Plant dyeing dye 100g Gobaishi

Plant dyeing dye: gallnut

It is available in 100g portions, making it easy to purchase.

In response to customer requests to sell it in smaller quantities, we have started selling it in 100g quantities.

Chinese galls are a type of gall that form when the Chinese oak aphid parasitizes the leaves of the Chinese oak tree, a plant in the Anacardiaceae family, and the irritation caused by the aphid causes the tannins in the tree to concentrate and swell.
It is also known as "Fushi".
During the Heian period, gallnut was used to dye people black and to blacken their teeth, as well as being used as a medicine.

Only natural fibers such as wool, silk, linen, and cotton can be dyed.
(In the case of synthetic fiber blends, those with a small proportion of synthetic fibers are acceptable.)

[Dyeing method]

For 100g of dyed material

1) Wash the item thoroughly to remove excess oil.

② Dissolve 10g (half) of alum in 4L of 40°C hot water.
Soak the item to be dyed in the alum solution for 20 minutes (pre-mordant).

③ Meanwhile, add 40g of Chinese gallnuts (located in the enclosed non-woven bag) to 2L of water and heat.
Once boiling, reduce heat to low and simmer for 20 minutes, then turn off the heat and remove the oak gallnuts.
Repeat this process twice to make a total of 4 liters of gallnut dye solution.

④ Remove the item to be dyed from the alum solution ②, squeeze it out, and then soak it in the gallnut dye solution ③.

⑤ Heat slowly over low heat to 70℃ and then keep for 10 minutes.
When doing so, move the item from time to time to prevent uneven dyeing.

⑥ Turn off the heat and leave it to set the dye. About 1 hour (3-4 hours if you have time).

⑦ After removing the dyed item in the same manner as in ②, soak it in the mordant solution for 20 minutes to develop and fix the color. (Mordanting)

⑧ Return the item to be dyed into the dye solution in step ⑤ and heat it again.
Heat slowly over low heat to 65°C and then keep for 10 minutes.

9. Turn off the heat and leave to set the dye. About 30 minutes (1-2 hours if you have time).

10. After that, wash with lukewarm water and dry in a well-ventilated, shady area.
