I followed the instructions about using vegetable on it an placing it in the over for 20 minutes. I let it cool and cleaned it with a paper towel.
The first time I used my copper pan it warped. Now it rocks back and forth when I fry any thing such as sausage and eggs. I did not put it on high heat so I know I used it right. I'm very disapointed in my pan.
People think twice before you buy any of these pans.
I would send it back but it'just too much trouble. However I will tell all my friends not to buy one.
