Analysis Of Crystals In Bubbles In Glass

Analysis of gases in bubbles neglects the important possibility that a gaseous species causing the bubble at molten glass temperatures maybe solid at room temperature. Analysis is not complete unless the bubble is examined for solid deposits. In the method developed, the crystals are removed from the bubble in a fluid plastic and transported to a suitable substrate. Optical microscopy, electron probe microanalysis, x-ray diffraction and electron diffraction have been used to analyse particles of diameters as small as 0.05 um.
