The ceramics & inorganic materials conservators are responsible for the preservation and restoration of ceramics, glass, stones, sculptures and other siliceous objects. Apart from implementing conservation programmes for the related collections, conservators have to conduct regular maintenance programmes for outdoor sculptures and works of public art with the Metals unit, which are all subject to the unfavourable climatic and environmental conditions of Hong Kong.

With the recent commissioning of the Public Art programme, a large number of sculptures of different material nature have been installed at various venues in the territory. Given Hong Kong's sub-tropical climate, the artifacts are subject to the unfavourable climatic and environmental conditions of Hong Kong. Conservation staff thus have been busy coping with the conservation demand arising from such in recent months.
