Paper was invented by the Chinese during the Han Dynasty and spread slowly to the west . In 105 AD a government official in China named Ts'ai Lun started a paper-making industry. Ts'ai Lun made his paper by mixing finely chopped mulberry bark and hemp rags with water, mashing it flat, and then pressing out the water and letting it dry in the sun. Ts'ai Lun's paper was a big success, and began to be used all over China. By the 400s AD, people in India also started making paper. People all over the world soon began using paper, from India to Spain. But Christian people in Europe were still using parchment. Parchment is made from animal skins. Parchment was even more expensive than papyrus, and so papyrus continued to get a lot of use until the Empire about 400 AD. In medieval Europe, the hitherto handcraft of papermaking was mechanized, the first water paper mill in the Iberian Pensinsula having been built in the Portuguese city of Leiria in 1411. The rapid expansion of European paper production was truly enhanced by the invention of the printing press and the beginning of the Printing Revolution in the 15th century. |
