Cork had written records in the Spring and Autumn and the Warring States period.Cork is composed of dead cells that accumulate on the outer surface of the cork oak tree. Because of its honeycomb-like structure, cork consists largely of empty space; its density (weight per unit volume) is one-fourth that of water. Unlike a honeycomb, however, cork consists of irregularly shaped and spaced cells having an average of 14 sides. With 625 million of these empty cells per cubic inch (40 million per cubic centimeter), cork is like many layers of microscopic Bubble Wrap, making it an effective cushioning material.
Cork oaks are harvested every nine years,Cork is harvested, by hand, during spring and summer months, as the cork trees experience the most rapid growth during this period.
Cork is an extremely unique material, due primarily to its unmatched cellular structure. Due to its minuscule air-filled cell pockets, cork is a lightweight, low-density material that has incredible buoyancy,cork absorbs neither dust nor moisture, and it resists both rot and insects. Highly resistant to wear, it is used for polishing diamonds.
