Dear All,
I am analyzing wood charcoal from ancient ceramic kiln, and have
noticed that some wood charcoal remains (although they looked
carbonized) were extremely hard. They were so hard that I could not
even break with sharp razor. When I managed to break them open, most
of them showed shiny sections that looked as if they were glazed. I
suspect this is probably related to the temperature of the kiln for
which the wood was used as fuel. I would greatly appreciate if
someone can explain whether kiln chamber temperature is related to
charcoal condition.
Best,
Minkoo
