Loess covers 10% of the earth’s surface and contains an abundant amount of calcium carbonate (CaCo3).
Due to this calcium carbonate, loess has a viscosity that makes it hard to scatter, and when water is added, it changes into clay.

It is composed of silica (SiO2), alumina (Al2O3), iron, magnesium (Mg), sodium (Na), and potassium (K) and these components and enzymes radiate a large amount of far infrared rays, and that is why loess is called a living form.

Structurally, it has a honeycomb structure with a large surface area, and the numerous spaces consist of an overlapped structure and the sponge-like holes contain a large amount of far infrared that is radiated when heated, and as a silicide mineral that stimulates molecular activities of other objects, it can be called a ‘storage of solar energy’.
