All-Clad's MC2 Collection with its industrial styling, brushed aluminum exterior, polished stainless steel interiors and handles is perfect for contemporary kitchens or restaurant use. All-Clad's 3-ply bonded construction ensures exemplary cooking performance. 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 optimum heat conductivity. The long, stay-cool handles, non-corrosive rivets, and sure-fitting lids are all of gleaming stainless. To maintain its appearance, it is best not to put MC2 in the dishwasher.
