Tansy growing prolifically along the Tarka Trail; tall clumps with rosette grouped flower heads – from my dye plant foraging trip.
Dye Bath Procedure
- Cut up Tansy flower tops and soak overnight in water (pond or river if available)
- Boil up in stainless steel pan, then remove plant dyestuff and allow dye bath to cool to just hand hot. (cotton can be simmered, but silk may get matted if boiled).
- Soak silk for some hours in orange coloured water The colour of the dye bath water is no indication of the final outcome on dry silk. Remove soon if you want a pale colour; leave overnight for stronger colour.
Agitate silk in dye bath occasionally, redistributing evenly in liquid during first 15 -30 mins to ensure all areas are covered when first absorbing dye. Use an upside down lid to keep silk beneath surface.
Silk soon absorbs the dye colour in the strong Tansy dye bath. As this silk can be matted slightly by over heating, and simmering, I only introduce it to a hand hot dye bath. I left it soaking overnight to achieve best strength of colour before rinsing out several times in warm water, until water runs clear.
Wet rinsed silk – drying. Do not squeeze out too hard, or twist creases may occur which don’t completely iron out. In summer silk dries fairly quickly and can be ironed smooth while still slightly damp before any creases set in.
A few dark ‘spots’ are splashes from another dye bath with iron I was doing simultaneously. Only do ONE dye bath at a time.
This lime yellow is very vivid (see comparisons with other gold colours), so I will overpaint with silk dyes or bundle leaf prints. However, it could be useful to over-dye with madder to give a good orange, or with woad for a turquoise blue. The future life of this piece will be posted here….
