Ancient Egyptians were likely the first to extract lead, which they used to make small sculptures. Compounds of lead have also been found in Egyptian pottery glazes. In China, lead was used to forge coins by 2000BC. The Greeks were the first to recognize lead's corrosion-resistant properties and applied lead as a protective covering on ship hulls.
