Soda Ash
Base Unit 250g
 
Soda Ash or sodium carbonate, is a workhorse in the dye studio. It is an easy way to add alkalinity to a dyebath to modify its shade. For example, when added to a madder dye bath, soda ash will cause it to redden. It is also an easy way to increase the pH of an indigo vat or to scour silk fibres.
