This is the continue version of last blog the history of ink. Ever since the Chinese discovered the technology of paper making (105 AD), they began to actively improve the quality of the ink used for writing. As a result, by the second century AD, the Chinese discovered advanced ink-making technology using gum, gallnuts, oil, and iron salts. It was this technology that guided modern ink-making technology.

AD By the third century the Chinese had succeeded in making solid ink. These ink sticks were dipped in water when writing and then written on. After that, in the eighth century, the bark extracted from the Hawthorn tree was soaked in water for eight days and then boiled until it was well dried by adding wine to the water. It is then packed in specially prepared bags and dried in the sun. Then again wine and iron salts were added to it to bring it to liquid state and used for writing. The ink produced in this way was originally dark blue and gradually became less intense blue.

Also in AD Until the 10th century, carbon, the main pigment used to make ink, was imported to China from India. In this case, Shen Kuo (1031 - 1095 AD), a polymath who became famous in China during the reign of the Song Dynasty, discovered the technology of making carbon with the charcoal obtained by burning petrol. After that the import of carbon, a pigment required by China, from India was avoided.

Johannes Gutenberg, a German expert, made the ink needed for printing presses with iron salts (ferrous sulfate), gum, water, walnut oil, and tobacco around the fifteenth century and established the world's first printing press. This was followed by the addition of solvents, resins, abrasives, pigments and dyes to produce today's modern ink. In the world, ink writing systems started in China, became popular in Japan, reached European countries and then spread throughout the world.

It is no exaggeration to say that Tian did not make any great discoveries but it was only after the invention of ink that the methods of teaching literacy began to move towards a new evolution. Think about it, if only ink had not been invented, today we would have to carry stones to school instead of books. That is why at the beginning of the article I said that ink is an invention comparable to the computer.
