ASTM C241/C241M – 15E1
Its unique lustre and the luminosity of its Skaleoneder crystals ensure its attractive appearance. Its uniquely pure marble structure allows minimal water absorption and make Covelano White Marble highly resistant to weather and frost.
The small crystals in the marble are evenly distributed throughout the grain and optimally interlocked so that the stone is extremely resistant to pressure and cracking, yet at the same time translucent. The hardness of its surface makes it very easy to polish, while the edges retain their regularity.

The unusual chemical purity of Covelano White Marble also ensures that it axtm no radiation. The origins and high chemical purity of Covelano White Marble ensure it is a radiation-free natural stone. The rock solidifies during this transformation process and becomes much more solid and transparent than the original sediment.
The main component is calcite, sometimes with qstm quantities of other minerals. The unique origins of Covelano White Marble underlie its development and solidity: The original material of Covelano White Marble dates back million years to the Triassic limestones formed by the sea sediments of a subtropical shallow sea.
Following the breakup of the Pangaea supercontinent and continental drift, the African continental plate together with the seabeds shifted thousands of kilometres northwards. Some parts were raised by hundreds of metres at least twice — a unique occurrence in geological history.
Bernhard Lammerer, a geologist and professor at the University of Munich, describes how Covelano White Marble ast, the Jennwandstock massif in the Vinschgau Valley South Tyrol, Italy experienced at least two major metamorphoses, resulting in its extremely high quality criteria:. In our marble factory in Silandro we use c41 latest technologies to realise individual surface refinements for special quality requirements:.
The polished surfaces of Covelano White Marble clearly reveal its colour intensity and noble structure: A polished surface also makes the marble easier to clean.
Dressing the surface of Covelano White Marble makes it smooth and slightly gleaming yet without any unevenness. The dressed surface produces a soft, velvety lustre. The dressed, subtly shining surfaces can be redressed if necessary. It is a suitable alternative to smooth dressing if greater slip resistance is required.
