Oak Bark

Oak Bark

Oak Bark contains very high tanning levels which makes it perfect for tanning animal skins and dying cellulose fibers.

North American Oak Bark gives a yellow color to the dye bath, while Mediterranean oak bark can give off shades of red.

Black oak bark was first introduced to England from Wilmington Delaware. 

When Black Oak Bark is allowed to sit and soak for two years it can be used as a mordant.
