Aluminum acetate

Used as a MORDANT in natural dyeing, which allows the plant pigments to bond with the fibres.

NOT THE SAME AS ALUM!! Aluminum acetate is used as a one-step mordant on cellulose (plant) fibres such as cotton, linen and well worth experimenting with on rayon fibres (including Tencel), bamboo, ramie, hemp and others. This is a more expensive but faster means to get natural dyes to stick without the more traditional alum/tannic acid premordanting method.

TO USE: weigh dry fibre and scour if needed (especially cotton). Calculate mordant required for 5% WOF (weight of fibre). Weigh and dissolve in hot water. Fill pot with sufficient water for the fibre to move, add mordant and stir. Enter fibre. Bring to 190-200F and hold 1 hour. Stir yarns frequently. Cool overnight, then wash well. Dye immediately or dry for later.

Spent mordant solution may be safely disposed of down the drain (except for septic systems). It also may be diluted and poured on the ground, for instance on a gravel driveway or path.

CAUTION: wear a mask when handling powders. Wear gloves when handling powder or solutions, particularly when rinsing or handling wet yarns. Best done outdoors or with very good ventilation.
