what uses are there for the mineral Feldspar? | Yahoo Answers

 · The glass industry prefers to uses mainly orthoclase (potash feldspar) because it tends the melt to clear glass while albite (soda feldspar) tends the melt to a translucent glass. In the preparation of glazes the fine powder of feldspar is mixed with silica powder in a thin slurry.
