Yesterday, I tried to dye with red onions and....it was a fail. I should have read Rebecca Desnos' blog post before starting on my own dye pot. Instead, all I got was brown. A lovely, soft brown with a reddish tinge in the case of the alum mordant wool but brown.
The linen pretty much didn't dye. The alum linen (top of the photo) does have a very slight burnished green hint to it. The natural linen I used an iron mordant (bottom of the photo) on is still...natural. The alum mordant wool is almost an auburn/light brown color and probably will make a funny winter hat for next year. The iron mordant wool just looks blah. Parts where there was still iron on the yarn (I didn't rinse it and that really showed) are dark gray to almost black. So, maybe, it might make a good black if I use iron water in the dye pot?
Above is an image of the onion skins after I had exhausted them. I used one plastic grocery bag full of purple onion skins.
The resulting dye was a rather fabulous reddish purple. I was hoping to get a nice burgundy or maroon from the dye bath but alas!
Everything was turning yellow! I checked the ph and it was 6.8. That was when I looked up Rebecca's blog. I figured a yellow or army green - as it was coming up at the time- would at least be pretty interesting. However, I forgot about the heat on the oven and went upstairs, got distracted, and came down to a paraboil (it was probably another few minutes from boiling!). Somehow, that activated what little soap I accidentally left in the pot and....
Yeah, lots and lots of soap bubbles! This affected the ph which suddenly shot up to 8.1! I ended up trying to get the dye pot's ph down to see if I could get a good green or red out of it and added 75% vinegar solution to it. It went down to 4.
So I thought with this image, I'd get a neat orange. The dye was completely exhausted when I let it sit through the night. However, when I pulled the yarns out, the linen suddenly didn't have a color and the wools were brown.
