Note on the Use of a Fluorescence Test for the Identification of Striae and Cords
JSGT 1939 V23 T073-T075
A fluorescence test is described for the identification of aluminous and siliceous cords in glass. In the test alumina-rich cords give a yellow fluorescence, but silica-rich cords do not affect the grey fluorescence given by glass in ultra-violet light.
