Floss silk has sericin remaining and is compatible with indigo. After dyeing, it is well oxidized, dyed and oxidized repeatedly, and soaked it in water. And then, rinsed it with lukewarm water. The dyed colour did not return to water. Dry in the sun in a short time.
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.
