I was checking back on some old posts and was amazed how much I wrote in 2007 and feel somewhat abashed at the contrast with now. I am dyeing most of the time and making inks ( which are selling very well) but don't think to blog about what has become routine(ish).
Kev, a fellow member of the members of the Online guild of Weavers Spinners and Dyers, sent me some of his own weld extract which he had made himself, I am not sure when but probably about 18 months ago.
Here is his website with the information on how to do it. A couple of weeks getting ready for a couple of big workshops I needed some greens in a bit of hurry and realised I had still got Kev's extract. You know what it is like when someone sends you something a bit special you put it on one side to use for something special. Then, months later, when you are tidying up you find it again. So this time I thought I will use it instead of waiting for this mythical special event!
He had sent me a small pot of the weld extract- but did I weigh it -did I heck :( . I tipped the small hard dull yellowy brown pieces ( probably about 20g or so) into a small jug and poured over hot water. If I had checked Kev's website I would have seen he said to dissolve it in ammonia but dissolving it in hot water worked well although it took half an hour or so. I poured the resulting liquid into a slow cooker, topped up with water and added 200g of merino tops mordanted in 8%alum 7%cream of tartar. See
here for more about mordanting .
The fibres came out a bright yellow but I added a drop of ammonia-if I do not when the wool used in felting the fibres go a bright floresecent yellow with the pH of the soap.
rinsed the fibres, partially dried them and then
immersed into an indigo vat . Look at the absolutely gorgeous green in the top right of the top photo.
Altogether the weld extract dyed 600g of merino tops in strong to pale yellow and overdyed with indigo I got some yummy greens .
Thank you Kev - this was infinitely better than attacking my pile of dried weld which needs to be chopped up outside as it make such a mess.
