Silica Sand—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.
Calculate the percentage of sand and silica in ashes for the given details.
Weight of insoluble ash = 25
Weight of sample = 15
Percentage of sand and silica = 166.66666666
Percentage of sand and silica = (weight of insoluble ash *100/weight of sample)
