Item details

Oak Gallnut Extract, a natural extract prepared from Quercus Infectoria Olivier

Any fiber can be dyed with oak gallnuts. It is used to increase lightfasntess

Oak Gallnut can be used to create dark shades with madder or indigo on wool and silk with minimal use of iron sulphate

This gallnut extract was especially developed for textile and natural dyeing uses : 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
