The use of two of the oldest traditional plumbing materials, lead and copper, can be traced back to the ancient Egyptians. They used lead oxide as a decorative glaze on pottery, but more importantly, the earliest example of part of a plumbing system using copper pipe, found in the Nile Delta in Egypt, dates from around 2750 BC. The ancient Greeks are known to have mined lead, as did the Romans. The Romans mined and smelted lead on a commercial scale, initially using it for weight and coins before seeing its potential for use in sanitary installations. Both the Greeks and the Romans developed quite sophisticated plumbing systems for their day.
