Jenny’s experiments with fermentation dyeing.
 I think this must be the slowest form of dyeing as it is done cold. I started with weld which wasn’t very successful, but red cabbage has been very exciting.
I chopped up a quarter of a red cabbage very small and put it in a clean plastic milk bottle with the lid on. I shook it 3 times a day and let out the gasses, it was kept in the dark and after 4 days this was the result.

I know that red cabbage is very sensitive to the PH, so I tried painting the silk with washing soda, that is an alkaline ph.

This was quite a startling colour, and so far after a month it hasn’t changed. so then I tried lemon juice, this goes a very pretty pink, but it did tend to rinse out.

Iron water made from [ferrous sulphate] turn the silk blue and does seem colour fast at the moment.

finally I did a black berry leaf print, not such a good result.

I shall have to see how the colour lasts, red cabbage is notoriously good at fading, the idea is that the fermentation will help the colour to stay.
  Now I have started 2 more one with buckthorn bark, I have kept the PH high by adding slaked lime, this took much longer about 3 weeks but I am pleased with the red colour.

I now have a birch bark vat going, it is supposed to make pink, but after nearly 3 weeks I am not sure yet.
