Oak Gall Powder (Green) is a tannin-rich natural material used in natural dyeing—especially to pre-treat cotton and linen before mordanting and dyeing. A tannin bath helps dyes and mordants bond more effectively, improving depth, clarity, and consistency of color.
Best for: cotton & linen (cellulose fibers), eco printing, botanical dyeing, and iron–tannin processes.
Botanical name:Quercus infectoria (Aleppo oak)
Origin: Turkey (Mesopotamia region)
Quick use
