To Display or Not to Display
The exhibition of any artifact has inherent risks. Damage can be caused by light, vibrations, and fluctuation in heat and humidity. Care must be taken to design exhibitions which inform the public, without destroying the evidence of the past. A balanced approach which appreciates both needs and desires must be established.
The largest lead coffin is on exhibition at HSMC as an educational tool for the public.
Over time this artifacthas begun to show signs of object stress due to sheer weight, the softness of lead, and the corroded condition.
The case that houses the coffin had to be constructed out of inert, museum-quality materials, like glass, that do not off-gas or degrade. This dramatically decreases the rate of deterioration among archaeological collections. Many of the organic materials recovered from the coffins are very sensitive to fluctuations in relative humidity and exposure to ultraviolet radiations. The objects receive minimal handling and their cases are monitored for environmental changes with the aid of a hygrothermograph. Light is kept low, to avoid damage to pigments, and objects are regularly inspected for mold and signs of pest infestation. The exhibition of these artifacts is limited to three months.
