Recipe for Preparing a Big Fructose Indigo Vat

Recipe for Preparing a Big Fructose Indigo Vat

Ingredients:

• 300 grams of high-quality indigo powder

• 1 kilogram of sugar (fructose)

• 600 grams of lime (a mix of quick lime and calcium hydrate)

• 120 liters of hot water (at least 70°C)

Equipment:

• Large container or vat (at least 120 liters)

• Two empty pots for mixing ingredients.

• Broomstick

Steps:

1. Prepare the Dry Mixture:

• In an empty pot, mix 300 grams of indigo powder.

• Add 1 kilogram of sugar (fructose). You can divide this into two pots with 500 grams each.

• Add 600 grams of lime, which should be a mix of quick lime and calcium hydrate.

1. Combine and Shake:

• Close the pots and shake well to combine the ingredients into a homogeneous powder. This is your dry vat mixture.

1. Prepare the Vat:

• Fill your large container or vat with hot water (at least 70°C).

• Pour the dry mixture into the hot water.

• Stir the mixture thoroughly using a broomstick or large stirring stick.

1. Dissolution and Waiting:

• Stir well to ensure the powder is fully mixed into the water.

• Allow the mixture to sit and cool overnight. This time is necessary for the indigo to fully dissolve.

1. Testing the Vat:

• After the vat has cooled and sat overnight, test the vat by taking a small sample of the liquid.

• The liquid should turn green when exposed to air and then turn blue upon rinsing, indicating the indigo is properly dissolved and reduced.

1. Readying for Dyeing:

• If needed, add more water to the vat to achieve the desired volume.

• The vat should be ready for dyeing the next day. Ensure the vat is at the right temperature and properly reduced before starting your dyeing process.
