Abstract of the Disclosure The present invention is directed to a method for synthesizing highly crystalline pollucite articles at temperatures not exceeding 1650°C. The method comprises two general steps: (a) a glass frit is prepared having a composition varying from approximately the stoichiometry of Cs2O-2SiO2 to approximately the stoichiometry of Cs2O.4SiO2 with, optionally, up to 5% A12O3; and (b) that glass frit is reacted at a temperature between about 1000°-1650°C with an A12O3-containing materi- al in sufficient amounts to yield a final product having a stoichiometry approximating that of pollucite.
