INDIGO: Persicaria Tinctoria, Dried Leaves for Dye Vat, Fresh Leaves Extraction, Compost (sukumo) for Quick Vat with Michel Garcia 2-Day Workshop (Saturday 1 of 2)
September 11, 2021 @ 9:00 am - 12:00 pm
This workshop is for those who love Persicaria tinctoria and for many who grow them. Michel will explore this indigo plant demonstrating a rare method using dried leaves of persicaria to start a dye vat. In addition, he will cover how to obtain indigo pigment/dye from fresh persicaria leaves by water extraction method, and how to make a dye vat with a quick method using the compost form (sukumo) of this plant.
Persicaria tincoria*, previously Polygonum tinctoria is commonly, erroneously called Japanese indigo. It was already in use in the Western Zhou period (1045 – 771 BC) in China and was the most important blue dye in East Asia until the arrival of Indigofera from the south. It is uncertain when the plant reached the Japanese archipelago. There are other indigo plants found growing and being used for blue dye in Japan including strobilanthes cusia in Okinawa. Strobilanthes is grown in moist wooded places, sometimes cultivated; 100-2000 m. Fujian, Guangdong, Guangxi, Guizhou, Hainan, Hunan, Sichuan, Taiwan, SE Xizang, Yunnan, Zhejiang, and Bangladesh, Bhutan, India, Laos, Myanmar, Thailand, Vietnam.
The workshop will take place on two Saturdays, 3 hours each on 11 and 18 September 2021 with a week in between to experiment with your own indigo, persicaria tinctoria, or strobilanthes cusia. For those who wish to follow Michel in your home studio, you must have 1kg of your own dried leaves of persicaria or strobilanthes. Please source them yourself. Many enthusiasts grow persicaria and have a stash of dried leaves. If fresh persicaria is not available, Michel will cover the process utilizing fresh woad as well.
Saturdays, 11 & 18 September, 2021 | 9:00 – 12:00 PST/ 18:00 – 21:00 France
