Abstract
The article is constituted from a plate produced from a relatively soft first metal (1). It has, on one of its faces, a metallic element (2) in the form of a perforated sheet or a grid produced from a second metal or alloy harder than that of the plate (1). The metallic element (2) is fixed to the plate by drop-forging or stamping in order to embed it, at least partially, in this plate. The article is especially useful as a cooking vessel.
