Natural dye experiments - gardenia powder and alum

My natural dye experiments have continued into the garden; I recently tried gardenia powder to dye some 100% wool yarn, and the results were spectacular. I found a listing for gardenia powder in my favourite dye stuffs shop (for the bits I can't make myself); KraftKolour, and having a few dollars to spend (thanks to selling some home spun cotton yarn) I bought it. I was really curious to see what sort of colour I could get from a common garden plant. My mother recently found a mixed bag of pure wool in a second hand shop in white which she gave to me (thanks Mum), so I had a decent amount of yarn to play with.

The process is really very simple; weigh your fibre; mine was 123g, gather your equipment and off you go.

The yarn my mum found in a second hand shop.

I decided to mordant my yarn with alum at a rate of 15g per 100g of yarn (and yes I did use a calculator to do the maths).

I weighed up my alum and popped it into my yard dyeing pot with some water.

Once I had the alum mixed in fairly well with the water in my dye pot I plonked in the yarn in handy skeins (all tied up with cotton yarn so I didn't end up with a tangled mess). I bought this pot to a simmer then turned it off and let it sit while I made up the dye.

My dye was mixed at a rate of 6g per 100g of yarn (yes...calculator again) in a big stainless steel pot. The dye comes as a sort of bluish powder but the dye pot goes a dark blue colour. I heated this water up almost to a simmer (close enough to the same temperature as the yarn in the mordant).

Then I fished out my skeins (using my trusty serving fork, that is only used for fibre work) and lowered them into the dye pot.

After about ten minutes it was this colour.

I turned off the heat on the dye pot and let the yarn sit until it was completely cool. Actually it sat in the dye until I remembered what was in the big pot on the bench while I was washing up that evening.
Then I rinsed the yarn in cool water, wrung it out and whacked it against a post to separate any felted strands (force of habit) and hung the skeins up to dry.

Drying skeins

As you can see the different brands of yarn took the dye up at varying rates. I love the different shades though and they are all very pretty.

I am so impressed with this colour I think I will get spinning and make some merino home spun to try it out on; maybe I can get enough of a single shade to make a jumper or something.
