I just moved down to Arizona and won't be able to get my real cookware (old Calphalon Pro, no coating) out of storage until the spring. While visiting junk stores, I picked up an old Circulon pot and pan for about $5. They were dirty and when I cleaned them, I noticed that the nonstick coating is missing in small areas in both. Are these still safe to use? Is there a way to add more coating to them? No huge loss if they're not safe to cook in. I can still use them for hobby stuff or fill them up with dry cat food. Also, any suggestions for cheap but decent pots and pans for the next six months or so?
