The British Museum Research Laboratory was founded in 1920. The Laboratory’s scientists provide insights into the past through research on the collection. Using both traditional and the very latest methods and equipment they are able to answer questions that help with the interpretation and understanding of the collection. Their discoveries can tell us what objects from the Museum’s collections are made out of, how they were made, when and where they were made and what that tells us about their history.
