3-PLY CONSTRUCTION

Different types of metal can be laminated or bonded together. The lamination of metals is done in the raw material stage, in sheets, and blanks are cut from the sheets to be formed into cookware shapes in a press. The entire process is very costly, and this construction is found only on higher priced cookware.

An example of 3 layer construction consists of two outer layers of stainless steel, with an inner layer of aluminum. Many top of the line pressure cookers, and other high quality cookware offer this feature. Another combination, and certainly more decorative is constructed of a copper exterior, aluminum inner layer, and a stainless steel interior.

Look for this type of 3-ply, sandwiched base on quality pressure cookers to avoid scorched food.

This heat distributing base works by absorbing and spreading the heat evenly over the entire base of the pan. Unlike plain SS, the 3-ply base will help you avoid hot spots that burn food. Pots with 3-ply bases also require less fuel to maintain the heat.
