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.Horticultural sand is a type of gritty, coarse sand, often known as sharp sand, coarse sand, or quartz sand. It is made from stones like crushed granite, sandstones, and, most importantly, quartz. When we talk about size, the sand particles can range from two to five mm in diameter, with the majority being on the larger end of the spectrum.
