 In the early 1900s, having worked on a form of nichrome known as chromel, working with Marsh over the alloy he deduced the usage which could be used as a heating element.The heating coil was created using nichrome, and was later used in early versions of the toaster, and the electric kettle.The heating coil was one of the first projects for "Hoskins Manufacturing Co."; Hoskins had considered manufacturing toasters, but later abandoned the plans to focus on the coil itself.
