The quantitative analysis of glass by emission spectrography: a six element survey.
The use of emission spectrography for the analysis of small glass fragments (approximately 1 mg) is described. Levels of Al, Ba, Ca, Fe, Mg and Mn have been determined in approximately 200 samples, and with the exception of Ca their variation appears to be of value in the classification and/or discrimination of glass. The precision of the method has been studied and its accuracy determined by the analysis of standard glasses prepared in the laboratory.
