Boletopsis mushroom dye

Alum Mordant

3 litres water
25 grams alum
10 grams cream of Tartar

100 gram wool yarn tied in skeins
Rinse the clean washed yarn in cool water
Add the yarn into the cool mordant bath and bring it to 80-90 C degrees

Mushroom Dye Bath
If using dried mushrooms soak them in water for a few hours until soft.

200 grams dried mushroom fungi
5 litres water
Bring to boil and simmer for 2-3 hours

Let dyebath cool
Strain the liquid and store the cooked mushrooms.
They can be used again in an afterbath

Add mordanted yarn to strained dyebath liquid

Return to heat and simmer for 1 hour at 80-90 degrees Celsius or longer for stronger colour.

Remove from heat source and let cool

Rinse in water that is of similar temperature as dyebath to avoid shocking the yarn and causing felting to occur.

Boletopsis Grisea Dye Recipe
I tried this fungi dye recipe again using less mushrooms as I didn’t have 200 grams of boletopsis fungi available. This produced a lighter shade of sage green.

20 grams dried Boletopsis grisea mushrooms.
Cut them into small pieces and put inside a nylon stocking.
Put into a crock pot filled with 3 liters of water.
Bring the dye mixture to a simmer and let it cook for a few hours.
Turn off the heat and allow the dye mixture to cool and sit overnite.

Reheat the dyepot the following day.
Check the pH of the dyebath and add ammonia to bring the pH to 8-9.
Add 100 grams of alum mordanted wool yarn.
Let the dyebath simmer for several hours until the yarn has absorbed the dye colour, checking the pH levels from time to time.
Turn off the heat and allow the dyebath to cool.
Remove the dyed yarn and rinse in cool water.

I've had an interest in weaving, looms, yarns and textiles since I was a small child. I learned to knit, crochet, sew, do needlepoint at my mother's knee. My grandmother was a Saami from northern Norway. I am very interested in studying more about tradtional Saami and Finnish style weaving and handicrafts. Paivi Suomi
