Cottaer sandstone.

Description of the stone: The stone’s appearance is elegant and modern. It is a very fine-grained grayish-white to yellow sandstone featuring a siliceous binding. The color variations can mirror the stratification but also be lively and irregular, appearing even cloudy or with knots. Wavy clayey films embedded in the stratification give it its typical marbled structure.

Peculiarities of the stone: Cottaer is one of the famous Elbe Sandstones (in German: Elbsandsteine), which also include the Postaer and Rheinhardsdorfer. Due to their beauty and durability, they were the preferred materials for representative buildings of the Saxon and Prussian kings. Recently, Cottaer sandstone was used, e.g., for the ventilated and partly massive and self-supporting natural stone facade of the Yee Potsdam building. Another example is the ventilated facade of the Freiberg Mining Academy’s lecture hall (approx. 620 m² facade, approx. 720 m² roof, and approx. 55 m² ceiling cladding).

Sandstone from Saxony was very popular already in the Baroque period, and in the 19th century, it was even shipped to Russia, Scandinavia, and Cuba for technical applications. In the German Democratic Republic (GDR) after 1945, the company was nationalized and renamed “VEB Elbenaturstein.“ After the unification of Germany in 1990, the founders‘ successors took it over again. The company philosophy includes the cultivation of traditional stonemasonry and the use of state-of-the-art CNC machinery to produce large series.
