BOTANICAL DYES
2018 - ongoing
An on-going experiment in dyeing with natural materials as a way for me to learn more about plants. These swatches of fibre have been dyed with either purchased plant extracts or wildcrafted plants from coastal British Columbia.

RED ALDER (ALNUS RUBRA) + STAGHORN SUMAC (RHUS TYPHINA)
Source: wild-crafted
Fibre (Left to Right): superwash wool, wool, silk, cotton
Mordant: alum (wool, silk), alum acetate (cotton)
Preparation:
- Bark ground to saw dust, used 600% WOF.
- Bark simmered with sumac berries (600% WOF) and baking soda until dye bath reached PH8.
- Dye bath simmered 3 hours then strained.
- Divided dye into two pots, one with dye bath as is, and the second with iron at 16% WOF. Each pot simmered 1 hour.
Observations:
- Adding more baking soda did not affect the PH.
- Try using a more alkaline solution to try for a black dye.
- I'm not sure if the tannins from Sumac aided in the dark colour or if this was only due to the PH.
