# Sand Silica Calculator

A white or colorless crystalline compound, SiO2, occurring abundantly as quartz, sand, flint, agate, and many other minerals and used to manufacture a wide variety of materials, especially glass and concrete is called as sand silica.
Sand and Silica
 Weight of insoluble ash: Weight of sample: Percentage of sand and silica =
Formula
Percentage of sand and silica = (weight of insoluble ash *100/weight of sample)
Silica Sandâ€”the most common ingredient in glass. Whether the glass is container glass, window glass,
Boro-silicate glass, fiberglass or water glass (sodium silicate), silica sand makes up approximately 60-70
Percent of the glass batch and therefore has a significant affect on the glass quality.

Example:
Calculate the percentage of sand and silica in ashes for the given details.
Weight of insoluble ash = 25
Weight of sample = 15

Solution:
Apply Formula:
Percentage of sand and silica = (weight of insoluble ash *100/weight of sample)

Percentage of sand and silica = 166.66666666
