To
obtain a dye, the lichen is soaked in a 2 – 2 ½ % ammonia solution for
two or three weeks in a sealed container. It should be kept in a warm
place.
Test the solution after that time and if a bright pink colour appears on some fiber, the dye is ready. Warm the dye to approximately 70 degrees C. Soak fibre in dye for 10 minutes. Remove from dye and place in a sunny position. On exposure to sunlight, dye should change to blue. The stronger the sunlight, the quicker the change occurs.” |
