Birch bark

Description

Thin sheets peeled from the inner bark of the birch tree. Birch bark was used as a textile and writing paper in India and the Far East from at least the 2nd century. For preparation, the strips were pulled from the tree, dried, then softened with oil (Batton 2000). The strips were laminated using a natural gum then flattened between wooden covers.
