WHITE CHARCOAL

White charcoal is made by carbonizing the wood at a moderately low temperature, then, near the end of the process, the kiln temperature is raised to approximately 1000 °C to make the wood red hot. When making white charcoal, you need to be quite skilled in removing the charcoals, which have turned deep red, from the kiln and quickly smother it with a covering of powder to cool it. The powder is a mixture of sand, earth, and ash. This will then give a whitish color to the surface of the charcoal. This is where the name “white charcoal” was derived. The quick rise in temperature, followed by quick cooling, burns up the outer layer of the wood leaving a smooth hardened surface. It is also called a “hard charcoal”.

As tested by the Charcoal Standard Specification Test by the Agricultural Ministry of Japan, white charcoal may take some more time to ignite, but its thermal conductivity is way better than ordinary black charcoal. The flame produced by white charcoal lasts long enough to be used as a fuel.

White charcoals are now used for industrial purposes like electronic components to medical applications in the scientific world.

Benefits of White Charcoal

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.

Recently, research shows that electromagnetic waves from electrical appliances like computer monitors and mobile phones gives harmful effect to the human body. Charcoal burned at high temperature seems to have a special structure that is good at electromagnetic waves absorption. The charcoal has to be processed at around 1000 °C to have this absorbing capability.

Once again, remember that black charcoal and white charcoal may look just the same charcoal, but it differs depending on how the fire is extinguished. They also differ in many chemical and physical properties such as carbon, oxygen, hydrogen, ash, hardness, and the calorific value and flammability.
