What is sand?
Show Hint
In ceramics, materials are often defined by their chemical role. Silica is a primary glass-former, Feldspar is a flux, and Grog is a temper (or opener). Sand is primarily used as a source of silica.

The Correct Option is A
Solution and Explanation
Step 1: Identify the primary chemical composition of sand.
Sand is a granular material composed of finely divided rock and mineral particles. Its most common constituent is silica (silicon dioxide, SiO₂).
Step 2: Compare this with the given options. "Fine Silica" is the most accurate chemical description. Flint is a specific form of microcrystalline quartz (which is silica). Grog is fired clay that has been ground up. Feldspar is a different mineral used as a flux in clay bodies and glazes.
