Metal wire heating elements first appeared in the 1920s. These elements consist of wire made from Chromel, which is made from nickel and chrome and it is also known as Nichrome. This wire was then coiled into a spiral and wrapped around a ceramic body. When heated to high temperatures, it forms a protective layer of chromium oxide, which protects the wire from burning and corrosion, and causes the element to glow.
