The Edgar Degas wing of the NGA houses nearly 50 original wax and mixed-media sculptures by Degas, including the most well-known of his sculptures, "Little Dancer, Aged Fourteen."
These sculptures, which are made from a mixture of beeswax and modeling clay, are off gassing and decaying their bronze casting - deteriorating from the inside out.
Purafil's CCCs, a passive monitoring technology, are housed within the cases housing Degas' sculptures to determine the concentration and types of gases originating from the sculpture material. Purafil's OnGuard 2000 Atmospheric Corrosion Monitors are used within the wing to continually measure the real-time effects of corrosion, as well as temperature, relative humidity, and differential room pressure.
Once a thorough assessment has been completed, Purafil will be able to identify the problem gases and establish a solution to remove those gases from the air.
