Aluminum foil has a shiny side and a dull side. Some people believe that one side or the other should be used for cetain purposes. Not true. It makes no difference which side is up. The only reason the two sides look different is that in the final stages of rolling out the metal, two sheets are rolled together as a sandwich to save time. Where they contact the polished rollers they come out shiny; where they contact each other they come out somewhat duller.
