摘要： A method of making a sanitary basin. The method has the steps of providing a steel basin body, coating a face of the body with a layer of enamel, and burning macroscopic structures into the enamel coating with a laser beam. The structures are interconnected, for example forming a channel network.

摘要： A method for making an enameled sanitary product has a first step of applying a coating compound formed from at least one ground-enamel frit to a metallic base body. The compound contains a thermally unstable additive that decomposes when heated. Then the base body coated with the compound is fired such that the additive thermally decomposes and produces gas inclusions and craters that produce bubbles in and craters on the fired coating compound that are fixed by cooling.
