Here is me starting an indigo vat.
3 Gallons of cool water
2 T. Thiox (follow the links)
One 8 oz container will do 10 or more vats
5 T pre-reduced indigo (crystals)
One 2 oz. Container has about 7.5 T
3/4 cup plus 2 T soda ash dissolved in 2 c. hot water
Add soda ash solution and stir in one direction. Slow down and stir in the other direction. Cover with a tight lid. Wait til next post (smile)!!
