  • Does your play sand contain crystalline silica or other

     · Yes most of our sands (and most sands sold in home improvement and big box stores) have crystalline silica in them because they contain quartz sand grains (which is the common name for crystalline silica). These are the same quartz grains found on 99.9 of the ocean lakes and stream beaches in the US.

  • What are the Uses of Sand Silica (with pictures)

    Most sand silica is made from broken down quartz crystals. Its high quartz content makes sand silica the perfect ingredient for glass. 50-65 percent of the mix used to create glass is comprised of quartz. This sand quartz is mixed with other materials to create glass products with differing clarity ranging from transparent to opaque.
