Bianco Lunetia
Carrara, Italy
quarry of origin: Carrara
Petrografic name (according EN 12407): Marble
Category: marble
colour: White
Macroscopic description: It comes from the Carrara quarry that Fibra reactivated after years of inactivity. It is fine-grained and therefore possesses high hardness and is easily polished.
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.

Microscopic description according to EN 12407 e EN 12460
A heterogeneous crystalloblastic metamorphic lithotype. The material has a crystalline mosaic structure composed of euhedral/subeuhedral calcitic blasts (from 100 to 350 Ám) with rounded or straight grain boundaries. The structure is isotropic. Rare opaque minerals and acicular muscovite are spread throughout the calcite. The veins are composed of crystalloblastic mosaics that are structurally different and up to submicroscopic in size. The form of the crystals is mainly subeuhedral with sutured grain boundaries. There are microgranulations of opaque minerals often associated with titanite that sometimes formally define the veins. There are pyritic crystals (<4 mm) with coronitic structures where the calcite can reach the maximum dimensions of 1 mm.
