When did tin foil become aluminum foil?
Foil made from a thin leaf of tin was commercially available before its aluminum counterpart. In the late 19th century and early 20th century, tin foil was in common use, and some people continue to refer to the new product by the name of the old one. Tin foil is stiffer than aluminum foil. It tends to give a slight tin taste to food wrapped in it, which, alongside being cheaper and more lightweight, is a major reason it has largely been replaced by aluminum and other materials for wrapping food.
