Rice-paper

Rice paper is a product made of paper-like materials from East Asia made from different plants. These include:

In Europe, around the 1900s, a paperlike substance was originally known as rice paper, due to the mistaken notion that it is made from rice. In fact, it consists of the pith of a small tree, Tetrapanax papyrifer, the rice paper plant (蓪草).

The plant grows in the swampy forests of Taiwan, and is also cultivated as an ornamental plant for its large, exotic leaves. In order to produce the paper, the boughs are boiled and freed from bark. The cylindrical core of pith is rolled on a hard flat surface against a knife, by which it is cut into thin sheets of a fine ivory-like texture.

Dyed in various colours, this rice paper is extensively used for the preparation of artificial flowers, while the white sheets are employed for watercolor drawings. Due to its texture, this paper is not suited for writing.

This "rice paper", smooth, thin, crackly, and strong, is named as a wrapper for rice, and is made from bark fibres of the paper mulberry tree. It is used for origami, calligraphy, paper screens and clothing. It is stronger than commercially made wood-pulp paper. Less commonly, the paper is made from rice straw.

Depending on the type of mulberry used, it is named kozo (Broussonetia papyrifera, the paper mulberry), gampi (Wikstroemia diplomorpha), or mitsumata (Edgeworthia chrysantha). The fiber comes from the bark of the paper mulberry, not the inner wood or pith, and traditionally the paper is made by hand.

The branches of the paper mulberry shrubs are harvested in the autumn, so the fibre can be processed and the paper formed during the cold winter months, because the fibre spoils easily in the heat. The branches are cut into sections two to three feet long and steamed in a large kettle, which makes the bark shrink back from the inner wood, allowing it to be pulled off like a banana peel. The bark can then be dried and stored, or used immediately. There are three layers to the bark at this stage: black bark, the outermost layer; green bark, the middle layer; and white bark, the innermost layer. All three can be made into paper, but the finest paper is made of white bark only.
