Activated carbon is also called active charcoal, active coal or White Charcoal. It’s a form of carbon that has been processed to make it extremely porous – this is where its usefulness lies.

White Charcoal is black but its name comes from the unique way in which it is made and as point of difference to regular ‘Black Charcoal’. White Charcoal is made by charring wood at a relatively low temperature for several days then, near the end of the process, the kilns temperature is raised to a super-scorching 1000ºC.

The charcoal is pulled out of the kiln whist red hot and quickly smothered with a covering of powder to cool it. The powder is a moist mixture of earth, sand and ash, and it gives a temporary whitish hue to the charcoal surface – from which the material gets its name.

During the charring process there is a rapid rise in temperature, followed by a rapid cooling that incinerates bark and leaves behind a smooth, very compact, very hard surface. We often describe White Charcoal as having properties similar to porcelain; it will shatter and splinter rather than crumble and if you strike it you’ll hear a clear, metallic sound.

White Charcoal Use
Charcoal is best known as a fuel; across the globe, factories, households and BBQ’s rely on it to keep going.

Charcoal is familiar as a tool for drawing too – remember those childhood art classes where you’d get covered in the stuff.
Perhaps you know of its use as a dietary supplement for gastric problems (even the Red Colobus monkeys of Africa are clever enough to regularly eat charcoal, thereby solving their monkey indigestion).
Less obvious are the charcoal filters that are widely used but often hidden away inside vacuum cleaners, air filters or gasmasks. But here at Sort Of Coal we don’t produce any of these things – we are trying to find new, modern ways of using charcoal that take full advantage of its very special qualities.
