Cork - a gift from Africa

Cork is a gift from Africa, as one famous character from the Soviet movie said. This material, which is one of the lightest solid natural bodies, which are closely spaced dead plant cells (bark).

The properties that cork has are used in the widest possible way:


- low thermal conductivity
- low sound conductivity
- impermeability to most liquids

Naturally, corks are most often used to clog bottles. Due to its good compressibility, the cork can be forced into the neck by force, where, due to its elasticity, it is firmly pressed against the walls. Only wet and especially steam-heated cork possesses these properties to a high degree. Drying, the cork shrinks significantly, like a tree, and becomes stiff. Therefore, when corking wines, beer, etc., the cork is pre-welded. Using special machines, through the lever and piston, the plug is pushed into the substituted neck through a funnel-shaped tube.

However, do not forget that cork is also an excellent material for making crafts do it yourself. You can get to know them on the pages of our site. For example, after reading an article "Cork Wine Crafts"

An interesting fact is that even famous people made crafts from corks - John Pollack, Bill Clinton's speechwriter, who collected corks for thirty years, built a ship weighing 1600 kg from 160,000 wine corks. He sailed on this boat 265 kilometers along the Portuguese river Douro and was nicknamed Cork Captain.




The word "cork" means not only material for clogging bottles, but also a collection of machines. So here are the most crowded roads in the world - in Luxembourg: there are 570 cars for every thousand people. Surprisingly, there are almost no traffic jams in Luxembourg.
