harvesting colour – beautiful brown!
I will never see brown with the same eyes again!

Today I finished a batch of alum-treated raw wool and I was ready to try my first experiment with dyeing animal fibre. The alum, you will remember, is a mordant, added to the fibre to increase its colour-fast and light-fast qualities. In some cases, it also makes the colours brighter.

Remember my gathering of Old Man’s Beard lichen? (https://nichepoetryandprose.wordpress.com/2014/03/26/colour-on-the-snow/)

The lichen has been ‘fermenting’ in ammonia about a week and developed a lovely brown colour with tones of orange, reminiscent of root beer.

I sieved out the lichen and added the dye to my dye pot. I added a little vinegar to neutralize the alkalinity since basic solutions can harm the wool. I put about one once of the alum-treated wool into the dye pot and added water, to cover the wool. Then I increased the temperature very, very slowly since sudden changes in temperature can damage the texture and weaken the fibres. I left the dye pot on simmer for about an hour and then left it to cool slowly. Now the wool is drying on the line in my dining room.

The result may seem like an unimpressive brown, but to me it is the most wonderful brown in the world. Reminds me of the ice cream in a root beer float! My first effort at dyeing wool, and obtained from a lichen of the palest green. I feel a poem stirring!
