Biological growth on stone sculptures
Lauren Cato, a student at Columbia Univ. in New York City, is working on her thesis on the significance of biological growth on stone sculptures in historic gardens. Her interest is in conservation theory, and more specifically, in the process of planning for conservation and how we decide whether or not to clean. Lauren is finding it difficult to find inter-disciplinary information on this subject amongst the areas of garden history, architectural history, art and architectural conservation, can you help?
