"Art & Earth." Art and Earth provide products made of 100% natural "Shirasu" (deposited volcanic ash and stones) collected from the vast Shirasu Plateau from Kagoshima prefecture to the south of Miyazaki prefecture, where Shirasu deposits with the maximum depth of 150 m. The Shirasu derived from a huge volcanic explosion 25,000 years ago has a very complicated structure with a countless number of bores opened on very fine particles. Silica, which is the main component of Shirasu, is an excellent "humidity adjustor" and alumina contained Shirasu is an adsorbent for odor or chemical molecules, giving Shirasu excellent "deodorant and disinfection properties." Therefore, Shirasu has been used mainly as wall material. Shirasu does not require grinding and high-temperature baking, thereby requiring no large energy consumption unlike diatom earth, and thus being an environmentally-friendly eco material. Art and Earth will develop and provide various Shirasu items trustfully usable at home as before, taking the advantage of the functionalities such as "deodorant, humidity control, thermal insulation, decomposition, and ionization properties" by utilizing the very complicated structure and the composition of Shirasu created from magma.
