Database of Implement Petrology for Britain

The Database of Implement Petrology for Britain contains records assembled by the Implement Petrology Committee of the Council for British Archaeology between the 1930s and the mid 1980s. The database contains contains the results of examining more than 7,500 stone implements from the British Isles. These artefacts range in date from the earliest Neolithic to the Bronze Age; in type from polished battle axes to net sinkers; in quality from the finest jadeite axe to the crudest roughout; and in composition from mudstone to porcellanite. Many come from known rock sources and places of manufacture, as far apart as Land's End in England, the Northern Isles in Scotland, Ireland and the Channel Islands. Together these implements comprise an extraordinarily extensive and varied cross-section of the stone tools and weapons made and used in Britain over a period of at least 3,000 years.
