It all started in the early 1800s. Though found abundantly on the earth’s crust, it has never been found in its purest state. Rather, it is found as a compound in rocks and other formations on earth. Referred to as Alum, its existence has been acknowledged since the middle ages but in the form of sulphate salts. It was used as medicine, dying and even as a fire resistant. However, in 1808, Sir Humphrey Davey tried to separate it from the sulphate to get at its purest form. In a publication in 1808, he mentioned it as Aluminum, a new element he wanted to isolate. However, in 1809, he mentioned it as Aluminum. Later, British scientists started referring it as Aluminium, as a homage to the line of elements (Potassium, sodium, strontium, calcium, magnesium, and barium) he had already discovered and isolated in their purest form.
