Beola grigia

 

Striped texture orthogneiss with heterogeneous grain and close yet discontinuous schistosity plans. The rock is characterised by a whitish background with irregular aggregates of finely grained laminar biotite. On the whole the rock has a rather even grey colour. It is exactly because of this soft refined colour that it is considered a valuable material.
Uses: indoor and outdoor floorings and coatings, stairs, fountains, columns, kitchen and bathroom table-tops, flower-holders, skirting units, threshold, window-sills, window surrounds, portals, frames, sills, benches, kerbs, road paving,funerary art, graves and chapels.
