Madder Dye Cut or ground ~ Dye Colour a variety of reds including orange, browns, reds, brick red, blood red and fiery reds.

*Collected in the Wild of Iran

The colour depends on a variety of conditions, like the soil the roots where grown, their age, the mineral content of the water used for dyeing, the temperature of the dye pot, and how much madder you use in relation to fiber. Many dyers suggest mordanting the wool just with alum and not to use cream of tartar as well, but that is your own choice and why not try to experiment a bit? Like with any dyeing, you will need to soak the fiber overnight or for a few hours before adding them to the dye pot for both hot and cold dyeing. You can dye with madder either cold or with heat; some dyers use chalk or cream of tartar to get better reds.

Colourfastness: Excellent

Also available as dye kit!

Basic recipe:

(You can adjust the amounts as needed)

100 grams dried madder roots (soaked overnight and blended if possible or use ground)
100 grams mordanted (Alum) fiber (50 grams for darker reds or 300 grams for lighter colors)
7 to 10 liters of water
6 grams calcium carbonate (chalk) or cream of tartar, if using

Soak the roots in the dye pot over night
Bring o 65 degrees Celsius for one hour for reds, higher temp. will go more brown
Strain through cloth
Add yarn and dye bag to dye pot
Keep on 65 - 95 degrees Celsius for one hour

**IMPORTANT: The higher the temperature the darker the colour.

Oak Gall - harvested from the wild in Turkey 

Oak Gall, also known as oak apple was and is still used for making ink. We use it as a fibre Mordant, due to its high tannin content. Unlike other tannin, it doesn't stain the fibre.  

Oak Gall is available as whole, cut or ground.

SODA ASH ~ To change colour (PH indicator) and scouring cellulose fibres

No natural Dye Studio can do without Soda Ash. It may be used in small amounts to alter PH or used for scouring cellulose fibres. Soda Ash is alkaline and used to increase the PH in a dye bath as well as in an Indigo Vat. It also brightens yellows, especially Reseda and Sage.

Instructions:

In general Soda Ash can be dissolved in the  hot dye bath at 3-10%. It helps to increase the PH of the bath.

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.

IRON MORDANT ~ Mordant, Colour Changer, increased light fastness

Iron (Ferrous Sulfate) is used alone as a mordant, influencing Colours and to increase light fastness when used in combination with other natural dyes.

Iron is best known for shifting yellows into greens, keep in mind that this is not given and doesn't work with every yellow plant dye, in which case it will be more of a brown. it is used to increase light fastness for weaker plant dyes, bu it will always sadden and/or darken the colours. 

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

Basic recipe:

When adding Iron to your dye bath start of with 3% and use it at the end of your dye bath or as an after bath. Allow to oxidize for 10 min for full colour development.

*If you like your colours darker, increase the Iron amount by 1-2% at a time. 

**Leave for 10min than remove from dye bath - Iron will make wool brittle.
