You lost me when you called a mineral a chemical.

Sand is largely composed of silicon dioxide (SiO2), which is a chemical compound. Each grain of sand is a tiny crystal composed of atoms of silicon and oxygen bonded together. These grains are formed by geological processes over long periods. While "sand" is a term for particle size rather than composition, its main constituent, especially in quartz sand, is indeed a chemical substance.

I expected this kind of reply.

By your reasoning we can just call anything chemicals, as all physical matter are a mixture of chemical elements.

Words matter. Sand is not a chemical.

All matter is made of chemicals.

Yeah. That's what I said.

A mineral is a chemical.
