Why Does Household Aluminum Foil Have One Bright Side And Other Dull Side

- Jul 24, 2019-

The difference in appearance between dull and bright is due to the foil manufacturing process. In the final rolling step, two layers of foil are passed through the rolling mill at the same time. The side coming in contact with the mill's highly polished steel rollers becomes bright. The bright side can reflect the heat on to the food to be cooked, using a long-established scientific principle that bright surfaces reflect heat and light.
