Jacquard Soda Ash Dye Fixer, 1lb
Soda Ash, also known as sodium carbonate, washing soda, or sal soda, is a mild alkali that promotes chemical reactions between fibers and dyes such as indigo or Jacquard's Procion MX line. The ash is necessary to activate and "set" dye to its targeted fabric. Daniel Smith offers this fine product in 1 lb. packages.
