Tannins are a basic ingredient in the chemical staining of wood, and are already present in woods like oak, walnut, and mahogany. Tannic acid can be applied to woods low in tannin so chemical stains that require tannin content will react. The presence of tannins in the bark of redwood (Sequoia) is a strong natural defence against wildfire, decomposition and infestation by certain insects such as termites. It is found in the seeds, bark, cones, and heartwood.
Tannic acid is a common mordant used in the dyeing process for cellulose fibres such as cotton, often combined with alum and/or iron. The tannin mordant should be done first as metal mordants combine well with the fibre-tannin complex.
