Lagostina's Artiste-Clad Copper cookware set has been designed for the at-home chef who demands the very best. The hammered copper tri-ply clad technology ensures uniform heating with precise temperature control. The high quality 18/10 stainless steel interior is durable, non-reactive and easy to clean. The riveted cast stainless steel handles are designed for commercial use and ease of handling. The stainless steel lids entrap and recirculate steam, thereby locking in flavour and nutrients. The beautiful copper exterior with hammered design is the ultimate balance of superior design and technology.
