Natural Dyes - Oak Gallnut Extract

Oak Gallnut Extract Oak Gallnut Extract, a natural extract prepared from Quercus Infectoria Olivier or the Aleppo Oak. Any fiber can be dyed with oak gallnuts. It is used to increase lightfastness. Oak Gallnut can be used to create dark shades with madder or indigo on wool and silk with minimal use of iron sulfate. This gallnut extract was specially developed for textile and natural dyeing uses and has a very high content in tannic acid combined with low color.  The tannic acid is perfect for the pre-treatment of cellulosic vegetable fibers (named engallage in this case) to improve the fixation of the mordant during the mordanting step. The oak galls are produced by the tree as a defense against the sting of an insect in buds. The tree excretes a tannin-rich substance that becomes hard and forms a gallnut. Gall Oaks are present around the Mediterranean Sea and in Minor Asia.  Instructions for use included! Be sure to check out our Mordants and Assists
