Conservation work on National Slate Museum objects 16 April 2026 Conservation is at the heart of the National Slate Museum redevelopment project and our conservation team are already hard at work assessing and working on the collections to make sure they look their best and keep them safe so that they can be enjoyed for generations to come when the Museum reopens. Jennifer Griffiths is Senior Conservator of Industry Collections and is one of several team members working on the National Slate Museum collection. here she tells us a bit more about her work. “I’ve started my part of the conservation work with treatment of a pay trolley." said Jennifer." This wooden cabinet contains 49 small pay tins made from tin-plate. The cabinet and all of drawers within the cabinet were extremely dirty with surface and ingrained dirt and the tins, all very heavily corroded. The cabinet can be seen here before and after conservation." "So far, the conservation of the cabinet and 7 of the tins has taken a total of 45 days' work.""Each pay tin takes 2 days to complete and so far, 7 tins have been completed.""Just 42 tins to go!"Over the next few months we'll be taking a closer look at all the other conservation work taking place including cleaning our wooden pattern collection, paper and artworks, furniture and clothing!
