They are an essential ingredient in making oak gall ink and can also be combined with iron to produce gray, purple and black shades on textile fibers. Our oak galls are often referred to as Aleppo Oak galls as they come from the Aleppo oak tree (Quercus infectoria). The tree is native to Southern Europe, Turkey, Syria, Iran, Iraq, Cyprus, Lebanon and Israel. The gall is formed when an oak leaf bud or large leaf vein from the Quercus infectoria oak is invaded by the gall wasp and the wasp lays eggs in the twig. The wasp larva exudes a chemical that creates a protective housing (the gall) on the twig so it can feed and undergo metamorphosis into adulthood. The adult wasp exits the gall leaving behind a tannin-rich ball. Use oak galls at 10-50% weight of fiber. Alone, oak galls make a light beige color and lighten slightly when followed by an alum mordant. When dipped in an iron afterbath, the color quickly changes to a gray or “black” shade. The ground oak galls have been crushed and sifted and may be strained and reused. For more detailed instructions, please see our how to page. Ground oak galls are available in 100, 250 and 500 gram bags. Oak galls come in various sizes and may be small and hard inside or larger and spongy.
