This is a straightforward way to make ink and can be used for a variety of plant material. In this demonstration we are using yarrow tops from the dye garden at Grand Parade.
3. Cook at a simmer for at least 15 mins.
5. Put the plant material back in the cooking pot with fresh water and heat up again and cook another 15 mins or so as before.
(Rinse and repeat. This is a process you can repeat until all the colour has been extracted from the plant material. I usually find twice is enough.)
6. Put all the used plant material in another bucket. When it has cooled down it can be taken out to the compost heap in the dye garden.
6. Pour the coloured liquid back into the stainless steel pan and heat up again. With the lid off the pan, keep the heat on so that the liquid is just below boiling point. Slowly, allow the liquid to evaporate so that the colour of your ink gets stronger.
Please clean up and tidy everything you have used in the dye lab.
