Thang-ga（唐卡）is a special kind of painting. It was found only in Tibet, China. It started from the Tang dynasty（唐朝）. Thang-ga paintings show Tibetan people’s lives. In recent years, Thang-ga paintings have caught the public’s attention. At the same time, the Chinese government has also tried hard to protect the art.

The color of Thang-ga paintings look wonderful and special. Because of the special environment of Tibet and the excellent skills of artists, the paints（颜料）used in Thang-ga are different from other paints. They were made from minerals like gold and silver, as well as some plants. The paints were made by hand and the beautiful colors could last for hundreds of years.

However, with the development of technology, people now use cheaper and more easily-made chemicals to make Thang-g paints. The traditional paints used in Thang-ga paintings took a lot of work and they were made in many secret ways. Later people stopped making the paints and forgo about them. So the skills needed to make them were almost lost. The traditional Thang-ga paintings are difficult to find now.
