Abstract
A culinary vessel is made from two sheets of different metals or alloys laminated together and stamped to form a vessel having a bottom and a side wall. The bottom incorporates small stamped cavities such that the cavities formed in the outer sheet enter complementary cavities formed in the inner sheet. This strengthens the bond between the two sheets.
