Grain diameter 12mm (±0.5mm) Inner diameter 19cm *The photo shows a product with an inner diameter of 16.5cm. High-performance Hokutolite that exhibits higher negative ion levels than regular Hokutolite. Hokutolite is a natural monument in both Taiwan and Japan, and no new specimens are being mined. This product is made by firing powdered Hokutolite, which was mined in Taiwan before mining was banned, into ceramic (pottery). By mixing clay or other materials into the ceramic during the firing process, it's possible to add color. This new product successfully achieves an orange color by finely adjusting the powder's composition during the mixing process of the Hokutolite powder. High-performance Hokutolite (Taiwanese Hokutolite) exhibiting higher negative ion levels than regular Hokutolite. Hokutolite is a natural monument in both Taiwan and Japan, and no new specimens are produced. Therefore, this product is made by firing powdered Hokutolite into ceramic (pottery). By mixing in soil and other materials during the process, it can be colored. This product is a new product that has succeeded in producing an orange color by finely adjusting the components of the powder when mixing the Hokutolite powder. When the negative ion value is measured with an ion tester, it can be measured at more than double the value of the normal color.
