The reason why "A Thousand Miles of Rivers and Mountains" can be passed down for thousands of years is still colorful and dazzling, which is related to the pigments used.
First of all, we must first understand how Wang Ximeng drew the "Map of a Thousand Miles of Rivers and Mountains"?
The first time, I will paint a landscape painting with ink.
The second time on the red (ochre color), for the back of the green to make the padding, cold and warm contrast, make it more vivid.
The third time on the stone green (turquoise or malachite).
The fourth time, another layer of green is superimposed.
The fifth time on the cyan, that is, the "blue" that is better than the blue out of the blue. After the fifth painting, it is equivalent to drawing a 11-meter long scroll five times.
Among them, the mineral pigments used are——
【Stone blue】Azurite and lapis lazuli
Green is taken from blue, and blue is from blue. Shiqing, also known as azurite, the chemical formula is: Cu3 (CO3)2(OH)2, crystalline carbonate minerals of the monoclinic crystal system. The crystals are columnar or thick plate-like, usually granular, stalactite, shell-like, and earthy aggregates. Dark blue, glass luster, earthy blocks are light blue, glossy dull. It is closely symbiotic with malachite and is produced in the oxidation belt of copper deposits, which is a secondary product containing copper sulfide oxidation. Shi Qing has split heads, two, three, and four greens.
【Stone green】Turquoise or malachite
Stone green, also known as malachite, the main ingredient is basic copper carbonate, the chemical formula is: CuCO3 · Cu(OH)2。 Malachite gets its name because it resembles the green color on the spots of peacock feathers and is a monoclinic crystal with a cylindrical or needle-like crystalline shape. The colors are emerald green, grass green and dark green. The low hardness is suitable for grinding into toner. Due to the extremely low tortuous rate of stone green, and the stability is excellent, it has the characteristics of bright hair color and long-lasting preservation, and is widely used in the world.
Symbiotic with malachite
Turquoise, an aqueous copper aluminate mineral with the chemical formula CuAl6(PO4)4(OH)8·5H2O. Turquoise also varies in color depending on the elements it contains, and it is blue when it contains copper in the oxide and green when it contains iron. It is mostly sky blue, light blue, greenish blue, green, and greenish pale. The color is uniform, the luster is soft, and the quality of those without brown wire is the best.
【Red】Ochre and cinnabar
Ochre is an oxide-based mineral corundum hematite, which mainly contains iron trioxide (Fe2O3), and is mostly irregularly flattened. Dark brownish red or grayish black, striped cherry red or reddish brown, some metallic.
Cinnabar, a mercury sulfide (HgS) mineral. The color is often red, and the surface of the crystal is streaked red and translucent. Pure tatsu sand is diamond luster, vermilion red, dull luster when containing impurities, brownish red.
【Yellow】Female yellow
Female yellow is a monoclinic crystalline ore, the main component is trisulfide arsenic, the chemical formula: As2S3, is highly toxic. The female yellow color is lemon yellow, the stripes are bright yellow, translucent, and the diamond luster is to greasy.
【White】Brick
Bricks: It is a bivalve marine animal. It is the largest bivalve shellfish in the ocean, known as the "shell king", the shell is thick, the shell edge is like a tooth, the two shells are of the same size, the inner shell is white and smooth, and the white is as white as jade.
As netizens commented, from the famous painting "A Thousand Miles of Rivers and Mountains" to the dance "Only This Green", the elegant and beautiful Chinese aesthetics have created a dream that spans thousands of years, activating the traditional cultural genes in the hearts of the audience. Behind this, there is also the accumulation of the exquisite magic of ancient Chinese science, waiting for us to inherit and carry forward.
