Sandscraper

Our buildings and monuments are under attack. Microbes have been at it for
ages, but now industrial pollutants have joined the fray. In Carbonate
Stone, K. Lal Gauri and Jayanta Bandyopadhyay describe the mechanics of
carbonate deterioration, and use case studies of the Sphinx and San Diego’s
California building to illustrate the art of conservation technology. Published
by Wiley Interscience, £78.59, ISBN 0471179779.
