Binchotan charcoal is regarded as the purest and most effective type of activated charcoal and is revered for its purifying ability. These sticks are made from 100% ubame oak and are exactly as they were when removed from the ancient kilns in which they are made. The high temperatures firing and short cooling times done by dousing the new charcoal with ash result in beautiful, glass like branches of binchotan. When added to a carafe of water, the thousands of microscopic cavities left in the wood effortlessly remove unwanted toxins and impurities, while softening and improving water's taste. Completely natural, the sticks are great for the garden and can be broken up and disposed of in soil once they start to diminish in efficacy (about 3 months). Materials: Charcoal made from ubame oak Dimensions: Each bag includes an assortment of 4 charcoal pieces of roughly the same size, typically 5" long and 1" wide.
