Moisture absorbing materials such as silica gel are commonly used within museum cabinetry to eliminate or reduce the fluctuation of relative humidity (RH) and to condition the enclosed space to a desired level of relative humidity. When silica gel is employed inside cabinetry, it is recommended that museum staff use systematic procedures and standardized containers. The gel can be conveniently contained in a standardized enclosure or container to assist in quantity control, facilitate maintenance and improve handling efficiency. Economical containers can easily be fabricated to suit the needs of most institution cabinetry and curatorial circumstances.
