Rocks and minerals break down over time into finely ground granules. These particles are Silica Sand.

They can be as big as a gravel and as small as a silt, ranging from 1/16th of a 1 mm to 2 mm in diameter. 

Composed primarily of silicon dioxide (SiO₂) makes it one of the most abundant and versatile sands found in nature.
With careful harvesting, It is processed to enhance its smooth texture and consistent grain size.

This natural strength and durability makes it an essential ingredient.
