Water causes damage and results from natural occurrences, technological hazards, or mechanical failures. Many cases of water damage can be traced to accidents or neglect. "A great many of the materials that museum objects are made of are highly susceptible to contact with water and can be severely damaged by even brief contact, while others may be exposed to water for longer periods without harm.
Energy use increases with specificity - e.g. in will require more energy to maintain a quantity of air to a narrow temperature range (20-22 °C) than to a broad range (18-25 °C). In the past, conservation recommendations have often called for very tight, inflexible temperature and relative humidity set points.
In addition to repairing mounts, conservators worked on restoring the dioramas' set pieces and background paintings.
