- Ming Dynasty - The Ming Dynasty was a ruling dynasty of China from 1368 to 1644. It succeeded the Yuan Dynasty and preceded the Qing Dynasty. The Ming Dynasty was established by Zhu Yuanzhang, a former Buddhist monk who became a rebel leader and eventually overthrew the Mongol Yuan Dynasty. During the Ming Dynasty, China experienced a period of relative stability and prosperity. The government was centralized and bureaucratic, with the emperor at the top of the hierarchy. The Ming Dynasty is known for its cultural achievements, including the development of porcelain, the invention of movable type printing, and the construction of the Great Wall of China.
- 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.
