Парче мрамор

Мраморът е метаморфна скала, изградена от калцит или доломит, т.е. калциево-магнезиев карбонат, който е рекристализирал под влияние на температура, налягане и водни разтвори. В търговската практика той включва всички декоративни скали, богати на калций, които се поддават на полиране.[1] Оцветяването варира от чисто бяло до всевъзможни нюанси на цветовете. Мраморните скали се образуват при метаморфизъм на варовици и доломити.

Най-често срещаният е бял мрамор. Обемите на този камък са огромни и има големи находища в САЩ, Африка, Франция, Куба, Гърция, Норвегия, Италия, Франция. В България мрамор се добива в планините Рила, Родопи, Странджа, Пирин и Берковска.[2]

Прилага се в бита – за облицовка, мозайки, производство на цимент и вар; в скулптурата, в огнеупорната, стъкларската и металургичната промишленост.
