Tannic acid

Used mainly on as a MORDANT on cellulose fibres such as cotton, usually in combination with Alum.

TO USE: weigh dry fibre. Calculate mordant required at 15% WOF (weight of fibre) each of Tannic Acid and Alum. Weigh mordants and dissolve in hot water in separate plastic or non-reactive containers. Add wetted fibre to Alum solution and soak for 12 to 24 hours. Rinse and place in Tannic Acid solution for 12 to 24 hours. Rinse again and place back in Alum solution for 12 to 24 hours. Wash and rinse well, then dye or dry for later use.

Spent mordant solution may be safely disposed of down the drain (except for septic systems). It also may be poured around garden plants that prefer acidic soil conditions.

CAUTION: wear a mask when handling powders. Wear gloves when using tannic acid, particularly when rinsing or handling wet yarns as it can cause skin burns or irritation.
