Aluminium Foil
Aluminum Foil is a very common and popularly used material. The idea behind foil is to take a solid metal and process it until it’s very, very thin. Aluminum foil is made from materials that naturally occur in the earth. Making these materials into the roll of foil found in most homes is a process done in factories by very large machines that melt the materials at high temperatures, mold them into large, heavy, solid blocks of aluminum (ingots), and then use pressure roll the huge slabs over and over until they thin out!
