The bark of Acacia Mearnsii (black wattle) contains significant amounts of water-soluble components called "wattle tannin". This extract is the concentrated form of wattle tannin of the catechic tannin group. To this group also belong; Cutch, Quebracho, and Tea leaves.
Acacia tannin natural dye extract dyes a reddish brown but will turn deep slate greys and blacks with a post mordant of 1-2% Ferrous sulfate.
Use at 5-20% WOF, acacia tannin extract dissolves easily in water without a need to make a paste prior to dyeing.
