HEALING SHIGARAKI Oval freestanding ceramic bathtub

A meticulously designed bathtub that defies conventional pottery standards.‎ SHIGARAKI ceramic bath is burned with 99.‎999% purity germanium powders and radium powders as glaze.‎ It is made of Shigaraki local clay containing radium ore and no extra processing is done to maintain its original state.‎ Therefore, negative ion effects never become weaker and keep working semipermanently.‎ It was created as a large-scale piece using Shigaraki's coarse clay, which is highly fire-resistant.‎ Each ceramic bathtub is made using the reduction firing method and is resistant to shock and cold.‎ The glaze is carefully blended with high-quality Badgastein ore imported from Austria's Badgastein spa resort and fired.‎ It retains heat exceptionally well through far-infrared radiation, negative ions, and trace radiation hormesis.‎ In addition, the alpha rays emitted from the radium constantly vibrate, activating the water and giving it a smooth texture.‎  Further info from manufacturer on SHIGARAKI HEALING
