Uses of Cork

Cork is a natural substance that is extracted from the cork oak tree. It is considered to be a sustainable and environmentally friendly product because the tree is not harmed during harvesting. It is a useful material because it has elastic properties, is virtually impermeable (fluid doesn’t pass through it), it floats and is fire resistant. Most cork is harvested from Portugal (53%) and Spain (30%).It is best known as a stopper for wine bottles, but it has many other uses as well.
