The All-Clad d3 stainless cookware line features a tri-ply construction that heats evenly and is dishwasher safe. The cooking surface is hand-polished 18/10 stainless steel that will not react with food. The inner core is pure aluminum, not just at the bottom, but all the way up the sides. All three layers are bonded together for optimal heat conductivity -- perfect for browning and searing. The stainless exterior is magnetic so it is induction compatible.
