SODA/SODIUM CARBONATE FOR INDIGO

Soda Ash/Sodium carbonate is slightly alkaline and is needed for the indigo vat. 
To dye with indigo you need sodium carbonate in addition to sodium hydrosulphite. 
It is added later to the vat (content of the dye bucket).  
Sodium carbonate is meant for use with the pre-reduced Jacquard Indigo dye. 

1 part of pre-reduced Indigo Dye & 2 parts of Sodium Hydrosulphite & 4 parts of Sodium Carbonate/Soda Ash (use 4 liters of water per 20g of dye).

Wishing you much success dyeing!
