Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz – a chemically inert and relatively hard mineral. SiO2 grades at a 7 out of 10 on Mohs hardness scale, making it.
If your play sand fails the sugar test it is most likely a 'manufactured sand' made by crushing rock and soil. When your sand has different grain sizes this is a great indicator that your sand will be coarse, dirty, dusty, and can be difficult to create sandcastles or molds. It is not the crystalline silica that is the concern of OHSA or.

Mason Sand. Mason sand is created in the same way as concrete sand but is crushed finer. It is also created at the quarry by crushing granite, gneiss, limestone or trap rock then washing it though screens to ensure the uniformity of the grains. It can be used in cement, particularly for projects like swimming pools and concrete paving stones.
What Is Frac Sand Frac sand is a high purity quartz sand with very durable and very round grains. It is a crush resistant material produced for use by the petroleum industry. It is used in the hydraulic fracturing process (known as fracking ) to produce petroleum fluids, such as oil, natural gas, and natural gas liquids from rock units that lack adequate pore space for these fluids to flow.
