Comprising approximately 4% of the Earth's crust, calcium carbonate ($CaCO_3$) is a ubiquitous chemical compound that is the foundational material for many of nature's formations and an essential component in a vast array of industrial products. Its composition, however, is far more complex and fascinating than its simple formula suggests.

Millions of years ago, the evaporation of ancient seas left behind massive deposits of crystallized salt, a geological process responsible for creating the natural mineral we know as rock salt today. Also known as halite, rock salt is mined from these deep underground deposits across the world.
