Somewhere near Kaolun
Mining is in full swing, but there are also places where time has stood still. On one of the buildings, the faded communist slogan “FOR THE EARLY FULFILLMENT OF TASKS” is still visible today, a reminder of a time when industry was a symbol of progress and achievement. Kaolin is one of the raw materials that has a long tradition in Czech industry and remains very important to this day.
Kaolin is a fine-grained white rock composed primarily of the mineral kaolinite. It is formed through the long-term weathering of feldspar-bearing rocks, such as granite. Thanks to its white color, fineness, and resistance to high temperatures, it has become an important industrial raw material used in many fields.
It is typically white to light gray in color, soft, and easy to process. When mixed with water, it forms a plastic mass suitable for shaping, which is why it is irreplaceable, especially in the production of porcelain and ceramics. However, it also finds applications in other sectors—it is used in paper manufacturing, construction, the production of paints and varnishes, cosmetics, and the pharmaceutical industry.
Even today, kaolin remains a raw material that modern industry would find difficult to do without. And although mining continues in full swing, some areas around the mines still bear traces of the past, reminding us of a time long gone.
