NSI Attends 10th International Congress on Deterioration and Conservation of Stone

Members of the NSI participated in the 10th International Congress on Deterioration and Conservation of Stone held on 27 June – 2 July 2004 in Stockholm, Sweden. This Congress, attended by some 250 delegates, was expertly coordinated by ICOMOS Sweden. It was a wide ranging meeting at which there was opportunity to learn about the application of scientific research into a variety of repair and conservation projects. Topics discussed included conservation methodologies, material properties and treatments. On this international stage Scottish presentations were given by Ingval Maxwell (Historic Scotland) who chaired a Workshop on Facade Cleaning Techniques, Andrea Hamilton (Edinburgh University) on mechanics of sodium sulphate crystal growth and Ewan Hyslop (British Geological Survey) on sourcing and supply of replacement sandstone in Edinburgh’s New Town. The BIODAM research (involving many European partners including the Robert Gordon University and Historic Scotland) was also presented.

Throughout the meeting there was much exchange of ideas and debate on the philosophies and practice of conservation. A number of presentations described interesting state-of-the-art science but there is a great need for the science to be ‘translated’ for the benefit of a range of practitioners. During the Stockholm meeting the NSI was represented at meetings of the ICOMOS International Scientific Committee on Stone and we are delighted to announce that the NSI has been nominated as an Associate Member of this body. Much effort is currently being devoted to the completion of a multilingual illustrated glossary on stone deterioration which will be made available in the ISCS’s web site.

Excellent tours of Stockholm’s Old Town and Drottningholm Palace, together with a memorable Reception at the City Hall and an atmospheric Congress Dinner at the Vasa Museum, combined to make this an outstanding event.
