Wool Dyed with Black BeansNATURAL DYES

Natural Dyes – Black Bean Dye Recipe

I had heard that it was possible to dye yarns using black beans but have never tried it before so last week when I went grocery shopping I looked for some. I purchased a 500 gram bag of Turtle Black Beans from my local Waitrose grocery store. I placed all of the beans into a large plastic jar and covered them with ordinary tap water. Overnight, the beans expanded and filled the whole jar, so then I split the bean solution into 2 jars and added more water. I let this bean stock sit on my kitchen counter for 3 days. The water in the jars started to look quite blue so I was hopeful that this would work. Meanwhile, I spun 100 grams of white wool and divided the wool into 2 50 gram skeins. Alum Mordant I mordanted the wool in a 5% solution of alum and water. (5 grams of alum to 100 grams of wool) I left the wool in the hot mordant for about an hour, then I turned off the heat and let the yarn sit in the mordant solution until cool. I then strained out the dye water from the beans into 2 plastic bowls and placed the skeins of wool into the dye solution. I refilled the bean jars with water, as I am hoping that I will be able to extract more dye from the beans. Wool in Dye Bath This is the wool in the black bean dye bath after about 2 hours.

I let the wool sit overnight in the black bean dye bath – pH 5.

I removed the wool from one of the bowls and added some washing soda to the dyebath to change the pH to 9. Then I put the yarn back into the bath. Almost immediately the colour changed to more of a grey-blue shade.

I am pleased with the results so far. My only concern is whether they will be very colorfast or will fade in daylight. I will put some into a sunny window for the next month to see if any fading occurs. Yes, sadly, the beautiful colours faded badly and turned gray. Natural Dye Recipes Tin Mordant Alum Mordant
