Problems solved by technology

[0009] Generally speaking, the substances in Thangka must have molecular volatilization, including the pigments painted on the canvas. However, due to the color requirements, the raw materials of the existing pigments are not easily accepted by the human body. plants, the process of volatilization of such plants will produce odors that are not acceptable to the human body

Embodiment Construction

[0032] Pigment preparation method of the present invention, make primary color according to following process,

[0033] Take fresh saffron, put it in a cool place for 2.5 hours, then place it in a dryer at 100 degrees Celsius to dry for 0.8 hours, and keep turning it during the drying process to make the water quickly evaporate to a water content of less than 8%. The powder is passed through a 300-mesh mesh, and placed in a light-shielding vacuum box for later use.

[0034] Take fresh comfrey, lay it in a cool place for 2.5 hours, then place it in a dryer at 110 degrees to dry for 0.7 hours, and keep turning it during the drying process to quickly evaporate the water to a water content of less than 8%. The powder is passed through a 300-mesh mesh, and placed in a light-shielding vacuum box for later use.

[0035] Take cinnabar with a water content of less than 8%, grind it finely through 300 mesh, and set aside.

[0036] Place 40 parts of saffron fine powder, 10 parts of com...

Abstract

The invention provides a preparation method for pigments used for painting a thangka. According to the invention, base colors are prepared according to the following steps: taking fresh saffron, lithospermum and cinnabar and carrying out drying and beating into powder, then uniformly mixing the obtained fine powder and adding a cementing agent, and adding oxygen-removed purified water so as to prepare a red pigment; taking polygonum tinctorium leaf extract and carrying out concentration, and adding the cementing agent so as to obtain a blue pigment; and taking refined gamboge resin and carrying out fine grinding, then adding the cementing agent, and adding the oxygen-removed purified water so as to obtain a yellow pigment. The invention provides a production method for the pigments used for painting the thangka by using plant raw materials. The plant pigments provided by the invention can keep bright color for a long time under the conditions of no valuables like gold and silver. The pigments provided by the invention have significantly weak pigment molecular volatility and significantly slow color fading degree, wherein the color fading degree of the pigments in the invention is reduced by nearly 30% than the color fading degree of traditional pigments in prior art.

Description

technical field [0001] The invention relates to a preparation method and formula of a special drawing pigment for Thangka of Tibetan culture. Background technique [0002] Thangka is similar to scroll painting, mainly painted on cloth or paper, and then sewn and mounted with silk and satin. [0003] The existing pigments used in painting thangkas are all taken from natural materials, with natural minerals and plants produced in the snowy region as the main raw materials for production. They are of excellent quality, pure in color, excellent in light resistance and strong in weather resistance. The specific materials used include silver, gold, coral, pearls, gemstones, saffron, madder, agate, rhubarb, etc. The precious materials used are rare in the history of world painting. Using this kind of precious pigment to paint portraits has gorgeous colors, bright and dignified colors, distinct and magnificent patterns, and has the advantages of long-lasting, not easy to fade, and ...
