SODA ASH ~ To change colour (PH indicator) and scouring cellulose fibres

No natural Dye Studio can do without Soda Ash. It may be used in small amounts to alter PH or used for scouring cellulose fibres. Soda Ash is alkaline and used to increase the PH in a dye bath as well as in an Indigo Vat.


In general Soda Ash can be dissolved in the  hot dye bath. It helps to increase the PH of the bath.
