The Dangers of Teflon
Do you know about the history and dangers of Teflon? If you have Teflon pans that predate 2014, throw them away, and definitely don't buy them used. You will have no way to assure their production date. Even though the PFOA's in Teflon have been removed since 2013, Teflon can still release toxic fumes at temps above 500 degrees, why take the chance?
Not only is our cookware non-stick and waterless, when used as designed, it conserves a lot of energy and space. Pictured below you see the stack, with a less than 2 degree difference between the Grand Electra Skillet at the bottom and saucepan at the top.
