Statement

Grain-size data: Laser-diffraction using Malvern MasterSizer 2000 XRF: Analysed using the PANalytical Axios Advanced spectrometer at the University of Leicester. Major elements measured on glass beads fused from ignited powders; trace elements on pressed powder pellets. Results stated as component oxide weight percent and recalculated to include loss on ignition (LOI), which was separately determined. EPMA Glass compositional analyses: JEOL JXA-8600 wavelength-dispersive electron probe microanalyser (EPMA) at the Research Laboratory for Archaeology and the History of Art, University of Oxford; 15 kV accelerating voltage, 8 nA beam current, and 10 ?m beam diameter. EPMA Mineral compositional analyses: Cameca SX100 EPMA at the University of Bristol; 20 kV accelerating voltage, 20 nA beam current and 1 ?m spot size. Na analysed first; primary mineral standards used for calibration.
