mordanting

My knowledge of natural dyes and chemicals involved in mordanting enabled me to create coloured photographic emulsions.

Carol continues " Alternatively, we could do a more complex workshop and do all the preparation of the wool on site plus the mordanting, and then the dyeing".

To mordant the prepared fibres mix 250gm of alum and 25 gm of soda ash (anhydrous sodium carbonate) in 5 litres of hot water and allow to soak for up to 24 hours, rinse in warm water and dry and then repeat the mordanting.
