Abstract
A cooking utensil having an enamel coating of a first enamel layer (7) covered in the zone of the bottom (1) of the utensil with a second enamel layer (3) which is in turn covered with a non-continuous third enamel layer (4) constituting a decoration and applied by screen process after drying of the first layer, these three layers (7, 3, 4) being obtained from an enamel frit and being fired simultaneously. The two enamel layers (3, 4) contain glass beads (5, 6), at least a certain number of which have a diameter of greater value than the thickness of these enamel layers and project from the surface of the layers, a certain number of beads (6) of the non-continuous third layer (4) being applied on beads (5) of the second layer (3). The second layer also contains heat-conducting flakes. The enamel coating offers enhanced resistance to wear and high thermal conductivity.
