It's the ammonia/yeast vat that I am going to make and this is how I am going to do it:
- add 5 tablespoon of powdered Yeast and 5 rounded tablespoons of Sugar to 5 cups (200ml) warm water and leave for 2 hours.
- at the same time dissolve 5 level teaspoons of Indigo to 2 and 1/2 cups (500mls) Ammonia.
- After the 2 hours add the indigo and ammonia to the yeast-sugar mix in a large container and fill to about the 2 1/2 gallon mark. Cover with plastic wrap and use a rubber band to seal. (The fermentation can burst a rigid seal.)
- Leave to sit for several days in a warm place.
