A sand used for making glass that primarily contains quartz. Glass sand may also have a natural mixture of other metallic oxides such as lime (calcium oxide) and an alkali. For example, the sand at Amarna in Egypt contained 19% calcium oxide and was used for making glass in the 14th century BCE. High quality deposits of sand glass are also found in southern Germany, and the U.S. (Virginia, Pennsylvania, Massachusetts, and Maryland).
