I have some shiny aluminum baking pans, and others of aluminum with a black coating (no , it's not non-stick stuff). Does is make a diff on time or temp? I have both types for muffins, and 8 incher etc.

Btw, I HATE my non-stick muffin tins, but I keep 'em in case someday I need to whip up a couple of dozen for some event ( altho I can't imagine WHAT.). I guess it's stupid to keep em, tho, and even more stupid to have bought' em.
