[Black Silica (Graphite Quartzite)]
Black Silica is a mineral formed by the mixture of graphite and quartzite, and it is a highly rare mineral found only in the upper reaches of the Amagawa River in the Shinmei district of Kaminokuni Town, Hokkaido, the only place in the world.

Recently, high-quality Black Silica has become difficult to obtain, but we have acquired a good quality batch.

When added to a bath, it provides a warming effect, and adding Terahertz further enhances the hot spring experience.
Adding 2kg is ideal.
You can also break it down to make silica water, so please feel free to ask questions after your purchase.

There is also Black Silica for agricultural fertilizer, which may be oxidized. Therefore, even if you already have Black Silica, please do not mix it and use it separately.
