After a couple dyeing experiments using less conventional dyeplants, I thought it was time to reward myself with something a little more recognised… and to also put a stop to my beheading these wonderfully cheery flowers until I was sure they could deliver a colour that surpassed what I could achieve with garden waste.
According to Jenny Dean in Wild Colour, at least equal weights of flower heads to yarn should yield a cream on unmordanted yarn and a nice vibrant yellow on alum mordanted yarn with more dyestuff creating deeper colours.
A tried and tested dye source I was excited to give this a go.
They steeped for a couple of hours until the water had cooled and then I reheated the water to a low simmer at kept it at that heat for an hour.
I strained off the dye, put the flowers in a bowl and again covered them with boiling water and set them aside, and the returned the dye liquid to the aluminium pot.I then added 1 x 20g skein of mordanted (oxalic acid:chard) yarn and 1 x 20g skein of unmordanted yarn.
I then added 350ml of liquid from the second steeping of the the flowers and brought it to a simmer, simmered for an hour and then left it to cool down and left it overnight.
I again topped up the flowers with a little more boiling water to steep overnight.
The next day I added this extra steeping liquid to the dyebath and brought the pan up to a simmer and simmered it for 2 hours, left it to cool and then left the yarn sitting in the dyebath overnight.
The next day there was still colour in the dyebath but I decided my skeins were taking as much of it as they were going to so rinsed and dried them.
So what do you think, can we call these yellow, or are they really another shade of beige?
Since dyeing these first 2 skeins I mordanted more yarn with rhubarb as the source of oxalic acid and with alum. I had hoped that I had enough left over from my first experiment to try both, but once I’d started with the rhubarb mordanted yarn I decided there wasn’t really enough colour in the dyepot to give the alum a fair shot as well, so that will have to wait for another time.
I have to say I found this a little frustrating. It’s one thing when you’re experimenting with something out of the ordinary but when you’ve been justifying to yourself the picking of heads off lovely bright yellow flowers, because they should yield a truer yellow and you get beige, even goldy beige, it’s a little irksome.
Such was my frustration that I did have a quick try at modifying the colour with acid (vinegar) and alkaline (household ammonia), both very dilute solutions, but if anything they just enhanced the beigenesss…
This is a dyeplant more of you may have dyed with so I’d be interested to hear if I really do need to stick to the alum as a mordant to get a stonger yellow.
See you next week when we go yet further in search of something other than 50 shades of beige…
All the very best ’til next time,
