We are Oak Gall (Quercus Infectoria, Aleppo Oak Gall) producer from Turkey since 1950. Our gallnut is green and brownish-white; both are very rich in tannin, approx. 65–70% tannin. Buy wholesale oak gallnuts from Turkey, themazi company.
Oak Gall is a natural/organic tannin that is used in fiber dyeing, Cosmetic and Medical purposes. It's also used to make Wine.
We produce and store nearly 500 tonnes every year. But if needed, we can increase our capacity. We are able to supply in different forms; whole, broken, and powder.
Gallnuts from the oak tree are the earliest and richest source for natural tannin. They are produced by insects who deposit their eggs in small punctures they make on young branches. As a protection, the tree excretes a tannin-rich substance that hardens and forms into a gallnut. These are collected and ground for use as a tannin mordant.
Gallnut or Oak Gall is used to mordant lose fibers and fabrics before the alum mordant is used. Alum does not combine as readily with lose fibers as it does with protein fibers.
Tannin has a great affinity with lose fiber and once mordanted with tannin, alum combines well with the tannin-fiber complex.
Oak Gallnuts is abnormal outgrowths of plant tissues caused by various parasites, particularly insects. Oak galls, found on oaks in the Middle East, have long been used to make high-quality ink and for dyeing.
The tannic acid is perfect for the pre-treatment of losic vegetable fibers to enhance the fixation of the mordant during the mordanting fiber.
Any fiber can be dyed with oak gallnuts. It does increase the lightfastness of the resulting colors. In the presence of iron sulfate, oak gall forms very solid and very dark complexes.
