Cork on water and under water

The unique nature of cork is underappreciated!

All of us are aware of the cork used in bottles, many of us are familiar with decorative cork surfaces for floor, wall and ceilings. Perhaps someone has used shoes with cork soles or insoles…

Did you know that cork oak bark is widely used in the vast seas and oceans? Navigation buoys and floats are still made from cork to this day.

In the age of plastic and synthetic materials, no worthy replacement could be found for the core of navigation equipment made of cork which is salt water resistant and light, possessing great floating properties.

The same centuries-old dependence exists in the fishing industry: in modern fishing nets, cork floats are also used and there has been no sustainable replacement for them.

Water sports and swimming leisure activities also have a lot to do with cork. Swimming and surfing boards; various kayaks and canoes are mostly made of high-density pressed cork pellets. A popular hobby and job for some: Fishing with a rod also uses products made of cork: rod handles and floats.

Cork is also used in the dark depths of seas and oceans. Most modern nuclear submarines are equipped with special soundproofing walls made of cork granules and very thick metal shields. After all, one of the key requirements of submarine, despite its huge size, is to be almost entirely silent.

So, tell me: what exactly is cork? Is it just a bark of an oak tree or something more?

Scientists have discovered the remains of a Phoenician ship more than three thousand years old, some elements of which were made of cork oak bark: in this way, the Phoenicians sought to improve the ship’s buoyancy, reduce its weight, and improve its ability to maneuver swiftly.

Summing up the above, we see that cork is indispensable both on land and on water. Its significance for humans is truly enormous both millennia ago and also in the modern world.
