Acorn Extract | Tanin Extract

The Acorn Natural Dye Extract is derived from the fruit of various oak trees (Quercus species), predominantly native to the northern hemisphere. With over 500 varieties of oak, our extract is sourced from Turkish Quercus macrolepsis. Acorn tannin is known for its excellent wash and light-fastness properties, making it ideal for creating ginger brown colors or as a tannin in a mordanting process.

Production of Dried Acorn Extract Powder:

Our acorn extract powder is produced in collaboration with a local Turkish company. The process involves harvesting fully ripened acorns, separating them from their cups, and utilizing the cups with their high tannin content to create our extract. The acorns themselves are also utilized in flour production and as feed for livestock.

Historical Use of Acorns:

Throughout history, acorns have been a significant food source for both humans and animals. High in tannins, they require processing to remove bitterness. Acorn flour was commonly used, and during the American Civil War and World War II, acorns served as a coffee substitute. Additionally, acorns have medicinal uses for treating inflammation and kidney stones and are used in livestock feed. Acorn cups have traditionally been used in the leather tanning industry.

How to Use Dried Acorn Extract / Acorn Tannin Powder:

• To Dye Fabric/Fiber: Ensure the fabric/fiber is properly scoured. Use at least 20g of acorn extract powder for every 100g of fiber. Suitable for cold, hot, and all-in-one dyebath techniques. For an all-in-one dyebath, pour boiling water over the powder, allow it to cool overnight, then simmer the mixture with the fabric/fiber for an hour. Leave it for several hours or overnight, stirring occasionally. Darker shades can be achieved with iron sulphate.

• As a Tannin in Mordanting: Use 10g of acorn extract powder for every 100g of fiber. Pour boiling water over the powder and let it cool overnight. The next day, bring the tannin bath to a gentle simmer, add the fabric/fiber, and let it soak for several hours or overnight, stirring occasionally. Follow with an aluminum mordant and an optional second tannin soak.

Reviews:

adyeingartitaly, a photographer and natural dyer, praised our acorn extract tannin: “The acorn extract was a real surprise. It gave beautiful shades without the addition of mordants. I really recommend it to everyone approaching natural dyeing for the first time. It's very easy to use, needing only a pot with hot water.”
