ABSTRACT:
A first coating of enamel slip of a conventional type for aluminum is applied on the bottom face of a culinary vessel of aluminum or aluminum alloy, then heated in order to produce partial evaporation of water from the coating. Without allowing coating to cool, a second coating of abrasion-resistant enamel is applied on the first coating and reheated in order to produce complete evaporation of the volatile components. The two coatings are then immediately fired in order to sinter the enamels.
