This year it was spring when the temperature did not rise easily, but in June, if the weather was fine, the temperature exceeded 20 degrees during the day, and the dye plants in the garden grew. This year, I plan to make woad balls from woad I sowed last year, and then ferment the woad balls that I made last year, fermented and dried for the second time to make couched woad
Last year, a new species of indigo-reducing bacteria was analyzed and certified from Woad-Indigo vat(couched woad + indigo cake + wood ash lye+ wheat bran) liquid in North-Indigo Textile Arts Studio. (February 14, 2022)
Fundicoccus fermenti sp. nov
Fundicoccus fermenti sp. nov., an indigo-reducing facultative anaerobic alkaliphile isolated from indigo fermentation liquor used for dyeing
In the morning, the outside temperature is -12 degrees Celsius, the indigo liquid temperature is 25 to 28 degrees Celsius, and the room temperature of the dyeing place with glass on three sides is 7 degrees Celsius when it is cloudy and 18-20 degrees Celsius in the daytime when it is sunny. There is 1m of snow outside, and icicles and snow dance behind the glass. Milky white woolen cloth from the Occitanie region of France is dyed green by the water-soluble leuco indigo reduced by indigo reducing bacteria. When the cloth is removed from the indigo liquid, it gradually oxidizes with oxygen in the air and turns into indigo, which turns indigo. Color contrast is strong in winter.
Indigo vat dyed 30 kg of Scottish Cheviot and Australian Merino in 2019, and 4 pieces of 122 cm x 122 cm in 2020, and this time dyed Finnish wool. Delicate, long hair, oily raw wool, finished in my favorite indigo colour.
