Hadaura kozo paper is a traditional Japanese paper made from fibers of kozo, a plant in the mulberry family. Here are the steps of its production:
Harvesting: The kozo plant bark is harvested in the autumn when the sap is concentrated in the roots and branches.
Soaking: The bark is soaked in water for several hours or days to soften it.
Boiling: The bark is boiled in water with wood ashes to remove the bark and other organic matter and to make the fibers more supple.
Washing: The fibers are then washed in clean water to remove the ashes and impurities.
Beating: The fibers are beaten with wooden mallets to separate them and make them finer and more uniform.
Sheet formation: The fibers are mixed with water to form a suspension, then spread on a bamboo screen to form sheets of paper. The sheets are then pressed to remove excess water.
Drying: The sheets are dried in the open air or in the sun.
Finishing: The sheets may be coated with starch or glue to make them stronger and more water-resistant.
The final result is a lightweight and durable paper with a unique texture that is often used for calligraphy and traditional Japanese art.
