Aluminum acetate is used for mordanting primarily cellulose and bast fibers and it also works as an alternative mordant for wool and silk. We offer instructions for 2 mordant variations: one using tannin and calcium carbonate (chalk) and the other in combination with cellulose scour which helps prepare the fibers for dyeing. You may use percentages from 5-10% on the weight of the fiber. Check out our How to Mordant page which provides detailed information on mordanting.
Please note that Aluminum acetate is very powdery and smells like acetic acid, so a dust mask and good ventilation is recommended when using it.
- 100g of Aluminum Acetate is ample for mordanting 2000 grams (4.4 pounds) of fiber at 5%
