Concordsilver
Marble
Structure: Constantly fine-grained grey-whitish marble with weakly silvery glow. Grey veins and clouds pull through the rock and results in a lively, varied structure, which makes numerous coloured design possibilities possible. Today the CONCORDSILVER is a standard material; it was already used of the Romans in numerous ancient architectural monuments. In order to obtain a general impression of the rock, prototype sample are not sufficient usually. Thus a wide sampling to get 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 CONCORDSILVER possesses a degree of hardness from 3 to 4 and counts thus to the soft rocks. Due to its composition the CONCORDSILVER is frost-sensitively (thus only to be used in the internal area). As a soft rock the CONCORDSILVER is not scratch-proof and has to be protected from acids.
Emergence: Marble results in principle from metamorphosis (rock recrystallization) from limestone. The CONCORDSILVER developed from an old limestone massif with small clay content and remainders of organic material (carbon), which was converted under the influence of pressure and temperature within the earth's crust to marble. The grey streaks and clouds resulted from clustering of the clay/tone minerals and carbon during the recrystallization.
Age: Approx. 150 million years (Jura).
Use: In the interior decoration, mainly as floor mats, wall linings, baths and stairs.
