Preservation of pre-historic monuments and buildings from the effect of desert varnish

Desert varnish is the thin red to black coating found on exposed rock surfaces in arid regions. Rajasthan, which is located on the western side of India and a part of the Great Indian Desert, has artistic and cultural traditions which reflect the ancient Indian way of life. There is a rich and varied folk culture and ancient monuments which are often depicted symbolic of the state. It makes Rajasthan very important for tourism perspective. Latterly, almost all prehistoric forts and monuments of Rajasthan are affected from dark coatings of desert varnish and losing their elegance and charm, which makes it very imperative to find suitable measures to bring back the attraction of these monuments.
