Agents of Deterioration and YOU: Preserving Household Treasures
The collections at the Science Museum of Minnesota are very diverse any way you look at them. There are 1.75 million objects ranging from dinosaurs to butterflies, canoes to Pre-Colombian ceramics. In the Conservation Department, we are most likely to approach objects from a materials viewpoint. We study the material (i.e. stone, glass, hide, wood, etc.) from which an object is made. With human-made artifacts, we also study how the object is made. By understanding the material or materials of which an object is made, we can plan how best to store and display it and make informed decisions on its preservation.
Everything falls apart eventually. In the field of Conservation, we try to prevent this eventual deterioration. The Canadian Conservation Institute (CCI) has recognized nine agents that lead to the deterioration of materials. In the poster "Framework for Preservation of Museum Collections," CCI outlines the nine agents, acute and long term results of damage, and methods for preventing damage.
The agents are:
