The Conservation Department is responsible for the physical care of the glass collections and of glass-related objects, and advises on exhibition and storage conditions for the glass collection and objects loaned from the Museum for exhibition.

The museum’s collection includes nearly 50,000 objects, and ranges from the very earliest 2nd millennium B.C. glasses to contemporary objects, which means we have a wide variety of glass to look after. Conservation involves proper handling, storage, cleaning, repair, and restoration. The repair of broken objects is one of the most difficult conservation tasks and requires careful documentation, skill, patience, and the understanding of modern synthetic adhesives.  Restoration goes beyond the repair or re-assembly of broken fragments, and entails the ethical and aesthetic replacement of missing pieces, primarily for publication or museum display, but sometimes for structural support for very fragmentary objects. Our mission is to leave the collection in better condition than we found it; it is extremely important that anything we do can be easily undone, so as to maintain the integrity of the objects and their future preservation.

The Conservation Department also advises on the safest methods of displaying, mounting, lighting, storing, and handling glass objects, including all new acquisitions and loans.

Our research includes studying the principles and practical methods and materials involved in repair and restoration, particularly the use of adhesives and resins for the restoration of losses.  We also study the construction and materials used for complex, multi-media, or assembled objects, such as the Blaschka glass models. 

Conservation works closely with the Scientific Research Department to better understand the technology and nature of glass as it pertains to its deterioration and preservation.  Some joint research has been undertaken, for example, in the study of crizzling or atmospheric deterioration of glass.
