[Clay]
 
   Clays are perhaps the oldest materials from which humans have manufactured various artifacts. The making of fired bricks possibly started some 5,000 years ago and was most likely humankind's second earliest industry after agriculture. The use of clays (probably smectite) as soaps and absorbents was reported in Natural History by the Roman author Pliny the Elder.
