Oak galls are excrescences that are sometimes produced in great numbers on the tree and are caused by the activity of the larvae of different insects. The insects live inside these galls, obtaining their nutrient therein. When the insect pupates and leaves, the gall can be used as a rich source of tannin, that can also be used as a dyestuff. The galls have been used as a dark dye for the hair. Acorn meal has been used to mend cracks in clay pots.Wood - coarse-grained, heavy, hard, strong, very brittle, not very durable.
