Harvesting kozo trees (kozo is deciduous shrub).
The harvesting time is during December and January
Cutting the branches into the same length and steaming (about 3 hours).
After steaming, dividing into the core and the bark.
Stripping onikawa (the 1st bark layer) and amakawa (the 2nd) with a spatula to get sirokawa.
(Washi is made from the shirokawa of kozo.)
This process is also called “kazuhiki” or “hyohitori”.
Bleaching shirokawa naturally by placing it in water.
Then boiling it in a pot (about 3 hours) to pick out only pure fibers.
(Adding soda ash to remove impurities and to soften the fibers.)
After that, placing the fibers in water again to remove the lye.
Removing impurities and flaws from the shirokawa.
Removing small “chiri” (dust) from each fiber carefully.
This process is also called “chiriyori”.
Beating shirokawa with a wooden stick to untangle the fibers.
These disentangled small fibers are called “kamiso” (the source of paper).
How much disentangled the fibers are becomes clear when they are put in water.
Recently, this process is sometimes done with a machine.
Neri plays an important role to degrade kozo fibers equally under water.
(If it is only water, fibers sink to the bottom).
Using a mucilaginous material extracted through beating the roots of the Troro aoi plant.
Putting the beaten shirokawa and neri into sukibune (paper-manufacturing container) and stirring them.
The process of suki is spreading out the shirokawa fibers in water flatly on “su” (the mat made of split bamboo, reeds, and silk thread tied together), which is put between “keta” (the wooden flame).
There are various ways to make paper, such as nagashizuki, tamezuki, nagashikomi, etc.
Washi contains some water right after being made and this state is called “shitogami” (wet paper).
Then placing shitogami one by one.
This piled up state is called “shito” (the paper bed).
Sandwiching and pressing shito with a compressor to wring out its water.
Then peeling each shitogami off and putting it on a board with a brush to dry naturally.
(Neri makes it possible to peel piled up paper off cleanly.)
There is another way to dry paper, like putting it on a hot iron plate.
When it is dried, it is then inspected for flaws and dust.
Now it’s all done!
