Remember this jar on the right?
It was eventually done cooking on the stove. 2 days like the other 3 skeins, ph 2, as high as I managed to get it. Pure vinegar with some acetic acid. I measured again when done and it was closer to 1.
I was very excited to see if it would keep its rose tint during the dye process and of course after. Well, here you go:
Unfortunately it seems that rinsing out the vinegar will push it towards purple once it dries. Even if there is actually a bit of vinegar in the 2nd rinse water. OR it could be heat. See, I wanted to wrap up this post and put the yarn close to the stove. The most wet ends turned more purplish than the rest before I noticed and moved it. Sic! So, heat definitely pushes it towards purple. As well as time.
I meant to do another skein in there upping the ph slightly – but I lost steam, didn’t get to mordant more yarn, and, well.
I’m going to re-photograph all the skeins later, as they do seem to change a bit after curing. I also don’t always rinse them until they’ve dried and rested for a bit.

Dre asked me about pH change during the process. I did not measure at each temperature shift, but the juice in the above photos, which started out at 8 and 2, are now 6 and 1 (or that’s as low as my strip goes). The two jars in the window however have not changed since I made them, they’ve been in temps between 15-20 C.
Just for fun I think I’ll stuff some fleece in the highly acidic jar, then afterwards dip it in the former alkaline jar. Which is now no longer alkaline, where did that ammonia go?!
Fun fact which unfortunately I wasn’t allowed to document: when I hung the pink skein to drip in the shower (white floor), the splash pattern was pink in the middle with a larger ring of drops around it, they were indigo blue! As well as the run off between the tiles, dark, dark blue.
Anyone care to take a guess at what happened there and is it related to the pink/purple issue of the finished skein?
