Bianco Cararra C Lorano

Bianco Cararra C Lorano
quarry of origin


Carrara, Italy
Petrografic name (according EN 12407): Marble
Macroscopic description: A medium-fine-grained lithotype, pearly white verging on light grey in colour with dark grey veins of a vaguely sub parallel orientation and dark grey patches up to millimetric in size in places. The material is compact and there are no surface pores.
Technical data provides a frame of reference only. As stone is a product of nature, up to date testing to determine specific physical qualities should be repeated for each major project. We decline any responsability for the mis-use of this data, since said data is sourced from the quarry.

Block and slab characteristics
Average size of blocks: 3,00 x 1,70 x 1,70m. Slabs are preferably cut against the grain or perpendicular to the grain, i.e. the hard way and the easy way.

Microscopic description according to EN 12407 e EN 12460
An isotropic metamorphic lithotype, that is anisotropic where the veins occur. The material is composed of blasts that are subeuhedral and euhedral in the suborder with sutured/linear or rounded grain boundaries of a seriate size (from 50 to 400 μm). There are also millimetric nodules in places composed of larger crystals (500-900 μm) and veins composed of calcitic microblasts (approx. 40 Ám) and rhombic dolomitic blasts clouded by opaque minerals, acicular muscovite, rare poikilitic quartz with inclusions and widespread pyrite microcrystals (< 30 μm).
