Rivierawhite
Marble
Structure: The RIVIERAWHITE is a fine-grained, bright marble.
Grey veins beside a bright basic clay which run netlike or punctiformly - depending upon spatial process - over the entire rock, are characteristic for the RIVIERAWHITE. The sampling of RIVIERAWHITE is quite difficult because of the changing texture and different brightness stages. Usually prototypes are not sufficient in order to obtain a general impression of the rock. Thus a wide sampling to the switching of an impression and the effect of the rock is recommended. Small, open places so-called "Tarolli" on the surface are possible and belong to this material.
Characteristics: After the MOHS´ hardness scale (1 = chalk, 10 = diamond) the RIVIERAWHITE possesses a degree of hardness from 3 to 4 and counts thus to the soft rocks. Due to its composition the RIVIERAWHITE is frost-sensitively (thus recommend only for the internal area), is as soft rock not scratch-proof and has to be protected before acids.
Emergence: Before approx. 200 million years bodies and skeletons of sea organisms sank onto the ground of a warm, flat sea, which were solidified to limestone. Approximately 30 million years ago the movement of the two tectonic plates Africa and Europe began. The sediment layers were chemically changed and deformed in large earth depth under several million atmospheres pressure and under very high temperatures. The soft limestone became crystalline marble (metamorphic rock), which was later high piled to the current mountains. There are approx. 50 different sorts in Carrara.
Age: Approx. 150 million years (Jura).
Use: Interior decoration; mainly floor mats, wall linings, baths and stairs.
