• Chinese Ding Porcelain - Ding ware is a type of Chinese porcelain that was produced in the northern city of Ding in the Hebei province during the Song Dynasty (960-1279). It is considered to be one of the "Five Great Kilns" of Chinese ceramics, along with Jian, Jun, Guan, and Ru wares.
  
  Ding ware is known for its fine white porcelain body, which was made from kaolin clay, and its elegant shapes and designs. The glaze on Ding ware is usually transparent and has a bluish-white or grayish-white color. It was often decorated with underglaze blue or iron-brown designs.
  
  Ding ware was highly prized during the Song Dynasty, and it was exported throughout Asia and as far as the Middle East and the Mediterranean. It was also an inspiration for other porcelain-making centers in China and Japan. The production of Ding ware declined after the Song Dynasty, and it is now considered to be a rare and valuable collectible.
• Ivory - Ivory is a hard white material that comes from the tusks of elephants, mammoth, walrus and boar, or from the teeth of hippopotamus and whales. The ivory from the African elephant is the most prized source of ivory. Although the mammoth is extinct, tusks are still being unearthed in Russia and offered for sale.
  
  Ivory has been used since the earliest times as a material for sculpture of small items, both in Europe and the east, principally China and Japan.
  
  In Asia ivory has been carved for netsuke, seals, okimono, card cases, fan supports, animals and other figures and even as carved tusks.
  
  In the last 200 years in Europe ivory has been used to carve figures, for elaborate tankards, snuff boxes, cane handles, embroidery and sewing accessories, in jewellery and as inlay on furniture. Its more practical uses include being used for billiard balls, buttons, and a veneers on the top of piano keys.
  
  The use and trade of elephant ivory have become controversial because they have contributed to Due to the decline in elephant populations because of the trade in ivory, the Asian elephant was placed on Appendix One of the Convention on International Trade in Endangered Species (CITES), in 1975, and in January 1990, the African elephant was similarly listed. Under Appendix One, international trade in Asian or African elephant ivory between member countries is forbidden. Unlike trade in elephant tusks, trade in mammoth tusks is legal.

• 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.
