WARRINGTON, ENGLAND—White crystals have been removed from a 4,000-year-old Egyptian mummy case at the Warrington Museum and Art Gallery by Tracey Seddon of National Museums Liverpool. The wooden coffin had been reused for a man named Pa-ikh-mennu, who worked at the Temple of Amun in Luxor. “The crystals were developing on areas of restoration carried out 30-40 years ago. They were causing the paint to crumble and lift,” Seddon told Culture 24. She secured the loose paint with conservation-grade adhesive, or removed it if it was too crumbled to save. The Egypt Exploration Society donated the artifact to the museum in 1905.
