It allows you to enjoy pure water while limiting your release of plastic materials into the environment and transforming tap water into mineralized water.

What is the history of Binchotan charcoal? The origins are not completely clear, but it is believed that a form of Binchotan charcoal (sometimes referred to as `` white charcoal '') was introduced to Japan by a Japanese monk and scholar called Kukai 1,200 years ago. . It was during the Edo period (17th century) that a man called Binchuya Chozaemon made it popular. How is it done? The sustainably sourced wood is placed in a kiln and charred at a relatively low temperature for a period of time, then towards the end of the process the kiln temperature is raised to around 1000 degrees Celsius to heat the wood red. The charcoal is then removed and quickly covered with a special powder made from earth, sand and ash, which gives the surface of the charcoal a whitish tint (explaining the name `` white charcoal ''). The rapid rise in temperature, followed by rapid cooling, incinerates the bark and leaves a smooth, hard surface. If you type it, you will hear a clear, metallic sound.
