| Summary: | This article discusses the significance of certain replicas in museums, focusing on medieval seal impressions from the ‘Hallepoort’ collection at the Royal Military Museum in Brussels, Belgium. We highlight a shift from traditional imprinting methods to casting with plaster and sulphur in the late 19th and early 20th centuries An analysis by the Royal Institute for Cultural Heritage confirmed sulphur’s presence, highlighting conservation challenges due to its flammability and potential to cause chemical reactions that could damage surrounding objects. In response, measures such as fire safety protocols, controlled temperature and humidity, and better ventilation are implemented to protect the casts. |
