Bests & Worsts Reviews from Amazon

I just purchased this set because I read that the hard idionized pans were unhealthy. I replaced an entire set of calaphalon (sp) for this Green Pan set. I hand owned my Calphalon set for approximately 7 years and had no issues with them other than reading they were unhealthy. This Green Pan set arrived well packaged and are absolutely beautiful and appear as described; however, I used the large casserole pan for the first time last night to make spaghetti sauce and I am not pleased with the outcome. It's the first and only piece I have used thus far out of the set. I followed all of the manufacturer's instructions, using a low temperature setting and nylon utensils. The piece held up wonderfully during the cooking process and the sauce came out wonderfully, never sticking during the slow simmering process. So, at this point I was a happy camper. After dinner and allowing the pan to become completely cold, I hand washed it in warm water with a soft soapy dish cloth. No matter how long I washed the pot, I could not get the orange stain from the spaghetti sauce off the interior bolt heads. They are permanently orange. In addition, the ceramic coating on the bolt heads are beginning to flake off - after just 1 use and washing. I attempted to comment about this problem directly with Amazon and the manufacturer, but the only option was to return or refund the entire set. I no longer have the box the set came in, and I am not able to repackage the set in the same manner it was received. Plus, why should I return the entire set instead of merely replacing the defective piece? Simply said, this is a much too expensive set to have these types of issues. I'm truly worried I made a mistake purchasing this set. Hopefully Amazon or Green Pan will reach out to me to resolve this issue. If so, I will update this review.
