Organic natural Indigo ~ Dye colour Blue 

[our Indigo is NOT synthetic]

Country of Origin: India 

The advantage in dyeing with Indigo is, that no mordant is needed.  The water doesn't need to be heated to more than 40 degrees Celsius and a little goes a long way. We can dye 3-4 kg of Wool using 50g of Indigo. 

There are many ways of dyeing with Indigo. Below you will find the recipe for a yeast vat.  For a straight forward no-waiting-required approach, you can use Hydros as an oxygen remover. Waiting time approx. one hour.

Colourfastness: Excellent for dark colours, good for lighter colours

------- 

Basic Recipe ~

It is possible to create a vat from indigo, lime (calcium hydroxide) and over-ripe fruit such as bananas or dates that relies on the chemistry of the sugars* rather than fermentation of the fruit. But it’s easier to simply use fructose shared in

Our Organic Sugar Vat Recipe

Or for a more lightfast solution go for the recipe below or for a quick Vat, use the Hydros Vat, but it does use a chemical oxygen remover.

Our Hydros Vat Recipe

Both recipe are also available as dye Kits

FERMENTATION USING YEAST:

For 500gr wool etc. at one time . (amount can be repeated several times using the same bath)

 9l water

dye container with lid
separate pot for the water bath to add the container
110gr sugar
50gr dried yeast with out preservatives etc.
30gr bicarbonate of soda
40gr ground Indigo
thermometer

This Method requires the dye bath to be on a constant 40 degrees Celsius and shouldn't exceed 50 degrees Celsius. Ideally put the dye pot in a water bath on a wire rack to ensure even distribution of temperature. 

1. Fill pot with 9l of water and heat to 40 degrees Celsius. 

2. Mix sugar and yeast and add to the water. Leave until dissolved and bubbly. 

3. Dissolve soda in a glass with hot water and add the dye, stir until smooth. Add to yeast mixture. 

4. Close lid and ideally put into a bin bag, you want it as air locked as possible. Leave at steady temperature for 8 hours. 

5. Lift lid and stir carefully until all the foamed Indigo has returned into the dye. Try to stir as little air into it as possible.

6. Close the pot up again and leave for 48 hours until the water is yellow green.

7. The water will show a metallic shimmer on the surface when ready. Carefully stir it back in.

8. Add the damp but not mordanted wool etc. make sure all are under the water add a plate or a metallic disc to press the wool etc. under the surface. Whatever swims at the top will be unevenly dyed.

9. Close it up and leave for 6 -12 hours. 

10. Remove wool etc. and press out back into the dye bath.  

11. Open wool etc. and leave exposed for at least 60min. All should turn blue. 

12. If you prefer a deeper blue add it to the dye bath again and repeat step 9. 

13. Wash twice with a mild soap, then rinse 4-5 times using vinegar in the last bath. 

14. Hang up and air for a few days or weeks. 

You can repeat this dyeing process using the same dye bath several times.

PH sensitive, not wash or light fast. Great fun with kids or for hobby dyers. 

For a light purple colour on wool and deep pinks or green, using different mordants. 

*Use 50% of dye according to the weight of the dry fabric/fibre you would like to dye when using ground Hibiscus. 

**Use 75-100% of dye according to the weight of the dry fabric/fibre you would like to dye when using cut or whole Hibiscus. 

Colourfastness: poor
Ph sensitive: purple colour turns green with high Ph

POMEGRANATE PEELS ~ CUT & GROUND ORGANIC ~ can be used as Tannin and as yellow dye

The pomegranate is a fruit-bearing deciduous shrub in the family Lythraceae, subfamily Punicoideae, that grows between 5 and 10 m tall. The pomegranate originated in the region extending from Iran to northern India and has been cultivated since ancient times throughout the Mediterranean region.

 Colourfastness: good - excellent

Recipe:

For how to mordant your Cellulose fibres, please see my blog post 

 How to mordant linen and cotton fabrics successfully – AppleOak FibreWorks

If you are using protein fibres, a simple 10%Alum bath will do for mordanting, but protein fibres can also be dyed without a mordant when using Pomegranate peel due to its tannin content.

Once mordanted:

Add 100% pomegranate peel to 80degrees Celcius Water for one hour. (100% of the dry Weight of your Fibre/Fabric) If using powder, stir regularly or it will burn the bottom of your pan.

After an hour, switch of the heat and add the fabric/fibre. Leave to up to 3 days, until desired depth of colour. 

Wash, rinse, dry.

 Pomegranate Powder can also be used as a tannin and for printing when combined with Alum and Guar Gum.

Organic European Solidago ~ Dye Colour: yellow, orange and green

Our Solidago or Goldenrod in the common tongue, is organically grown and harvested in Europe, Poland.

Solidago, commonly called goldenrod, is a genus of about 100 to 120 species of flowering plants in the aster family, Asteraceae. Most are herbaceous perennial species found in open areas such as meadows, prairies, and savannas. They are mostly native to North America, including Mexico; a few species are native to South America and Eurasia. Some American species have also been introduced into Europe and other parts of the world. (wikipedia)

Colourfastness: medium - good

Basic Recipe for yellow:

100% Solidago
wool (Alum mordant 10%)

Soak the leaves for a day or overnight before using.
Boil the soaked leaves for one hour and drain.

Simmer yarn for up to one hour. Rinse and dry.

Dried Organic Walnut Shells ~ Dye Colour golden and dark Browns

*harvested in the wild in Croatia

Walnut shells or husks are used for plant dyeing Wool and Silk. Preferably, you would like to use green Walnut shells, the dye colour brown is more radiant, but not everybody has a Walnut tree in the back garden, so try the dried shells instead.

IF you do have a tree handy, do collect the green husks and freeze them. You can use them as a dye without any need to fix the colour due to the tannin content.

If you use the dried husks, I would suggest to use a mordant, too. But do try without it, you might like the result!

Colourfastness: Good - Excellent

---------------

Basic recipe:

100% of Walnut shells
Wool (Mordant not necessary)

Soak the shells overnight
Simmer for 2 hours
Strain through cloth.

Add wool to the dye bath simmer for one hour.
Let it cool and leave in dye bath overnight.

Rinse and dry.
