Korean paper or hanji (Korean: 한지) is the name of traditional handmade paper from Korea. Hanji is made from the inner bark of Paper Mulberry, a tree native to Korea that grows well on its rocky mountainsides, known in Korean as dak. The formation aid crucial to making hanji is the mucilage that oozes from the roots of Hibiscus manihot. This substance helps suspend the individual fibers in water.
Traditional hanji is made in laminated sheets using the we bal method (a sheet formation technique), which allows for multi-directional grain The process of creating hanji also employs dochim, a method of pounding finished sheets to compact fibers and lessen ink bleed.
In Korea, papermaking started not long after its birth in China. At first, made crudely out of hemp and ramie scraps (called maji; Korean: 마지), hanji developed to the point that it was renowned as the highest quality paper available in East Asia. Its origins in Korea are believed to fall somewhere between the 3rd century and the end of the 6th century. In 1931, a piece of hanji was found at an archeological dig at a tomb site from the Lelang period (108 BCE–313 CE).
