Gall Nuts (powder) 100g – Greys / Browns / Black

Gall nut powder made from oak apples or galls is a rich source of tannins.  It is a substantive dye (does not need a mordant to bind to the fibres in a fabric). When used on its own, achieves shades of cream-grey. After soaking in a dilute solution of ferrous sulphate (Iron mordant), known as saddening, it will produce dark shades of brown to black. Orange can be achieved when Titanium Oxalate is used as the after-soak. It is possible to prepare cellulose fibres and fabric such as cotton and linen, by cycling Tannin with Alum for setting Natural Dye colours. 100g bag
