Oak bark contains high concentrations of tannins, particularly gallotannins and ellagitannins, as well as phenolic compounds that give it strong astringent and color-active properties. In combination with mordants such as alum or iron(II) sulfate, stable brown, gray and black tones are created, which played a central role in historical dyeing and ink production.
Due to its high tannin content, oak bark can serve as both a dye and a fixing component. The polyphenols it contains form complex compounds with metal ions that stabilize pigments and improve their adhesion to fiber and paper substrates. In combination with iron-containing solutions, so-called iron gall complexes are formed, which have excellent lightfastness and were used early on as a basis for natural document and drawing colors.
In plant dyeing, ground oak bark can also help regulate pH and extend the shelf life of plant extracts. Its structuring properties have an emulsifying effect and support the formation of uniform color bases.
Oak bark is thus one of the most traditional raw plants used in natural dye production - versatile as a dye, mordant or additive and an impressive example of the sustainable use of plant tannins in historical and contemporary dye production.

All our products are intended exclusively for artistic use and must not be consumed or used externally or internally by humans or animals. In addition, all our dried plants can be stored for several years without losing their quality. Further information on our dried plants and instructions on correct storage can be found in our product data sheets.
Our packaging sizes are primarily aimed at individuals. Therefore, we mainly offer small quantities. However, for educational institutions or customers who work with larger groups, it may make sense to order larger quantities. For orders of 1 kg or more per item, we can usually arrange a separate delivery as a complete package. Since we usually have to order these larger units separately and check availability with our suppliers in advance, we recommend a lead time of at least two weeks.
In our online shop, we can only offer you some basic information about our products. If you would like to delve deeper into the world of plant dyes and expand or deepen your knowledge, we recommend our workshops at Hof Emschermündung or at one of the globally active Dialogers.
We would love to sell only organic products. Unfortunately, this is often not possible, as many of our dried plants are not available as organic products from our suppliers. This is usually because small businesses often cannot afford this certification, even though their products are already manufactured according to the relevant standards. Larger companies pass on these certification costs to their customers and therefore have to offer their products at a higher price.
For our shop, this means that we only offer products with an organic label that we can purchase at a fair price. Of course, we place great importance on carefully selecting our suppliers and always ensure high product quality - this also applies to our dried plants that do not carry an organic label.
