In all of the natural dyeing I’ve been doing (or hoping to do!) in the last little while, I read a little about using wood ash as a dye modifier. In Rebecca Burgess’ Harvesting Colour: How to find plants and make natural dyes, she notes that wood ash can be used interchangeably with soda ash to create an alkali after bath. In reading about fermentation dyeing, wood ash lye also came up, and further it came up in my experiment with my first woad harvest.
Rhubarb leaf mordant
Along with chemical mordants like aluminum, copper, and iron, Jenny Dean also notes the use of staghorn sumac leaves, and oak galls as possible sources of natural mordants in Wild Colour: The complete guide to making and using natural dyes. These are rich in tannin she notes, which helps colour adhere and increases light and wash-fastness on vegetable fibres.
However, since I am LOVING spinning wool (and didnt’ love spinning hemp or flax that much in comparison) I really was interested to read about her recommendation for protein fibers – rhubarb leaves. Continue reading
Iron as a pre-mordant
In all of the natural dyeing I’ve been doing (or hoping to do!) in the last little while, I read a little about using iron as a pre-mordant instead of alum. In Rebecca Burgess’ Harvesting Colour: How to find plants and make natural dyes, she notes that while alum is used for most of recipes in her book, iron is useful in several.
I’ve read about oak galls and their place in dyeing and ink-making a little, and didn’t think too much of them – I don’t really think of oak trees in Calgary (compared to trips to Louisiana!) but while out for a walk (playing PokemonGo!) I noticed that one of the parks near me had cute little (young) oak trees. A closer look… and there were the weird clustered balls.
If you’ve read my blog for a while you’ll know that I am really enjoying exploring natural dyes. I don’t suspect I’ll ever be as prolific or dive in as deep as others I know, but I’m having fun at the moment.
As part of that, I like the idea of using found-dyestuffs; things from my garden or wanderings, or in this case, my kitchen. While lots of natural dyestuffs are available by order, these found-dyestuffs appeal to me – for lots of reasons, including economy! Continue reading
