The ones that I have used are black too, I'm not sure it is painted, and they were fine in the oven. It may be that over time it might affect it, but doesn't seem to be a problem now. They are so much easier to work with!
That was a really good deal on the pans! I've gotten a couple like that on eBay, where with shipping and all, the pans were a little over $2 each. When I get my knees repaired and can get around, I think I'll be making the garage sales too! I made it to a Goodwill and a resale shop today, but no pans to be had. I'll be on the lookout for cake plates from now on too.
My decorating teacher (not a Wilton class) doesn't like the Wilton pans, but I think they are fun, and using the baking strips attached with the butterfly clips, they are fine. I just got a Barbie pan in the mail today, looks like new and even has the two lay-ons with it, seems like she will always be popular. I think I can make an angel with this particular pan as well. I just made a list of my pans and since October I have collected 35 various pans, and three tier sets, round, square and one called flat diamond, so I figure I've got a good start! I am definitely addicted!
