Soda ash (SA), also known as 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 raise the pH of an indigo vat or scour silk fibers.
