Features an extra-thick copper exterior.  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.  Stay-cool handles and non-corrosive rivets of gleaming stainless.   It is best not to put Cop-R-Chef in the dishwasher.
