My last dyeing session left me with a pot of turmeric dye (about 6 cups of water plus 3 heaping tablespoons of turmeric and one tablespoon of alum) that was just begging for me to do something with it! I had recently seen an online post that said that if you add iron to turmeric dye it will “sadden” or darken the colors. It also said that you can get olive green colors by doing this…which peaked my interest.
I had two options to sadden my dye. The first was iron powder that I had purchased from Dharma Trading. The second was a homemade brew that was created by submerging one pad of extra fine steel wool (0000) in vinegar and letting it sit until the steel wool dissolved. This typically takes about two days. However, since mine was leftover from another project it had been sitting for several months, so it was good to go!
My understanding was that it would only take a small amount of iron to alter the color. So I put my.pot on the stove, turned the heat to med/high and added 1/2 teaspoon of the iron powder.
Hmmmmm, well it was really pretty but it didn’t look “sad” at all? I then added another 1/2 teaspoon and I waited. Nothing. Okay, time to give my concoction a go. I added approximately 1/2 cup of my brew and I waited. This time I was getting somewhere. After another 1/2 cup addition of my homemade iron solution, this is what I got.
It was definitely looking more “sad” although it didn’t exactly look olive green. Since I had already added a good amount of iron to the mix, I chose to proceed.
Now it was time to address my fabric. I decided to use two silk scarves and some simple shibori techniques to create patterns on the fabric. I folded both scarves into a triangle shape as follows:
For some odd reason, this particular triangle fold has always been difficult for me to wrap my head around?! Hopefully it will be easier for you! I started by folding my scarf in half and then (as you can see above) I folded it past the edge of the fabric. Next I folded it back onto itself to create a triangle. Last, I folded the whole triangle back and forth (accordion style) until I reached the end. I followed the same procedure for the second scarf and then I gave each of them their own personality. For one, I used three extra large popsicle sticks that I bound with rubber bands to create a resist. For the other, I simply tied a row of rubber bands down the length of the triangle.
Into the dye they went! I simmered them on low for one hour and then I turned off the heat and let them soak for approximately 3 hours.
Next, I rinsed them in cold water until the water ran clear. There was very little excess dye coming off of the fabric which told me that the fabric and the dye bonded well. Unfortunately, the olive green that I was hoping for was nowhere to be found. But the color was definitely altered and is more of a mustard yellow than the bright sunshine yellow that I got from the turmeric dye alone.
This brings me to the subject of colorfastness and washfastness. After doing a TON of research online (seriously, I could write a dissertation), I learned that while turmeric dyed fabric is very washfast it is not known to be lightfast. Although using mordants such as alum and iron will most certainly help with both wash and lightfastness, I have been unable to determine the extent to which this is true. This is my third foray into turmeric dyeing and I can tell you that my colors are holding fast so far. The fist piece of fabric that I dyed is now about 5 months old and I can see no discernible fading. I would be very interested to know if anyone has had any longer term experience with turmeric dyed fabrics, especially when an alum mordant was used. Please comment below if that’s you!!!
After air drying and a good ironing, here are my finished pieces.
I really like the one on the left and I’m not so sure about the one on the right. The pattern is kind of interesting, however, the color is blotchy and uneven. I am a fan of the mustardy yellow though and it was interesting to see what the iron did to my dye bath. All in all it was another informative adventure down dyers lane. I hope that you enjoyed the ride as much as I did! Please feel free to comment or ask questions. To see the scarf on the left in my etsy shop, go here. 🙂
