Natural dyes, experimenting with black beans

June 10, 2016

Last weekend I began experimenting with natural dyes, and had mixed success. I hoped to try onion skins next because I wanted a bright orange, but haven’t had time to gather together enough onion skins. Nevertheless I’ve got the bit between the teeth now, dying with natural dyes from plant materials is like alchemy.

I love that lavender blue colour I call Eeyore blue. I once saw a picture of some lace which had been dyed using black beans which was just that glorious colour and decided I was going to experiment with it myself. Black beans can be found with the chick peas and kidney beans on supermarket shelves.

The black beans were soaked in cold water for 24 hours, they produce a rather gloomy, murky mauve coloured liquid. Not very promising I admit. But then comes the alchemy.

I drained off the soaking liquid from the beans, added a length of fabric which had previously soaked in Alum mordanted water and presto, the magic began… not mauve but a lovely purply blue began to develop.

Just to test how strong the dye stuff was I put the beans back in another jar, topped up with more water and added more fabric. I left both jars soaking for a couple of days. The result was a lovely purply blue fabric, and a paler version with a rather more tie dye effect, caused by the lack of space in the jar for the beans, the liquid and the fabric.

This is such an easy process, no heat, no chemicals, and if I hadn’t reused the beans as a dye stuff, I could have cooked and eaten the beans, so no waste either, and the colour is divine. I love it, love it, love it.
