When working with indigo first pre-wash the goods you would like to dye, also known as scouring, to remove any excess dirt, wax, or starch. Unlike other natural dyes, goods you plan to indigo dye do not need to be mordanted.
To learn how to use scour, and to learn how to create an indigo vat, with very detailed instructions, pick up a copy of our book, .
In order to create indigo-dyed cloth, the indigo must be made water-soluble. In order to accomplish this, two things must take place to prepare the indigo vat for dyeing.
1. The vat must be a pH of 10-11
(find pH strips in the drop down menu below to measure the pH)
These are ingredients which raise the pH of the indigo vat:
- lye
- soda ash
- limestone
2. All of the oxygen must be taken out of the indigo vat (known as the reduction process).
These are ingredients which aid in the reduction process:
- sodium hydrosulphite
- henna
- iron (ferrous sulfate)
The Modern Natural Dyer recipe requires:
20g indigo
50g lye (sodium hydroxide)
50g sodium hydrosulphite
** this recipe will dye approximately 500g (17oz) of goods a medium to dark shade.
-- OR --
50g indigo
100g henna
100g limestone (calcium hydroxide)
** this recipe will dye approximately 250g (8oz) of goods a medium to dark shade.
***CAUTION***
You must use proper precautions when working with lye.
Please read before proceeding.
- Always wear gloves and protective eyewear.
- Do not let lye touch your skin, as it is caustic and can burn. If lye touches your skin, rinse immediately.
- Only add lye to water; never add water to lye.
- Use only cool water when working with lye.
- Never add lye to boiling water, It can explode.
