when you make charcoal do you have to burn it? how does it hold a flame after its already been burned once?

Answer 1

What making charcoal does is burn off the oils and tars in the wood leaving behind pretty much just carbon. (It boils the water out of the wood as well.)

In actual fact then, the charcoal is only partially burned. When the charcoal itself is burned, it is just completing the process.

Answer 2

The manufacture of charcoal from wood requires that you burn off, at a fairly low temperature, all the organic materials except the carbon itself. In other words, incomplete combustion. The carbon that is left can still burn, combining with O2 to produce both carbon monoxide and carbon dioxide. Since the monoxide is deadly poisonous, charcoal should never be burned indoors.

Answer 3

First a fire is built in a air tight burner loaded with wood and when it is all ignited the draft(air intake)is closed and the fire dies from loss of oxygen. Then the resulting unburned wood is carbonized and carbon is very inflammable even though very little smoke and flames are present.Charcoal is one of three ingredients in black powder used in old muzzle loader guns.

Answer 4

It's not completely burned the first time, It's charred. "Char-coal"
