T. Mikouchi (FEGSEM): He examined a potted butt which contains two grains exposed on the surface. One of them is a mostly silica-rich amorphous phase possibly contaminated with aerogel. The other grain (2.5 x 1.5 microns) is made of a K-rich phase, probably a K-feldspar. Neither Ca nor Na was detected. It contains only Si, Al and K. Tried EBSD for this grain, but could not obtain diffraction.
