THE EFFECTS OF FINGERPRINTS ON SILVER. Cheel, V., Northover, P., Salter, C., Stevens, D., Grime, G., & Jones, B. U S A.
abstract   bibtex   
Sweat deposited by human fingertips can corrode many polished metal surfaces. Sweat consists of salts of light metals, particularly chlorides, traces of heavy metals, and organic compounds, such as fatty acids and urea, in solution in water. The combination of chlorides and fatty acids are the source of the corrosion. This paper describes the monitoring and characterisation of fingerprints on fine and sterling silver using a combination of microscopies and microanalytical techniques. Particularly useful were optical metallography, high-resolution scanning electron microscopy with energy dispersive X-ray spectrometry and 3D visualisation, and compositional mapping using monomer ion beams and timeof-flight mass spectrometry. These techniques have charted the evolution of the fingerprints and have conclusively demonstrated the damage caused.
