<<Disclaimer: Verify this information before applying it to your situation.>> One other thing to note is that Calphalon is aluminum and is not what I would use to cook my food in. The non-stick coating can come off and I have heard it causes the "Teflon flu". I only cook in stainless steel, glass and cast iron. My husband still used a Teflon skillet when he cooks his eggs but the thought of eating bits of Teflon don't thrill me. Never preheat a Teflon pan.
