The objects conservation laboratory was built in 1991 in an area adjoining the paintings conservation laboratory. The lab is equipped with a fume hood, a deionized water system, portable fume extractors, daylight adjusted lighting, built-in cabinetry, powder-coated cabinets for storage of objects, an area for photo-documentation of three-dimensional objects, and a surgical binocular microscope.

In the objects laboratory, the conservator treats and maintains objects from the permanent collection, including furniture, sculpture, painted objects, metal objects, architectural models and fragments, glass, ceramics, plaster, and organics such as ivory and plastic objects. Objects from both Carnegie Museum of Art and The Andy Warhol Museum are cared for in this laboratory.
