Homeland paper
country where invented paper, which we use to this day, gave the world the porcelain, the compass, gunpowder, fireworks.This, of course, China.And if the names of the inventors of "precursors" a sheet of paper - papyrus scrolls and tablets - remain unknown, the name of the person who invented paper,
country where paper was invented, not planted with birch groves.Here grow mulberry tree, bamboo and rice.Cai Lun rastolok fibrous bark of the mulberry tree.Mix the resulting mixture with water, hemp and wood ashes, and then placed on a bamboo frame with a lattice.Smooth out the resulting layer by a stone and dry in the sun.That's what got the first sheet of paper.Over time, the technology of manufacturing improved.The mixture was invented by Cai Lun, began to add starch, silk fibers, dyes, which greatly improved the quality of the paper sheets.
All the secret becomes clear
people east of the country where invented paper, carefully kept the secrets of its production.However, many centuries ago, Chinese merchants traveled with their goods around the world.Caravan, arriving in a new city, talking, sharing news.Returning to his native land, they brought news from over seas.It was something like a global communication.And somehow in Samarkand Arab merchants to find out the secrets of paper making and learning brought him to Spain.The paper is started to do in 1150.Soon the technology of papermaking was known in all European countries.
paper production in Russia appeared only in the second half of the 16th century.Sources report that in Moscow in the 16th century, there were 10 paper mills, 50 companies, where they made manually paper and cardboard.
