Silica sand is commonly used as a mineral abrasive for industrial blasting. Though blasting with silica sand can create dangerous dust, exposure is easily avoided by following recommended PPE (personal protective equipment) guidelines and/or by coating the sand with solutions designed to control dust.
Silica quartz is often white or colourless, it can come in a wide range of shades. The colour of each sand deposit depends largely on the variety of minerals and rock detritus that make up the resource.
