Cork is a lightweight, buoyant material harvested from the bark of the cork oak tree, primarily found in Portugal. This unique tree can live for over 200 years, and its bark can be stripped every nine years without harming the tree. Cork is most commonly used for making wine stoppers, but it also has applications in flooring, insulation, and crafts due to its natural properties. One of the remarkable features of cork is its ability to compress and expand, making it an excellent sealant. Additionally, cork is eco-friendly, as it is a renewable resource. Its natural texture and appearance add a touch of warmth and style to various products, making it popular in both functional and decorative items.
