The cork oak - Quercus Suber L - appeared more than 60 million years ago, in the Western Mediterranean. Man quickly learned how to extract, work and use the renewable bark of this noble species.

The exploration of this resource is an excellent example of the relationship between Man and Earth, and the respect for the ecological model.

Cork , the bark of the cork oak, is a vegetative material, composed of micro cells, which are generally of polyhedric form. The intercellular spaces are filled with a gas composition, identical to that of air.

The special characteristics of cork and its multiple applications are due to the honeycomb structure and the nature of the cellular membranes.
