Black Silica has the characteristic of widely emitting far-infrared rays even at room temperature. For this reason, it is said to have health benefits such as alleviating coldness and stiff shoulders, promoting perspiration, and activating circulation, and is used in hot spring inns and bedrock baths. A chemical analysis of an arbitrary bead of a different size confirmed that silicon dioxide (SiO2), the main component of Black Silica, was present at 76%.
