Towards International Designation of a Heritage Dimension Stone

The Global Heritage Stone Resource (GHSR) designation has been proposed to recognise dimension stone types that have achieved important utilisation in human culture. Within internationally recognised rules, a GHSR will be determined on the basis of significant use in human history, wide geographic range of utilisation, and the benefits that would accrue from designation. Nominations will include a detailed description that allows professionals to introduce new scientific terminology, define geotechnical properties, identify the specific geographic/geological occurrence, and also the characteristic texture, colour and variability that contribute to aesthetic suitability for use. GHSR designation will have significant value for all professional groups that work with stone. The necessary GHSR delineation, including current and former quarry sources, will help to facilitate the safeguarding of resources for future use. Specific GHSR geotechnical characteristics associated with a formal name could also aid the development of specific geographical designations for stone, similar to those being currently applied in the European Union for foodstuffs. The international rules will provide a succinct pathway for GHSR designation with the assistance of a governing Board. A draft check list of essential GHSR properties has been prepared and tested using trial citations for “Portland Stone” and “Welsh Slate” from the United Kingdom.
