• Botanical name: Quercus infectoria (Aleppo oak)
• Origin: Turkey (Mesopotamia region)
• Sizes: 100 g (3.5 oz), 400 g (14.1 oz), 1 kg (2.2 lb)

Green or white oak gall: which one should I choose?

Green oak galls generally have a slightly higher tannin content than white oak galls. Both are naturally rich in tannins and work well for mordanting cotton, linen and other cellulose fibers. For most natural dyeing applications either option works well. You can also see our white oak gall powder.

Quick use

1. Scour your fabric first.
2. Use 5-10% WOF in a tannin bath.
3. Continue with mordanting and dyeing as needed.

Notes

Natural batches may vary slightly. Avoid inhaling fine powder and store sealed in a cool, dry place.
