Thangkas are mostly heavy color paintings, and the pigment preparation is very particular. The pigments used to draw thangkas are traditionally gold and silver (the gold part of the picture is made of gold, and the silver part is made of silver), coral, pearl, malachite, cinnabar and other precious mineral materials. Therefore, the maintenance of thangkas is extremely important. So what's the taboo of wearing Thangka? What are the precautions for wearing Thangka?
1. Thangka should not be exposed to the sun. Thangka after exposure to the sun will make cotton fabric expansion, making the color on the screen is pulled apart, resulting in cracks in the screen. Therefore, we should try to place Thangka at a constant temperature.
2. Thangka should not be placed in a wet place, let alone stained with water. It should be kept as dry as possible, otherwise Thangka will be decolorized.
3. Tangka should not be smoked for a long time. Long term smoking will make the surface of Tangka slightly yellow and look old.
4. If there is dust on the surface of Thangka, you should wipe it gently. Remember not to wipe it with wet cloth or cotton ball, and not to let chemical cleaning agents and other things contaminate Thangka.
5. When Thangka doesn't need to be put out, it should be wrapped with newspaper (newspaper ink can prevent moisture), and then wrapped with plastic film. It's best to store Thangka in wooden box (camphor wood is the best), and put insect repellent, so as to prevent the precious Thangka from being used as' food 'by insects.
6. Thangka should not be stored in a dark box for a long time. It should be taken out once or twice a year to bask in the sun. Especially in autumn, let Thangka bask in the sunlight for 1-2 minutes (avoid strong sunlight), so as to prevent the long-term storage of Thangka and flooding.
