Abstract: The present invention relates to an improved oven configured to heat or cook an item and preferably pizzas. The oven includes at least one heating gas pathway for heating gas moving within the oven and an item supporting surface on which to place the item to be heated. This item supporting surface has a defined degree of thermal communication with the heating gas pathway. The oven also includes a heating chamber located above the item supporting surface, with this heating chamber being in thermal communication with the upper surface of the item to be heated and thermal communication with the heating gas pathway. This heating chamber also includes a transition port for heating gases. When the oven is used the item is heated by thermal communication through the item supporting surface to a first degree and by thermal communication with the heating chamber by a second degree.
