Dolomitic Plasters in Indian Monuments and its Characterization

Research reveals that dolomitic lime, rather than the more common Carboniferous limestone, was used in plasterworks at UNESCO World Heritage Sites such as Alampur (6-7th AD) and Lotus Mahal, Hampi (1336-1570 AD). This finding indicates a higher risk of damage due to wetting and necessitates specialized conservation efforts. The study analyzed mineralogical and chemical compositions, showing that hydraulic components were added to enhance durability in Alampur's plasters. Additionally, variations in the ratio of binder to inert materials suggest differing provenances for Hampi's plasterworks, complicating provenance studies. These insights provide critical data for technological evaluation and guide conservators in re-plastering efforts.
