An improvement of the plagioclase glass fusion method

An improvement of the plagioclase glass fusion method
The Canadian Mineralogist (December 1966) 8, Part 5: 643-647


The need for a bored pit in the end of one of the electrodes of the arc welder as well as packing it with the sample or wrapping it in platinum foil is eliminated. Complete fusion of the entire sample is not necessary as the fragments of incomplete fusion can be identified and eliminated in determining the matching index of the plagioclase glass. Several minutes are required for fusion with the platinum-wrapped sample, compared to 1 to 2 seconds with an arc electro-welder. Preliminary results indicate an accuracy of + or -1 mole percent An.
