Oak is the first of the dye sources detailed in The Colourway, as a dye source the leaves are rich in tannin and can provide a surprising range of natural hues.
In ancient Ireland, the Oak held special meaning to the Celts. Considered the King of the forest, it was associated with strength, nobility, inspiration & knowledge. The Oak itself has a lineage dating back roughly 85 million years. Historically, the oak was essential to the Irish way of life, providing shelter, fuel, building materials, food & habitats for wildlife.

With over 500 hundred species of Oak, they are known for their longevity & can live for 300-400 hundred years. With deciduous & evergreen varieties they are characterised by their wavey leaf pattern & distinguishable acorn seed.

As a dye plant, the leaves, bark, acorns, twigs & oak galls can all be used to create colour. These parts contain tannin which acts as a natural mordant ensuring beautiful long-lasting colours on plant fibres. The oak galls contain the highest concentration of tannin & these are commonly used to mordant plant fibres such as linen, cotton or hemp. They have also been used throughout history to create dark greys & ink when combined with iron.
