What Type of Sand Is Used to Make Glass? Silica sand is the primary source of silicon dioxide that is essential in the manufacture of glass. To be suitable for producing glass, there must be a very high proportion of silica (above 95%) in the composition of the sand. That's why most sand deposits are not of sufficient purity for glassmaking.
