Plant cultivation and use

Phellodendron sachalinense is a deciduous tree which can reach 15m high with irregular branching.

It has a rapid growth. As it is hardy and can thrive in various soils but prefers sunny exposure. Clumped flowers are yellow. Flowering occurs in early summer. It is often considered as geographical variety of Phellodendron amurense but it differs to it in its thinner layer of cork; like it, its fruits yield an oil which insecticidal properties are similar to those of pyrethrum.

Phellodendron sachalinense has dyeing properties conferred by the alkaloids it contains (mainly berberine).The color varies from pale yellow to brown depending on the concentration.

Phellodendron amurense and Phellodendron sachalinense are both used for the same purpose. It is possible to distinguish them by analysis of the proportions of the alkaloids.

Preparation process for making paper

China:

The outer bark of Phellodendron, chopped into pieces is placed in a bag, soaked in water and boiled; then the filtrate, a bitter yellow liquid, is collected by pressing the bark.
The residues are crushed and boiled again, three times and the filtrates of the three baths are mixed. This allows for a bigger quantity of liquid and a less saturated color. This liquid is called Huang po.
The paper to be dyed must be unsized to let dye penetrates better. The paper after dyeing has a glossy appearance.

Japan:

Wood is cut in small pieces and boiled. The extract is filtered before dyeing.

Dyeing of paper is performed in two ways: pulp dyeing (sukizome) or sheet dyeing (hitashizome by dipping or hikizome by brushing).

To dye paper by soaking, the sheets are plucked one by one between two wooden sticks by the small side. This will keep the sheet flat during soaking.

Korea:

Wood is cut in small pieces and boiled. The extract is filtered before dyeing.

Papers dyed with Phellodendron amurense are fixed by etching with tannins extracted from the bark of chestnut or oak acorns.

The papers are dyed in three ways: dyeing of the pulp (Seonyeombeop), dyeing of the sheet by dipping, brushing and spraying (Huyeombeop ), combination of the both methods (Honyeombeop). Then the paper can be hammered.
