Why is red ink not easy to fade?

There are many ancient calligraphy and paintings in museums around China, although they are old, the paper is yellow and brittle, but the author's seal left on the calligraphy and painting is still bright and recognizable. This is because the calligraphy and painting are stamped with red ink, which is made of cinnabar and castor oil, mixed well, and some fibrous fillers. Cinnabar is mercury sulfide, a crimson mineral.

Mercury sulfide is very stable and does not react easily with oxygen, so it always retains its bright and ruddy appearance. The color on some old calligraphy and paintings fades due to the oxidation of the pigment and the oxygen in the air to form oxides. , so the red ink made of cinnabar is not easy to fade.

The preparation of ink clay is very particular. Its main components are cinnabar (mercury sulfide), mugwort, castor oil and borneol, which is called cinnabar ink. The quality of the ink is mainly determined by the quality of cinnabar and castor oil.

Among them, cinnabar is a pigment component, and its chemical composition mercury sulfide is a red inorganic pigment, chemically stable, water-resistant, light-resistant, heat-resistant, acid-resistant, alkali-resistant, because of this, it was often used as a pigment in ancient times, and the so-called "vermilion pen" is stained with cinnabar. Some of the red ink clay made by modern people have used some dyes to replace cinnabar, and its bright red color is better than the traditional cinnabar ink, but it is not as good as cinnabar in terms of maintaining the durability of the color. <>

The red ink is not easy to fade because the ink made of cinnabar is not easy to fade. If it is a red ink made of chemical pigments, it will still change color in a long-term light and ventilation environment. Moreover, cinnabar is an inorganic mineral pigment, because the crystal and chemical form are very stable at 300 °C, so the color can be well maintained.

According to historical records, the development of ink clay began in the Wei, Jin, Southern and Northern Dynasties. After the Sui and Tang dynasties, there were silk and paper, so people used methods such as water to mix honey and cinnabar to print seals on paper. This is the prototype of ink.

Because the cinnabar is easy to fall off after the water dries, in the Ming Dynasty, especially in the early years of Yongle, people began to use oil-adjusted cinnabar, and then gradually developed into our current ink.

The main raw materials for the production of calligraphy and painting ink clay come from mineral pigments, vegetable oils, plant fibers, natural spices, traditional Chinese medicine, Seiko inspection, reasonable formula, and hand-kneading. Common cinnabar, cinnabar, etc., the formula of the ink has its own characteristics, and the color is also obvious.

Clay maintenance. After using the ink for a long time, the oil gradually withered, so you can add an appropriate amount of white castor oil that has been stored for a long time and mix thoroughly. However, do not use new oil to prevent the ink from extravasation.

Red is relatively eye-catching, and can highlight the solemn and sacred feeling, so from ancient times to the present day the ink is mainly red, so that the things pointed to are more profound. When we come into contact with ink, we will find that a lot of inks in the society are mainly red, why is the inks not colorful colors? Quite simply, the red ink has the greatest visual impact, which can leave a deep impression on us, and also make us deeply remember the importance of things, and then it has been widely circulated.

1. Red is the most eye-catching among all colors, and the strong visual impact can make people remember related things deeply

In fact, there are many colors of ink in life, especially the colors of ink in the handbook materials, but in daily work, it is mainly red; The reason why the ink clay is mainly red is because the red color is eye-catching enough. Among the colors we know, red has the greatest impact on human vision, so since ancient times, human beings have been extracting red cinnabar to make ink clay and apply it to life; Compared with orange, green, blue, black and other colors, red leaves the deepest impression on people, and it is natural to use red ink.

Second, red can highlight the solemn and sacred feeling, from ancient times to the present day of the ink clay in the red mode in various documents, passed to today

In addition to being eye-catching, red can highlight the importance of something and cannot be replaced by other colors; In ancient times, red was the color of celebration and sacredness, although it was not as golden as the emperor's, but it was an important witness on various documents. From ancient times to the present, everyone regards red as the color of solemnity and sacredness, so in various documents, notices and other materials, red seals will be used; For example, the emperor's edicts will use a red seal instead of a golden seal, which is enough to show the sacredness and importance of red.

Therefore, in order to highlight the importance of things, red ink will be used in daily work.

Because since ancient times, the ink clay used by people is made of cinnabar, and the cinnabar is red, and this ink is not easy to be oxidized, and the color can be maintained for a long time.

The color red is more striking and solemn, and in ancient times it symbolized power.

Moreover, the ancients believed that divine power was related to color omens. Amulets, charms, or divination used in alchemy, often written in red, were considered better and more effective. The emperor's edicts were also often written with a red pen. Red appears more solemn and sacred.

In fact, it has to do with people's ideology. People believe that red will appear more solemn, more eye-catching, and more intimidating, and the ancient seals are also red.

Strictly speaking, the red ink made of cinnabar is not easy to fade, or the color can be maintained for a long time, if it is a red ink made of chemical pigments, it will still change color in a long-term light and ventilation environment.

The cinnabar ink mud color is deep purple red, some people call it purple red sand, it is a kind of cinnabar that precipitates in the lowest layer of the milk bowl when bleaching cinnabar, and the ink mud made of it is bright red with purple, thick and calm, and the most beautiful.

Cinnabar is an inorganic mineral pigment, because the crystal and chemical form are very stable at 300 °C, so the color can also be well maintained, how long can it be maintained basically without discoloration? It is still unknown because the earliest archaeological objects found to use cinnabar for coloring are 7,000 years ago, and the colors are still very bright.

The preservation of the ink mud should not use the purple sand magnet, because it can absorb oil and is easy to dry the ink clay. It is also not allowed to use steel, copper, iron and other metal boxes for storage, because the ink will become black over time due to contact with metal objects. The most important way to store ink is a porcelain jar or jade box, and it should be placed in a cool place.

Tap and lift when using. After each use, the cylinder head should be covered to prevent dust and ash from entering and damaging the color. In addition, the seal should be wiped clean before it can be wetted.

During the storage process, the ink should be turned and stirred with a printing band every ten days or so. Because the cinnabar weight sinks, the oil body is light and floating, and if it does not move for a long time, the sand body sinks and is easy to form a hard block, so the ink mud must be stirred frequently to make it even. As a result, it is durable.
