Here is Maureen delighted with the colour of her hand spun yarn at the Dyeing the Blues Workshop
The pan below is the Persicaria Tinctoria vat today.
This is both about growing colour quite literally as plants in my garden and also about using them. I dye fibres with natural dyes and use them to "paint" with. This is how I make my landscapes , mostly of the North Wales countryside Mae Tyfu Lliw yn enw addas iawn i'r 'blog' yma. Yr wyf yn cael hwyl yn tyfu bob math o flodau i Helen i'w defnyddio. Mae hi yn creu lluniau bendigedig, mae y lliwiau yn hollol naturiol, ac felly'n gweithio'n dda iawn yn rhoi lliw credadwy o'r wlad o'm cwmpas
I put half of the fibres back for 5 minutes and both went a bit darker.
The dogs got walked at this point so I returned to my two little vats at 5.00pm adding more hot water to the bowl to warm them up, 25ml of washing soda solution* as the pH had dropped to 8 , and 1/8tsp approx of thiourea dioxide.
* Washing soda solution is made by adding 4 tablespoons of washing soda ( sodium carbonate) to 1 litre of water.
I then added back half again of the previous clump of curls. (pH between 8-9 and temp at 38 degrees C) and left for five minutes removed and oxidised. I went on doing this until the fibres really did not look any darker. You can these results below with I.Tintoria (the ordinary Woad) on top and the I. Indigotica (Chinese Woad) on the bottom. There was still colour in both vats so dyed some more fibres a nice light blue photo not shown as the light was going !
