Beetroot stains………everything! It stains chopping boards, fingers, dishcloths and white cotton material a deep crimsony red. So as a natural dyer you’d be forgiven for thinking that you wouldd get that colour if you dyed wool with beetroot. Sorry guys – not gonna happen.
I figured the best way to show this would be to dye some wool with beetroot and share my results.
First thing to do was to get some beetroot, so I headed back to friendly greengrocer and bought some.
All the literature I had read suggested twice the weight of dye material to weight of wool. However I wasn’t feeling overly confident about this project, so I bought 900g beetroots to dye 300g of wool.
I chopped the beetroot up, covered with rain water and boiled for an hour. I use rainwater as it is more natural than the tap water in my area.
Then to extract as much dye as possible, I drained that off, re-covered the beetroot and repeated the process. In the pot the water had turn a wonderful shade of crimson.
In a previous post about mordants, I had commented that some dye materials do not stick to the wool. Beetroot is one of these. So I decided to do a little experiment; dye one hank in the half the dye-bath with un-mordanted wool. It looked so promising, however as soon as I took the wool out of the pot the colour went; I now had a very pale beige colour.
One thing I should point out is that the photographs are not exact replicas of the colours I’ve achieved, but they should give an indication of what happened.
It wasn’t a colour that really appealed to me. Anyway, after boiling for another hour, I got this;
It’s a very pale beige colour. And there you have it; dye extracted from beetroot will not stick to wool that is not mordanted.
But would a mordant make much, if any, difference?
I’d already mordanted some wool and I added that to the dye-bath. Still no vivid red, but at this stage any colour would have been good; this looked more promising.
When I took the wool out of the pot, the colour held. Not the brilliant red one would expect from beetroot, but a soft peachy gold colour.
I left the wool simmering in the pot for an hour. I let the wool cool, then rinsed it through in cool water. When i was finished I had two hanks of peach gold wool. They’re quite a nice colour actually.
As a comparison, this is a photo of the mordanted and unmordanted wool together. The colours in the photo are not as true to life as I’d like them, but I think they give an idea of the colours achieved and the need for a mordant if using beetroot as a dye-stuff.
This was quite fun to do.
As a dye material, beetroot will not give you a vivid red (unfortunately) but it will give a rather nice peach gold colour. Would I use it again – yes!
