Description
Ammonium sulfate is a mild acid forming salt which can be substituted for vinegar or citric acid. Its great advantage is that it forms acid slowly, starting from a neutral ph when first dissolved in room temperature water, and releasing more acid as the dye bath is heated to around 150°F. The gradual release of acid promotes more level colors than citric acid produces; that is, smoother, more perfectly solid colors, as opposed to mottled colors.
