Silica dust is only harmful when it's inhaled deep into the lungs, where oxygen is transitioned into the blood. Silica can be found in sand but sitting on a sandy beach will not cause any respiratory harm because any sand particles breathed in will generally be too big to go beyond the nose or upper airways. It is the very fine airborne ...

Very finely powdered Crystalline Silica sand is used to manufacture glass, which means that glass making is a hazardous process. However, when the Crystalline Silica crystals are melted, they change form to Amorphous Silica (Non-Crystalline Silica). When this melted mass of Amorphous Silica is rapidly cooled, glass is formed.
