10 x 5

Hello again All!

I recently had some trouble with sourdough stripping the non-stick coating off my non-stick pans. I lined most of the surface area with parchment, but the ends were uncoverd. When they came out, they were silver and the pans (ends) were bare. While I would love to know why that happend (I retarded them in the fridge overnight. did they just spend too much time in there?) I would really like tips on baking in 10 x 5 pans.
