The so-called desert paint is the exposed desert area of gobi bedrock. Due to the rise of groundwater, evaporation often leaves a layer of red-brown iron oxide and black manganese oxide film on the surface of the stone body, like a layer of paint, so it is named desert paint. Because the Gobi region is very dry, the groundwater salinity is very high, in addition to a variety of salts, water solution also dissolve high concentration of iron oxide and fierce oxidation. Due to the high salt content, water evaporation is blocked by the gravel resting on the ground, forming many dew-like water spots on the gravel bottom. At the same time, the desert stone is very dry, desperately absorb, so that these minerals not only stay on the surface of the stone, but also into a certain depth of the stone, forming all kinds of beautiful pictures, like lakes, mountains of water, and the shape of various living things map stone. The surface of the joints and fissures of various gravel and primary rock in the Gobi area, especially the bottom surface, often has different degrees of desert lacquer. The gravel was moved by the Gobi storm and grinded by sand, making the picture more delicate and full of lasting appeal.
Desert paint can be divided into landscape painting (Chinese painting), oil painting, hazy painting, biological graphics, etc. According to the rock of the carrier, there are SLATE, limestone, granite, volcanic rock, agate, jasper, opal and so on. The ornamental and collection value of desert lacquer is beautiful picture and vivid shape. In terms of stone quality, the harder the carrier rock, the higher the collection value. Desert paint is not uncommon, but what is rare is the novelty of the picture. It is similar to the tree stone, to do the hard rock painting on the best, if can be agate, opal and other transparent minerals or rock wrapped, is the best, double the value. The discovery of desert lacquer was described in Yunlin Shi Pu by Du Wan in the Song Dynasty.
