I came across these metallic rock artifacts at the 1300 years old Teevardev Buddhist Monastery and some 'metallic' pillars adjacent to it in Sirpur, Chattishgarh. These are made up of overtly iron rich rocks that does not rust but takes on a twany colour. This region on the banks of the Mahanadi River has some strange rock formation. Most sculpture at Sirpur are made up of fossilised pink sandstones, some are metallic and some structures are built out of white limestones....such variety of raw materials is unheard of in any other site.
