Aluminium acetate mordant is a very fine white powder used to fix (mordant) natural dyes (except indigo & woad) to natural fibres. It is our preferred mordant for cellulose (plant) fibres, being easy to use and reliable.
With aluminium acetate mordanting is a one-step process. There is no need to ‘double mordant with alum-tannin’. Can be used for both hot and cold mordanting.
Like alum, it is refined from bauxite.
We recommend using at 5g per 100g dry weight of fibre.
