FAQs

What is Black charcoal?

Black charcoal is a type of charcoal that is produced from carbon-rich materials such as wood, coconut shells, or bamboo. It is made by heating these materials to a high temperature in an oxygen-free environment, a process known as pyrolysis. The resulting charcoal is black in color and has a porous structure, which makes it useful for a variety of applications. 

What is white charcoal?

White charcoal, also known as Binchotan, is a type of charcoal that is traditionally made in Japan from oak branches or other hardwoods such as chestnut, cherry, or maple. White charcoal is made by pyrolyzing wood in a kiln at approximately 240 °C for 120 hours, then raising the temperature to around 1000 °C. Once carbonized, the material is taken out and covered in a damp mixture of earth, sand and ash.

What is hardwood charcoal?

Hardwood charcoal is a type of charcoal that is made by slowly burning pieces of wood in the absence of oxygen until all the natural chemicals, sap, and moisture get out of the wood, such as garden hardwood, plantation wood, acacia wood, eucalyptus wood.

What is softwood charcoal?

Softwood charcoal is a type of charcoal made from the wood of industrial, short-term trees  such as coffee, khaya, and eucalyptus which are abundant in the central highlands in Vietnam. Softwood charcoal is typically produced through a process of carbonization, where wood is heated in the absence of oxygen to remove moisture, volatile compounds, and impurities, leaving behind carbon-rich charcoal.

What is sawdust charcoal?

Sawdust charcoal, also known as sawdust briquette charcoal, is a type of charcoal made from sawdust and other wood waste materials such as bark, branches, and twigs. Sawdust charcoal is produced by compressing these materials under high pressure and heating them in an oxygen-free environment until they are carbonized.
