The English word for paper is from the Egyptian paparus which served the same purpose as paper, but not as light, durable, or flexible. The Chinese word for paper, zhĭ, means “silk from plant fibers.” Cai Lun introduced paper and papermaking to replace tablets of bone or bamboo, which were heavy, and silk, which was expensive. He taught how to separate, in water, fibers from hemp, rags, and the inner bark of mulberry trees and to pour this through a woven cloth to leave a thin mat of fibers to be pressed and dried.
