About Silica : Silica is a compound that is found in many different types of rocks. It is also found in sand and soil, as well as in glass and ceramics. Silica is one of the most abundant elements on Earth, making up 45% of the Earth's crust. It is also the second most abundant mineral in the human body (calcium is the first).
