no.1 Sodium Carbonate

Scouring agent
500g (17.6 oz) Sodium Carbonate

Sodium carbonate, also known as washing soda or soda ash, is a versatile and essential ingredient in the scouring and mordanting process of cotton for natural dyeing. It helps to raise the pH of the fibers and remove any impurities, making them more receptive to accepting dye. It can also act as a mild mordant on its own or in combination with other mordants. The use of sodium carbonate is common in eco-friendly dyeing practices as it is non-toxic and readily available.

No worries, if you need further instructions, Our Cotton Mordanting Kit includes all the necessary instructions and materials for scouring and mordanting cotton using sodium carbonate. Available in our shop.
