• Tortoiseshell - Tortoiseshell is a translucent material that comes from the horny carapace of a certain types of turtles, including the hawksbill turtle. It is often therefore mounted on a colour underground - often red - or inlaid with gold or silver thread, as seen in Boulle furniture.
  
  The texture and colour nuances of the material are extremely important. Heated tortoiseshell can easily be formed into various shapes. Like other natural materials, tortoiseshell becomes more beautiful with use. In a time before plastic, tortoiseshell was widely used for small objects such as combs and powder compacts.
  
  In 1973, the trade of tortoiseshell worldwide was banned under CITES (The Convention on International Trade in Endangered Species). Prior to importing or exporting items containing tortoiseshell a CITES permit must be obtained. Tortoiseshell items cannot be traded on Ebay.
  
  "Faux tortoiseshell", another case of man initiating nature, is made from old-style plastics such as celluloid and cellulos and is coloured with red, yellow and brown spots to imitate the genuine article. It is commonly used in glasses frames, musical instruments and costume jewellery.
• Song Dynasty - The Song Dynasty was a ruling dynasty in China from 960 to 1279 AD. It was divided into two periods, the Northern Song (960?1127) and the Southern Song (1127?1279). The emperor was the ultimate authority, but he relied on officials who were selected based on their merit and skills rather than their family background or social status. The Song Dynasty was a period of great artistic and cultural achievements, particularly in the areas of poetry, painting, and calligraphy. The Chinese invented the printing press during this period, which revolutionized the spread of knowledge and ideas. During the Song Dynasty, China had a prosperous economy and was a centre of international trade, particularly in luxury goods such as silk, tea, and porcelain. The use of paper money became more widespread during this period, facilitating commerce and trade.
