Ammonium Sulfate is an acid forming salt that can be used with Wash Fast Acid Dyes. The best choice of “acid" when level dyeing is important because at room temperature it is a sal t and as it is heated it forms an acid (begins to release acid at about 150 F). Please note: Products are filled by weight, not volume. Due to plastic shortages, jars, lids and bags may vary. Show more
