I woke up early this morning, ran out to the dyepots, and rinsed out my samples!
From left to right, they are varying grades of violet to turquoise @ 4% DOS, and then the first few stages of violet-to-magenta, also at 4%.
Because the dyebath did not exhaust completely, I decided that I must have used too much dye, so for the next batch I reduced the dye to 2%. It came out considerably lighter, but the dyebath still did not exhaust.
Puzzled, I revisited my calculations, and realized I’d put in roughly THIRTY times as much leveling agent as I should have! I had been putting in 8 ml where I should have put in .4 ml. That’s what comes of being a math major!
(At Caltech we had a rule that said the youngest non-math major had to calculate the bill whenever we went to a restaurant. The youngest got stuck with the chore, but it was generally agreed that (theoretical) math majors were so hopelessly incompetent at arithmetic that they should be exempted. And I was a math major! That’s my story, and I’m sticking to it. 😉 )
And here is a photo of my dye sampling setup:
It’s basically an electric frying pan with a bunch of canning jars in it. Watch this space, though, because I’m going to upgrade it! I got so frustrated with the canning jars (which are way too big for my 40 ml dye samples) that I ordered an entire case of 60ml Pyrex glass vials from eBay. They are way smaller than the pint jars (a pint jar is 450 ml!) so I should be able to do larger sample batches using the smaller vials. Assuming the whole idea works. I guess I’ll just have to try it!
I know there are people out there who find dyeing samples (or weaving them!) to be incredibly tedious, but I find it absolutely fascinating. You can find out so much in such a short time! And it’s magical to see the results coming in after just an hour or two. After spending an entire year on the dress, I think I’m entitled to some instant gratification!

Lovely idea! Do you simply put water in the pan at a certain temperature and let the jars cook? I love dyeing and am looking forward to doing some more of it this summer. How well do you like your setup?

Tien, you must admit that you have farmed the tedious aspects out to others…………! You have good friends indeed!
