SAWDUST BRIQUETTE CHARCOAL
“SAWDUST BRIQUETTE CHARCOAL” is charcoal bar of either hexagonal or square cross section with a center hole. Size and shape of charcoal are manufactured to the general requirement of each country. Generally, square charcoal is in great demand in Japan whereas most buyers in Korea generally accept the hexagonal shape.
Briquette, a compressed mass of charcoal or other flammable material, often in regular shape of a pillow, brick or even in bar form of either hexagonal or square shape (the most commonly available form of sawdust briquette charcoal).
The sawdust briquette charcoal is produced without binder/chemical in the binding process, thus eliminating any unpleasant odor during burning. The same had been a popular barbecue charcoal for the last few decades especially in Korea and Japan, indoor barbecue is done almost in all restaurants in Korea today.
To make black charcoal the wood is carbonized (partial burning with little air) at temperatures between 400 and 700 °C, then the kiln is sealed until the burning stops and the heat slowly dies away. Now see the surface of the charcoal is black.
Black charcoal is soft and retains the outer layer of the wood. It is also easy to ignite and burns hot enough that it was used as fuel for tea ceremony, and ordinary daily food cooking including industrial use during the former times.
Charcoals produced around the world are mostly soft black charcoal type.
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.
