Cork’s elasticity combined with its near-impermeability makes it suitable as a material for bottle stoppers, especially for wine bottles. Cork stoppers represent about 60% of all cork based production. Cork’s low density makes it a suitable material for fishing floats and buoys, as well as handles for fishing rods (as an alternative to neoprene). Sheets of cork, often the by-product of more lucrative stopper production, are used to make floor tiles and bulletin boards. Granules of cork can also be mixed into concrete. The composites made by mixing cork granules and cement have low thermal conductivity, low density and good energy absorption. Some of the property ranges of the composites are density (400–1500 kg/m³), compressive... »View More

The history of wine spans thousands of years and is closely intertwined with the history of agriculture, cuisine, civilization and humanity itself. Archaeological evidence suggests that the earliest wine production came from sites in Georgia and Iran, dating from 6000 to 5000 BC. The archaeological evidence becomes clearer and points to domestication of grapevine in Early Bronze Age sites of the Near East, Sumer and Egypt from around the third millennium BC. Evidence of the earliest European wine production has been uncovered at archaeological sites in Macedonia, dated to 6,500 years ago. These same sites also contain remnants of the world’s earliest evidence of crushed grapes. In Egypt, wine became a part of recorded history, playing an... »View More
