About our pure natural woad extract

Our pure, natural woad powdered extract is sourced in Europe and produces beautiful blue shades. Like indigo, woad requires a ‘vat’ method and we have all the additional ingredients you may need for a successful vat.

What are natural dye extracts?

Our powdered natural dye extracts are made from 100% natural ingredients. They are highly concentrated powders and can be used like any natural dyestuff.Think of them as being like dried herbs compared to fresh ones!

The extracts are sustainably sourced and fairly traded from responsible suppliers. Concentrating the extracts reduces the carbon footprint of transportation. Many of the extracts are GOTs certified and information can be provided on request.

What can I use natural dye extracts for?

Most extracts can be used for all types of dyeing: Immersion, semi-solid, handpainting, tie-dye. Thickening the dyes with gum tragacanth or manutex allows them to be used for more precision painting techniques. They can be used on any natural fibre including wool, alpaca, silk, hemp, cotton, linen and on fibre blends that are predominantly natural . They will dye yarn, fleece, fabric etc. (With indigo and woad, some techniques such as handpainting require different processes)

How do I use them?

Indigo and woad are not mordanted with alum (but see the note on overdyeing below). These dyes require a ‘vat’ method. There are many different types of ‘vat’ and if you already have a preferred method, our extracts should work for you. If you are using indigo or woad for the first time or need a refresher, details of a simple method can be found in the downloadable free leaflet on our product guides page. We also supply kits for indigo dyeing as well as the additional items required for preparing and using an indigo/woad vat.

Extending the colour range with colour ‘modifiers’

Natural dyes (including indigo and woad) can also be ‘modified’ with additional products, allowing a range of colours to be achieved with just one extract. Try citric acid, sodium carbonate, copper sulphate or iron (ferrous) sulphate for different results.

In the images as shown, the following modifiers have been used:

1: Indigo and woad dyed in a standard thiourea (‘thiox’) vat (no alum) – see above and our product guide for more info)

2: Vat dye + Citric acid

3: Vat dye + Sodium carbonate

4: Vat dye + Ferrous (iron) sulphate

5: Vat dye + Copper sulphate

All our extracts are supplied in re-usable plastic pots making them convenient to use and store. A simple instruction leaflet can be downloaded free of charge from our product guide page. For a more comprehensive introduction, we also have a range of inspiring kits to start you on your natural dyeing adventures!
