Natural Dyes - Oak Gallnut Extract
Oak Gallnut Extract
Oak Gallnut Extract, a natural extract prepared from Quercus Infectoria Olivier
- 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.
