Abstract
A cooking item including a vitreous coating with improved impact-resistance properties, and a method for manufacturing such an item. The method for manufacturing includes optionally treating a concave internal side of a substrate having the end shape of the cooking item, the concave internal side being arranged on the side of the food to be introduced in said item, and a convex exterior side to be arranged on the heat source side, so as to obtain a treated internal side adapted to cause a hard base layer to adhere to the substrate, The method further includes preparing an adhering hard base layer on said internal side of the substrate, be it treated beforehand or not, and preparing a non-stick coating on the hard base layer.
