Lead
Element (Pb), Atomic No. 82, density 11.36 kg/litre, M.Pt 327°C
Lead is a very soft bluish-grey metal, and so early lead coins do not
survive too well. However, it has been used, particularly in southern India
around the time of Christ, in China, and in Burma and Siam during the 19th
century. Because it casts well and has a silvery appearance when new it has
often been used for forgeries, especially when plated to replicate gold
coins.
In Roman times lead was used for tesserae, which were tickets or tokens
(also made in bronze) that were distributed by the emperor (amongst others)
entitling the holder to either food or money.
In its normal state it tarnishes rapidly to a dark grey colour, and has
extremely poor wear resistance.

In ancient Predynastic Egypt (ca 4000-3000 BC) galena or lead sulphide
was used in the manufacture of kohl or eyeliner and indeed a striking
feature of Egyptian art is the beautiful and exaggerated lining of the eyes.
Stone palettes for grinding kohl are found in ancient Egypt along with
artifacts of lead indicating that lead was one of the earliest metals to be
smelted since lead ore is easily reduced and does not require very high
temperatures. Lead was commonly alloyed with copper and bronze for making
castings. In De Re Metallica, a Renaissance period text authored by Agricola
more than five centuries ago, the Westphalian process of smelting lead ore
is described where lead ore is smelted in an open hearth. The mineral-rich
Aravalli region of Rajasthan was one of the important early lead mining
regions in antiquity. The use of low melting lead-tin eutectic as a solder
became common in Europe by the late medieval period.
