First, raw bamboo is cut to about one-meter size and laid to dry for about three months. Then, the cuttings are heated in earthen kilns at 800 to 1,000 degrees Celsius for 28 days. Next, they are ground into a fine powder with microscopic pores in a mesh-like crystalline structure.When incorporated into soap, this micro-pore mesh of the carbon powder traps skin's organic impurities, which get washed away as you rinse.
