Statement

Samples were dried, then set in epoxy in a thin walled sample ring, polished and carbon coated. Two sessions of analysis took place using the JEOL JXA8530F Hyperprobe, with analyses on 13/10/2014 using a focused beam with no TDI. Analyses on 13/11/2014 used a 4 micron beam with TDI counting for 10 intervals over time period, see third tab in Excel file for beam setup. Approximately 10-15 glass shards were analysed per sample. Data were filtered to remove results that were obviously not glass.
