Most charcoal is wood that has been carbonized by partial burning with little air. Generally, black charcoal is soft and retains the tree bark. On the contrary to regular charcoal, white charcoal is strong, white in color and has no dust at all. White charcoal is produced in a different and complex way then black charcoal. White charcoal is made by charring the wood at a relatively low temperature for some time, then, near the end of the process, raising the kiln temperature to about 1000ºC to make the wood red-hot. The charcoal is then pulled out and quickly smothered with a covering of powder to cool it. The powder is a moist mixture of earth, sand and ash, and gives a whitish hue to the charcoal surface. The rapid rise in temperature, followed by a rapid cooling, incinerates the bark and leaves a smooth, hard surface. White charcoal has several benefits. You can place it in a water container to filter water and release natural minerals. This will also help absorb chemicals in the pipe water. White charcoal also has the ability to warm the body and help improve blood circulation, skin, and hair when added to the bath. It also helps reduce blood pressure and cholesterol. White charcoal also supplies negative ions and purifies and balances the moisture content in the air. LavCal White Charcoal is made by traditional Japanese methods.
