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.

Method for producing a cooking vessel having a bottom and a side wall, comprising the following steps:
- a) applying on a first plate produced from a relatively soft first metal and having a substantially uniplanar outer surface, a first metallic element in a form of a perforated sheet or a grid produced from a second metal or alloy harder than that of said first plate, a surface of said first metallic element defining a bottom portion of said cooking vessel;
- b) fixing said first metallic element on said first plate by drop-forging or stamping in order to embed it, at least partially, in said first plate, whereby portions of said substantially uniplanar outer surface of said first plate form an interface between said first plate and embedded portions of said first metallic element;
- and
- c) deep-drawing the assembly constituted from said first plate and said first metallic element fixed to it in order to produce said cooking vessel.
Method for producing a cooking vessel having a bottom and a side wall, comprising the following steps:
- a) superposing a first metallic element, a first plate produced from a relatively soft first metal and having a substantially uniplanar outer surface, and a second metallic element, said first and second metallic elements being in a form of a perforated sheet or a grid produced from a second metal or alloy harder than that of said first plate and having their surfaces defining a bottom portion of the cooking vessel;
- b) fixing said first and second metallic elements to said first plate by drop-forging or stamping in order to embed them, at least partially, in said first plate, whereby portions of said substantially uniplanar outer surface of said first plate form an interface between said first plate and embedded portions of said first metallic element;
- and
- c) deep-drawing the assembly constituted from said first plate and said first and second metallic elements fixed to it in order to produce said cooking vessel.
