Madder and madder

Rubia tinctorum & Rubia cordifolia, Garance de teinturiers et garance ?, indische Krapp u.echte Färberröte , rubia ? y rubia rota, dó madar

Now I really need help with the other languages! Anyone?

I decided to try both “regular” madder and also R. cordifolia (as the latter’s cheaper). I purchased some powdered samples of both varieties and tried them on commercial yarn, mordanted with 10% alum and also with some calcium carbonate added to turn the dyebath alkaline. I couldn’t be sure of this, as the pH paper didn’t change colour, but I added more than the 6g per 100g dyestuff to make sure.madder.jpg

The R. tinctorum is on the left and the cordifolia on the right. From bottom to top it goes thusly: 50% wof, 100% wof, exhaust bath. The cordifolia at full strength gave what I’d call “Indian red” after seeing this tone on so many throws and other items from the sub-continent; the colours in real life are a bit deeper. The top ball was thrown into two exhaust baths, as the dusky pink wasn’t so much to my liking.

With the tinctorum, the full strength gave me what I’d expected, or near enough.

All skeins needed a fair number of rinses to get the particles out of them (it went on the garden); their individual shade was probably twice as dark when coming out of the dyebath, due to the particles sticking to the fibre, but the rinse water was only coloured by the waste particles and no waste/unattached dye.

So, will I use madder again? Not unless I buy a larger quantity from overseas to make it economically viable. When hanging the skeins to dry, the following came to mind: “Avocado skins… avocado pits… Eucalyptus sideroxylon… Eucalyptus cineria…” However, a worthwhile experiment with usable results.

  1. I am growing madder and have some potted up to share if you’d like to grow your own (you do need to take steps to keep it out of your fibre, but surely it is simpler than with powdered dyestuff?) Like you, I am always hoping for a real tomato red and often think when I get deep oranges ” Eucalyptus is simpler and cheaper!”

  2. Mořena barvířská – in czech language. I like to see to dye this color by another dyers. But I don’t like dyeing with it. Red is everywhere. And my striped sweater? The red color was embedded in other colors 😦 Maybe I should use only red. Actually, I prefere the mushrooms red.
