Cork

cortiça

It is a material of vegetal origin of the bark of cork trees, light and with great insulating power. The reason cork has these characteristics is its composition rich in suberin, a lipid (greasy) substance that accumulates in the cell wall. The presence of this substance in a first stage prevents the entry of pathogens and any toxic substances in the cell and at a later stage the passage of nutrients to the cell, causing its death.


Extraction

The first extraction of cork occurs, usually, when the tree reaches between 25 and 30 years, and the extraction occurs in the months of June to August. This cork, sometimes of considerable thickness, is called virgin and is distinguished substantially from the cork of reproduction extracted in the following periods: it is designated by secondary in the second circulation and by amadia in the subsequent runs or extractions. The cork amadia is the one of better quality, being therefore the most valued, and the only one that can be used for the manufacture of stoppers. From this stage, cork is extracted every nine years.
