This blog is about dyeing with plants and mushrooms.
Tässä viime viikolla intialaisella indigolla värjäämiäni lankoja, kaikki on värjätty harmaalle langalle, keskimmäinen 1715 on yhdistelmä pietaryrtillä värjätystä vaalean keltaisesta ja indigolla värjätystä sinisestä eli väristä tuli hiukan turkoosi. Mitään näistä ei ole isoja määriä, eniten tuli tumman sinistä 1712, 900g. Seuraavia värejä 1713 ja 1717 tuli molempia 600g, vaaleinta harmaan sinistä 1714 500g ja turkoosia 300g.

Here are blue yarns I dyed last week with indian indigo. All are dyed on grey yarn, the one in the middle 1715 was dyed first pale yellow with tansy and then blue with indigo.
I don't have very much of these colors, darkest blue 1712 I have 900grams, middle blue colors 1713 and 1717 I have both 600grams. The lightest blue 1714 I have 500grams and no1715 300grams.
Today I dyed with dry rhubarb roots, that had soaked for two days and were boiled yesterday for about 2 hours. I had 180grams of dry roots. I divided the strained bath to two parts, to the first I put two 50gram skeins of white alum mordanted yarn. I let them simmer for a little over an hour and then they looked like the left skein in the top picture, gold yellow. To the after bath I put 100grams of white alum mordanted yarn and after two hours it was the skein on the right in the top picture, quite pale yellow. The pH in this bath was about 6.
I then added to the bath 9grams of washing soda and the pH was now 9. I put another of the gold 50gram skeins from the first bath to it and let it be for 10 minutes. Its color changed from gold to orangey peach, the one on the left in the bottom picture. I meant to let it dry in sun, but today was cloudy, hopefully tomorrow sun shines. I haven't washed that skein yet, I want to see what happens to it in sunshine.
To the second half of the divided dyebath I put also 100 grams of white yarn, this time unmordanted. It soaked up color really good, after an hour it looked like the skein in the middle in the top picture. A little greenish yellow compared to the gold yellow with alum mordant. I took the skein away from the bath just to take that picture, I then added 1gram of iron (ferrous sulfate) to the bath and put the skein back for another 15 minutes. Now it had changed to the green, the one in the middle in the bottom picture. Nice color, hmm, it looks like more of the ones you get with copper mordant rather than with iron.
So the yarns what I ended up are all in the bottom picture, from left to right: first the alum mordanted with washing soda, then alum mordanted, then iron mordanted and last the alum mordanted afterbath.
I had 180grams of dried roots and got 200grams of first color and 100grams from afterbath. Dean says that you can get orange from these, maybe with more roots/yarn I can imagine that would happen.
I am very pleased with the gold yellow I got with these roots, according to Dean, this should be lightfast color, but I will put them to test. I am a little sceptical about that peach color but we'll see. I will write later what happened. You can get the same gold yellows with onion skins, but I think they are not lightfast enough for me to sell, I am hoping these are. Now I know, I will have to dig some of my own rhubarb roots up in September to get more of roots to dye with.
I wonder if you get the same colors with himalayan rhubarb roots?
I started thinking if storing the roots longer would affect the color, these were dug up and dried in last spring? I have read that with tree barks, especially glossy buckthorn, which contains same emodin than rhubarb roots, you can get more color if the bark is stored at least six months. Something happens to the bark during storage, maybe it is something to do with enzymes??
Oh, and the smell doesn't feel so good anymore after longer time, not very bad either. It stays a little with the yarn at least for now.
