Lead Ingot

Lead was probably one of the first metals to be produced by man, being known since 3500 B.C., in agreement with archaeological discoveries done in Egypt. The oldest lead piece is in the British Museum and dates from 3800 A.D.. The manner in which prehistoric people extracted lead from its minerals is not well-known. However, there are vestiges of very rudimentary furnaces, done of stone, where these people heated up the lead minerals with bonfires (that burned wood and coal) to extract the element
