Every museum goer has encountered warnings about touching artifacts, but have you ever wondered just how damaging that contact can be? I think we would all agree that leaping a barrier and picking up a vase is a definite bad idea, but what about resting your hand on a chair or poking a polar bear specimen? The truth is even the lightest touch can cause harm.
Last week I took a break from dry ice cleaning to work on the “Virginia Gun,” an IX-inch Dahlgren shell gun which sits at the entrance to the Ironclad Revolution exhibit. It was recovered along with the USS Merrimack by the Confederates and was used aboard the renamed CSS Virginia during the Battle of Hampton Roads (1862). It is a fascinating object that draws a crowd. Unfortunately, it also tends to draw wandering hands. My job was to remove greasy fingerprints from the side of the barrel. This got me thinking about how we protect objects and how although we have “do not touch” signs around the museum, visitors might not understand why this is such an important rule.
