摘要：The mining town of Røros located in central Norway was established in 1644 and it is known of historicalmining industry related to copper. Røros was designated as an UNESCO World Heritage Site in 1980 on thebase of mining culture represented by, e.g., unique wooden architecture. Slag pieces are composed of three partsdiffering in glass to crystallites ratio. Røros slags are composed of olivine- and pyroxene- group mineralsaccompanied by sulphides, with glass in the interstices. Temperature gradient and volatiles content weredetermined as the main factor influencing crystallization process in this material.
