Cai Lun was said to have improved the papermaking process by using tree bark, hemp, rags, and fishnets as raw materials. He boiled these materials in water to create a pulp, which he then poured onto a mold and pressed flat to form sheets of paper. The sheets were then left to dry in the sun. Cai Lun's papermaking process was revolutionary at the time and paved the way for the mass production of paper in China.
Paper was used in China for various purposes, including writing, printing, packaging, and personal hygiene. It was later introduced to other parts of the world through trade and cultural exchange. By the 14th century, papermaking technology had spread to Europe, the Middle East, and North Africa.
The invention of paper had a profound impact on human history and culture. It facilitated the development of writing, bookmaking, and the spread of knowledge. Paper also became an essential material for various artistic and creative pursuits. The availability of paper made possible the production of large quantities of books and other printed materials, contributing to the advancement of education and literacy worldwide.
