Characteristics of birch cork

The animations are intended for presentations. They help scientists to explain why birch cork behaves differently than other tree bark.
In the archaeological context, preserved organic objects made of birch cork are extremely rare. In order to ensure the long-term conservation of such finds, Johanna Klügl and Giovanna Di Pietro have characterised birch cork and studied its degradation processes. After a long period of research, they have found out how best to conserve finds made of birch cork.

As the birch grows, the cells in the birch cork change.

The cells are stretched tangentially and compressed radially.

There are different numbers and lengths of cells. As a result, the cork curls up after the harvest.
