A UNIT ANALYSIS OF FELDSPAR1

A method of feldspar analysis is described by which all the major oxides are determined on one sample, and a practical routine procedure is developed on the basis of this method.     

THE QUANTITATIVE MICROSCOPIC ANALYSIS OF COMMERCIAL FELDSPAR1

This investigation was undertaken to develop microscopic methods for determining quantitatively the mineral constituents in feldspars used in the ceramic and allied industries. After several methods had been tried, a method of counting the grains and of using liquids of different indices of refraction for distinguishing the constituents was finally adopted. Nineteen commercial feldspars were analyzed by this method and the results compared with the results obtained by computing the chemical analyses to mineral constituents. Another method in which a partially fused sample was examined microscopically was also found suitable. It is concluded that, while neither the counting method nor the fusion method is as accurate as chemical analysis, the counting method gives satisfactory results for plant control in terms of potash feldspar, plagioclase feldspar, and quartz when used by a skilled microscopist, and the fusion method gives satisfactory results in the hands of the plant technologist for estimating quartz.

THE BEHAVIOR OF FELDSPAR AND FLINT WITH ACIDS AND BASES1

On addition of acids and bases to fine-ground feldspar or flint, the same phenomena are observed as with clays, Le., flocculation, deflocculation, and absorption. The effects are less sharp than with clays, the zone of deflocculation covering a wider range of PH and flocculation occurring at lower pH (greater acidity). The sensitiveness of flint and feldspar to reagents increases with fineness of grinding.
