Creating microclimates: the solution for the conservation of sensitive materials in museums

The creation of specialized local microclimates is a technique used in museums to protect certain materials from humidity and other environmental agents that could cause damage. Humidity is one of the main factors that can affect the integrity of art objects and other materials displayed or stored in museums. To control humidity to desirable levels, many museums use moisture-absorbing agents, such as pre-packaged, sealed packets of gel or silica gel.

These wetting agents are able to control the relative humidity in a given environment and create a more suitable localized microclimate for the conservation of certain materials. They are especially useful for materials that are particularly sensitive to moisture, such as paper, fabrics, metals, and leather. By creating a localized microclimate with a damping agent, museums can reduce the need to air-condition the entire environment, which can be costly and often unnecessary.

The multi-level storage technique, combined with the creation of specialized local microclimates, is an effective approach to protecting materials in museums. Creating layers of protection, such as packaging in protective barrier wrap, placing in boxes or sealed storage envelopes, and organizing in appropriate cabinets and shelves, can help reduce exposure of materials to harmful environmental agents.

However, it is important to note that moisture absorbing agents must be used carefully and monitored regularly to avoid over-wetting or over-drying the materials. In addition, the choice of the type of moisture-absorbing agent and its required amount should be determined on a case-by-case basis, taking into account the properties of the material and the environmental conditions of the storage place.

In summary, the creation of specialized local microclimates with moisture absorbing agents is an effective technique for protecting moisture sensitive materials in museums. This technique, combined with the multi-tier storage approach, can ensure long-term preservation of materials.

However, it is important to remember that the choice of moisture absorbing agent and the amount required must be determined on a case-by-case basis, and materials must be regularly monitored to ensure they are adequately protected.
