Natural Dye Experiment: Black Beans

I've been trying lots of new plants for natural dyes for my installation.  Between the river trail and the nearby markets the Strip District of Pittsburgh provides a bounty of color.  Even so, getting a nice true strong green is very difficult.  My best chance is going to be getting a blue and over dying with yellow.  So I've been experimenting with black bean soaking water and getting good results. Below are some images of the process using a silk scarf:

First I soak black turtle beans in water over night. I use about twice as much water as black beans, and stir ever so often as I walk by. Then I scoop the now dark purple water off the beans and into a bucket to dye in.  (The beans made delicious burgers).

 I added a splash of vinegar to the dye bath, since silk as a protein fiber tends to take up color better in a slightly acidic bath.  This also has the effect of turning my dye a brighter, magenta purple.

And here is the scarf after spending the night in the cool black bean dye.  Very pretty magenta, but not the blue that I'm looking for.  To correct this I have to adjust the PH back to the other side by soaking it for a few minutes in a water and baking soda solution.  Its pretty amazing to watch actually, as the color changes right before my eyes.  Here it is after just a few seconds in the baking soda wash.

 The final color is this beautiful steel blue.

 I've got about a half a pound of wool still in the dye, since it doesn't take up color as quickly at cool temperatures as the silk.  It will spend another night in the dye, and once I take it out tomorrow I will be able to over dye the blue wool with some yellow from turmeric and hopefully get a nice range of greens for my installation.

 Sometimes it seems like I don't get very far in a day, but looking between my last post and today's images is reassuring.  I spent over a week making all the little fiddly bits in the center of the side counter, and I will probably still add a bit more.  For the time being however I've moved onto bigger (and better?) areas.  I'm starting to work my way across the front of the space.

I'm getting especially excited about the way its beginning to drip over the front side here.

Just a quick update on the progress of the installation at SCC.  I've been making lots of felt and dyeing lots of wool.  The bright yellows and oranges are coming from turmeric, and I've gotten a pale minty green from spinach and a blue/grey from black beans, all sourced from the markets just around the corner from SCC in the Strip District of Pittsburgh.  Its been a lot of fun exploring the city and my to-do list just keeps getting longer.

I've just finished the first week of my residency at Contemporary Craft here in Pittsburgh.  I'm working on a fiber installation that's inspired by natural processes of decay. The installation will grow over time to completely engulf the space by the end of August, and is made up of a couple different components. One component is made up of these felted cup forms inspired by moss, lichen, and mold, shown here at the end of day two:

There just so happens to be this lovely tree outside my workspace, which provided me with my color palette. I'm doing a bit of natural dying using locally foraged plants to get some of my colors.  Shown below are samples dyed with a mixture of Queen Anne's lace and Golden Alexander, using Iron and Copper Mordants. 

This yarn is going to be used for another component of the installation, a large vine that will grow across the back wall and into the space, which just got started today.

 I'm hoping to make weekly updates on the installation as it grows, so check back often, or follow the Contemporary Craft Tumblr which will also be posting updates.

Stitching with Wire

 Besides the large woven panels, I've been exploring stitching on paper with wire.  I'm looking at the tangled wire floats I achieve through weaving and trying to get the essential chaotic breakdown of structure in another medium.

Deterioration Panels - New Weavings

 I have a few new large weavings that have been hanging around the studio...

 Deterioration Panel I. Mercerized Cotton, Iron Wire, Cottolin, rusted with saltwater. 80" x 28"

Deterioration Panel II. Mercerized Cotton, Iron Wire, Cottolin, rusted with saltwater. 24" x 80"

 

Salt crystals that form during the rusting process, beautiful in their own right.
