Using Instant Indigo

Fill a Soup Sized Stainless Steel Pot with WARM water. 90-110 degrees is perfect.

  1. Using a Whisk, stir in half a package (½ oz) Instant Indigo granules.
  2. Sprinkle one heaping Teaspoon of THIOX over the entire surface of water.
  3. Cover the pot & let it rest for 45 minutes to 1 hour.
    This is the when the oxygen leaves the pot, making it usable.
    Maintain a WARM temperature no higher than 110 degrees while actively using the indigo pot.
  4. Remove the lid & submerge your pre-wetted cloth items, yarn, or fiber.
  5. Gently move the items around under the surface, while counting to… let’s say 5 or 15 for starters. Try not to be a splashy duck here, it will introduce oxygen & that’s not a good thing.
  6. While your goods are still under the surface, squeeze out/up the side over the edge into a bowl of cool water. Swish around to remove residue. This is called Water Oxidation & removes any dark “schmutz” from your goods.
  7. Squeeze out & Air Oxidize for 5-15 minutes.
    Air Oxidize simply means hang up the goods & let them rest for a period of time. The idea here is that the more dips & oxidations, the deeper the color saturation will be… with the eventual buildup of color molecules.
  8. Rinse in vinegar water, ¼ cup vinegar to 1 gallon of water.
    Unlike other dyes, Indigo COATS the fibers, hence it will “Crock off,” or shed, if not cured properly or washed enough times to prevent transfer. Curing can take up to 5 washes in mild soapy water.
