained and radiated to the interior of the furnace, permitting the furnace to reach temperatures of 300 DEG C. and more when located at latitudes between the 35th parallels. Evacuated insulating elements contain the furnace's heat, each element being an evacuated block with one or more preferably reflective interior panels.
