Organic natural Indigo ~ Dye colour Blue
[our Indigo is NOT synthetic but the real stuff]
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.
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
Michel Garcia’s 1-2-3 recipe. It’s very simple: One Part indigo,two parts lime and three parts fructose, plus warmth.
*Fructose and glucose found in ripe fruit are reducing sugars; ordinary sugar – sucrose – is not a reducing sugar.
FERMENTATION USING YEAST:
For 500gr wool etc. at one time . (amount can be repeated several times using the same bath)
dye container with lid
separate pot for the water bath to add the container
50gr dried yeast with out preservatives etc.
30gr bicarbonate of soda
40gr ground Indigo
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.
You can repeat this dyeing process using the same dye bath several times.
LOGWOOD ~ Available Cut or ground and as extract*
(Bois de Campeche, Campeachy Wood)
*Collected in the Wild (foraged) in Haiti
Logwood is a natural dye wood from Central America, used for producing blues and purples on wool, black on cotton and wool, and black and violet on silk.
Logwood is PH sensitive.
It is called by old dyers one of the Lesser Dyes because the colour was said to lose all its brightness when exposed to the air.
65g bark, soaked in water for 2 days.
100g mordanted yarn/fibre (Alum 10g)
Bring pot with dye to simmer For 2h.
Strain through cloth, add yarn/fibre and dye bag to dye bath for 1h.
The logwood chips should be put in a bag and boiled for 20 minutes to 1/2 an hour, just before using or soak overnight, bring to the boil in the morning for 1h, strain and bind into bag.
* When using extract you only need to use 5-10% of the weight of your dry fabric. Logwood is one of the more excessive dyes - a little goes a long way - especially when using extract.
Black Beans or Black Turtle Beans ~ known generally to the cooking world, this bean makes a wonderful food dye. Not necessarily very colourfast, it matures into a beautiful ceramic colour - silver grey with a touch of blue. Because you are only using the soaking water, you can use the beans for cooking afterwards, making it a very 'no waste' food dye.
100% Dried Black Beans
100g Cream of Tartar
After you have soaked the beans in cold water overnight - remember we want the soaking liquid so don't drain it away!
Fill a big pot with fresh water
Stir the beans to extract as much colour as possible.
Take a sieve and drain the liquid into the pot.
Put the beans back into the pot and fill with water again, stir than drain into pot.
add 100g of Cream of tartar to the dyebath.
add the table cloth bring to 80 degrees for 1 hour.
Leave overnight or 12 hours.
Rinse and dry.
