Long before plastic bottles and expensive filters, artisans in the Japanese region of Wakayama (originally known as Kishu), discovered the art of creating Binchotan – as well as all its many uses… First, as a way of cooking, and later as a means to fertilise soil, remove odours and, most importantly, purify their drinking water.
Today, just as it was hundreds of years ago, each stick of KURO-Bō Activated Charcoal is created in the very same way as the original Japanese Binchotan.
KURO-Bō Activated Charcoal is created by carefully harvesting high-quality hardwood, which is then baked by highly trained craftsmen in a special kiln – initially at low, and then later at extremely high temperatures of over 1000ºC. This process causes the wood to carbonise and activate, while also enlarging its pore structure to enable maximum toxin adsorption. After 7 – 14 days, the carbonised wood is removed from its kiln and covered with a mixture of earth, sand and ash, giving it a temporary whitish hue – as well as its other name of “white charcoal”. Once cooled, the activated charcoal is then carefully hand-cut in order to be used as a natural water filter, as well as in many other innovative ways.
