Spread of paper

People in Japan learned how to make paper with fibers of the mulberry tree, around 610 AD. This is called Japanese paper or Washi. The Chinese invention spread to India, and then to the Middle East, and then to Italy.

An opportunity occurred after The Battle of Talas in 751. Then an Arab army captured soldiers of the Chinese. There were some paper makers among the captured soldiers. From them, paper-making spread throughout the Islamic world. In 757, a paper mill was built at Samarkand. People learned to use linen as paper raw material and to use starch made from flour as an additive.

The Italians used hemp and linen rags. In 1276 the first Italian paper mill was built at Fabriano and, until the 14 century, Italy was a paper supplier in Europe. In 1282 the first watermark was introduced in Bologna.
