more from the haphazard dyepot

Experimenting with the theory that an aluminium pot can act as a mordant. Same sad old (formerly) white cotton top as before.

 Once again, lacked time and patience to pre-soak or really follow the instructions in the lovely book, like soaking overnight in aluminium-pot-water.

 Dumped loads of coffee grounds in with cotton top and water and brought to the boil for half an hour or so. Partway through, thought hey, maybe I have a source of iron-as-mordant too.

 Who knows? Worth a shot. Normally used in the garden on things like my yellowish macadamia tree.

So yeah, cooked it up for a while, let it sit for a bit. It looked to be going a fair bit darker than the first time. Then I went to rinse it out. Which is where I found...

 Our source of mordant-rich water! Yes, the rusty old rainwater tap in the laundry. The orange-tinted water that comes through the rusty pipe is exactly what was called for! I could actually see colour processes happening as I rinsed: the rust-coloured water became quite a dark grey.

 I will spare you any further gruesome underarm shots - suffice to say that the aluminium content is still working away and the top is no more wearable than before.

 But what a cool experiment!

Um, here's our pretty cat Elodie, and some weeds. Happy Thursday.

if it's worth doing, it's worth doing half-arsed and learning from the process

In Sydney, I was super-excited to go to the awesome bookshop Kinokuniya. I would have spent hours there poring over their selection of Japanese pattern books and crafty booky goodness, only I had the three kids with me and they had chosen their books and were not at all interested in mine.

I did however manage to hastily select this beautiful book, and get all excited about dyeing my own fabrics using plants.

When I have a new crafty notion, I want to jump straight in. Make do. Make it up. Whatever.
Dyeing with coffee sounded like an excellent place to start. We make heaps of coffee grounds at home, and apparently because coffee contains tannins, these act as a natural 'mordant' i.e. binder of colour to fibre. I had an old white top that would do for an experiment.
I didn't soak the fabric for an hour or more like you're supposed to. Too impatient.

Just plunged it into a saucepan with cold water and a heap of old coffee grounds, and gradually heated to a simmer. Simmered for 20 minutes then left to steep for about an hour. Wrung it out and rinsed it well.

The mordants that I speak of? One recommended is alum, or aluminium sulphate.
Deodorant? Full of aluminium.
Old white top? Full of deodorant.

eww! I post this, you understand, in the interests of better crafting

In fact I grabbed it out of my drawer, where (gulp) it might have gone back after a light wear and not even been freshly washed.

yep, that's probably even deodorant that got onto the bottom when I pulled it over my head

Poor old white top. On the upside, it certainly demonstrates the effectiveness of using a mordant.
Live and learn.
(Am excited about possibilities of dyeing with red cabbage though, and looking forward to trying with some untainted, fresh, soaked fabric!)
