rhubarb is not just for pie

April 8, 2014

after chopping the roots into 1/2 inch cubes they were simmered for an hour and left to soak overnight

the pulp was strained off and the yarn simmered for approximately 1 hour then left to cool overnight

rhubarb can be used as a mordant itself,  but – in this case –  all the yarns were mordanted with alum

the cotton is pale but the yellow/gold on the wool and silk is “knock your socks off” strong


rhubarb is sensitive to pH levels

an after bath made with washing soda with a pH of 9 changed the colour quickly

the skeins were in the bath a quick 5 minutes

P1040742an after bath of iron produced green on the wool and silk

as it can be harsh on both fibres I left the skeins in the water only as long as it took to give a good colour – 2-3 minutes

I put the pulp back in the weak dye bath and will soak for a week then dye again

    How much rhubarb did you use and how much fibre ( approx)? The colours are truly beautiful great job!

      Rosie – sorry I didn’t keep any records. I dug up the root accidentally and used it all and just kept adding skeins to the dye pot until it was exhausted. Not very scientific. It gives a very strong dye bath.

    Rhubarb gives such surprising yellow golds. And it keeps it’s strength, good luck with the second go-round.

      Louisa – yep! you told me so – but it is a little too-o bright for me, it might hit the iron for just a minute.
