Abstract

Much of the effort of forensic scientists is directed towards establishing the possibility of a relationship between two or more items. The approaches vary, but generally, after a visual comparison, the items are subjected to several physical and chemical tests. In the case of paint samples, a visual examination will afford information as to the color [1], layer structure [2], thickness, pigment distribution, and so on. Subsequent tests could include pyrolysis gas chromatography [3] to establish the resin type and infrared spectroscopy [4,5] to examine both the paint vehicle and pigment. The visual examination of paint samples is one of the most valuable tests as it is easily and inexpensively carried out, affords high discrimination, and is nondestructive.
