ABSTRACT:
The bottom surface of a cooking vessel (1) is provided with a plurality of concentric grooves (3) by form rolling. The grooves are then provided with a coating (5) to absorb radiation heat from a hotplate. Thus in use the grooves absorb radiation heat while the annular surfaces (4), between the grooves which are in contact with the hot plate absorb contact heat. The resulting vessel also has a very strong construction since the annular surfaces between the grooves act as reinforcing ribs.
