Name: Buckthorn Seed | Whole
Scientific Name: Rhamnus Petiolaris Boiss
Also known as Anatolian buckthorn, Persian berries and sea buckthorn, the seeds of these plants can be used to create a range of shades including orange-yellow, yellow, beige, green, and khaki, depending on the mordant and modifiers used.
How buckthorn seed is produced:
Our buckthorn is grown by producers nearby. The species is common in Central Anatolia, where it grows on rocky soil at altitudes of 3,300 - 8,300 feet. The plant’s insignificant greenish-yellow flowers produce berries that remain green for several months, eventually turning brown or black. The berries are harvested, dried naturally, and then powdered.
Historical use of buckthorn:
Buckthorn species, especially sea buckthorn, were used in medicine since the 7th century BCE . In the 17th century buckthorn was used as a purgative in England, being the only native plant used for this. Its use in the production of pigments dates back at least to the Iron Age, with archaeological samples from that period having been discovered in Finland.
Ensure your fiber/fabric has been properly scoured and mordanted before use.
Use between 30-50g buckthorn seed powder to dye approximately 100g of fiber. The more powder you use, the darker the colors you will be able to achieve. Buckthorn powder is suitable for hot and all-in-one dyebath techniques.
Charlotte Treglown used our buckthorn seed powder. She said:
I used themazi’s buckthorn seed dye on cotton and wool. I mordanted my cotton with their oak gall tannin, followed by alum with soda ash. The wool fabric I used was mordanted with alum. The buckthorn dye gave me some really beautiful strong golden yellows, which I was able to modify to olive greens with iron. I also obtained some lovely mustard and darker brown/green shades by increasing the pH with soda ash and then dipping in iron. I was delighted by how strong the colours were.
