Make your project a success with aluminum sulfate. Alum is used with some natural dyes as a mordant. Especially for Bengala dyeing on wool, it prevent felting by skipping the extra steps of rinsing and kneading in the pre-fixer process. Alum water works like pre-fixer to help the color stick to the wool fabric or yarn more easily.
Also it is a powdered presoak used to treat fabric or for marbling. It ensures that designs transfer clearly to fabric or paper surfaces. This package contains one pound of aluminum sulfate. Made in USA.
