Bauer Pan Discolouring.

My old black BAUER pan, I had for many years and the glass lid broke. I was advised to ge tthe new spotted pan, as there are no big lids available anymore. Like an IDIOT, I swapped my old pan for this new spotted piece of junk. As we live on a farm, we ONLY use gas. Two weeks and the pan was staining. I complained to the lady in the shop at Stone Cradle and was told, she cannot take it back, because of the discoloration. I strongly advise people to save their money and NOT buy Bauer Pans as the new stuff is *******.
