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.

A cooking utensil having a bottom (1) entirely covered by a first enamel layer (7) which supports a second continuous enamel layer which in turn supports a second continuous enamel layer (3) which supports a non-continuous third enamel layer (4) constituting a raised surface 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, wherein the second and third 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 said enamel layers and project from the surface of said layers, a certain number of beads (6) of the non-continuous third layer (4) being applied on beads (5) of the second layer (3) and wherein the second enamel layer (3) contains mica flakes (9) which are covered with a member selected from the group consisting of TiO2, Fe2O3 and a mixture thereof and which are oriented in a direction parallel to each other and to the surface of said layer and partly overlap each other, said third layer being free from said flakes.
