The cork begins in the tree
On the cork oak, the bark is one of the first clues.

Quercus suber has a thick, elastic peel and deeply split: cork. The municipal description includes corks on the half slopes of Cabeceiras. The leaves persist for more than one season; the University of Évora refers up to three years. Persistent foliage does not mean that each leaf lasts forever.
Fruits are acorns. The fiche describes the dome that accompanies them with long and velvety scales. Casca, leaves and fruits offer different clues to observe the tree, without removing cork or pulling branches. The local reference documents the landscape; the botanical description explains general characteristics of the species.
Inside, cork has a structure of microscopic cells with air-like gas. APCOR relates this organization to lightness, compressive capacity and form recovery. The suberin present in the cell walls helps to hinder the passage of liquids and gases. A cork seems simple, but the behavior of the material begins on a scale that the eyes do not reach.
The association also describes the transformation of corks used in granules for new products, such as coatings and soles. It is a general example of reuse, not an industrial activity confirmed in Cabeceiras. Compare with the punches of Outeiro and the containers of Faia: are other stories of materials linked to trees, with different functions and ways of working.
