White Sand
The silver-sand is a white sand, and results from the disintegration of soft, pure, siliceous sandstone. Beach-sand in some localities is also a white sand, but not so pure as silver-sand, as it invariably contains more or less of other substances, besides being somewhat calcareous from the presence of carbonate of lime, rendering it inferior to silver-sand in refractoriness. See SAND; FACING-SAND; CORE-SAND.
