ABSTRACT:
A more efficient flat bottom pot or pan is obtained by (a) the introduction of an initial central downward depression in the bottom plate in the order of twice the plate thickness to avoid the undesirable upward bulging of the pot bottom as a result of aging, (b) providing heat transferring fins in a spiral pattern to the bottom and helical pattern to the side wall of the pot or pan for more effective heat transfer from the stove flame to the pot or pan, and to stabilize the pot with its central depression for placement on flat surfaces, and (c) providing a detachable shielding skirt around the pot to reduce the heat loss from radiation and convection.
