Wheat bran is the outer layer (pericarp) of the wheat kernel that is removed when processing wheat grains into white flour. Bran is high in fiber for dietary purposes but provides a different function altogether when used for mordanting. We like to use wheat bran as an afterbath with aluminum acetate as it contains minerals that help enhance the aluminum acetate mordant and brighten dye colors. Complete instructions are in our How to Mordant section.
The amount of wheat bran is 5% on wof, or approximately 1/3 cup per pound of dry goods.
Not recommended for those with wheat gluten sensitivities or allergies. Our gluten-sensitive friends have reported no problems but everyone has a different tolerance level. Calcium carbonate also makes a good aluminum acetate post bath and does not contain gluten. Both wheat bran and calcium carbonate instructions are in our How to Mordant instructions for cellulose fibers.
