Generally, iron content must be reduced to 0.030% Fe2O3 or less. &. Silica sand for making glass, pottery and ceramics must meet rigid specifications and generally standard washing schemes are inadequate for meeting these requirements. Sand for the glass industry must contain not more than 0.03% Fe2O3.
