Soda Ash is used with the Cotton Dyes, to create an alkaline environment for the dye to set.
The material or yarn to be dyed is soaked in the Soda Ash soloution before applying the dye.

Soda Ash is an alkali and can cause skin irritation, and shouldn't be inhaled, so please use gloves and a dust mask when using it, and wash off any spills with water.

To mix, fill the bucket or container with warm water first, and then add the Soda Ash and mix well.

Approximately 1 cup of Soda Ash to 4 litres of warm water.
