Sandblasting Sand
Silica Sandblasting is a commonly used method of removing impurities from surfaces; this is because sand particles are almost the same size and the edges of the particles are sharp, hence making this type of grit efficient in abrasive blasting. Silica sand or silica quartz is still a more affordable sandblasting abrasive solution compare to other alternative mediums and with the right equipment and working environment you can never go wrong.
