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.

The yarn going into the dye pot. How pretty is that.

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.

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.

My dried and wound up gardenia dyed yarn.

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.

Natural dye experiments- onion skin + iron = green

I've been interested in natural dyes for a while now; I read a lot of blogs and endlessly wonder what colour I could get from plants I pass on a daily basis, but this is the first time I have systematically experimented with them.
After reading about how easy it is to make natural mordants at home and how they can give different colours to dyes, I decided to take the plunge.

First I needed a dye journal (of course) to record all my recipes in so I could repeat a colour if I wanted to.

My new dye journal.

I had a refillable cover made already (see this post for how I did it) so I whipped up some saddle stitch signatures to fill it with and away I go.

Measuring the holes out very precisely (sort of) with another signature.

Punching holes so I can stitch the pages together.

 Natural dyeing is a huge subject, so I won't try to explain it all in one post. The basics are simple though; natural fibres such as sheep wool, alpaca, cotton and silk can all be dyed using plant and animal products. The general method is to boil stuff and soak fibre in the resulting liquid. Most dyes obtained from plants need a mordant (which helps the colour stick to the fibre), mordants are usually salts or metals such as alum, iron, copper, salt and vinegar, so I read up on how to make some at home and had a shot at it.

 I made iron and copper mordant by filling two old jars with water and a half cup of vinegar then throwing (well placing carefully) copper pipe in one and iron in the other. I left both jars on a shelf and used the iron mordant with great results two weeks later.

The one on your left is iron and the one on the left is copper.

Of course I wrote it all down in my dye journal.

 Having read that onion skins (usually a yellow dye) with iron mordant can give greens I just had to try it. So I broke out my supply of saved onion skins and boiled up a batch of dye; just throw onion skins in a pot of water and boil away (be aware that your partner or children may erroneously believe you are cooking dinner as it smells like soup). Meanwhile I poured two cups of iron mordant into a big pot of water, added 50g of washed merino wool and put it on to heat. When the mordant pot came to the boil I turned off the heat and let it sit for an hour. After that I strained the onion skins out of the dye pot and dumped the liquid dye into the mordant pot. The fibre immediately began to go a dark greenish brown, so I just let it sit.

The colour started to go into the wool straight away, so exciting.

 After a couple of hours (while I was forced to study and do house work) I fished the wool out of the dye vat and took it outside to dry. There was still a fair amount of colour in the pot so I just threw in another 50g of merino to see what colour I would get with no mordant except what was left in the mix.

I'm fairly happy with the result.

Hope it keeps it's colour as it dries.

It's the same colour as Barry's wing feathers.

I dutifully wrote it all down for later perusal.

 The colour is so deep; maybe because it's natural dye it has the same look as Barry's wing feathers, they sort of glow with colour. I hope my wool keeps it's colour as it dries and I can spin up some beautiful green yarn to make a hat or something.

Next I'll look for a recipe that uses copper mordant and makes purples or blues.
Any suggestions?
