A dispersion of Cellulose fibers in water. Paper manufactured before the 1850s was made primarily from Cotton and Bast fibers obtained from Linen, Flax, Rags. Due to shortages of these materials, other raw materials for paper pulp were common, but usually not as successful. In 1854, a process was patented for the production of paper pulp from Wood. This led to the mass production of inferior papers before methods were improved.
