Thai kozo is our most popular fiber. Grown in Thailand, this fiber from the paper mulberry tree, Broussonetia papyrifera, is identical, botanically, to the Japanese kozo, but growing conditions in a much warmer climate result in a difference in the fiber's characteristics.
Our current supply is little different from last year's kozo. The strips are wider and require a little more preparation. We recommend soaking the fiber in water for a few hours, and then separating the strips by hand into 1/2 inch strips, so that the fiber will cook evenly. We also suggest cooking the fiber for about 4 hours in a 25% solution of soda ash. Paper will be a beautiful tan color.
