Apr 11, 2015 As stated, Sand is composed of Quartz, among other things. The percentage of Quartz in sand differs greatly. On average, quartz makes up about 70% of sand. Quartz is a crystalline form of Silicon Dioxide. However, sand is not good to use in chemical experiments. First, because it is only 70% quartz (has a lot if impurities)
