Cannel Coal
Cannel coal is a dull, bituminous coal. It is brittle
and has a slightly paler sheen than that of jet and
does not take such a high polish (Pedersen, 2003).
One way to tell the two apart is that cannel coal
has a black streak, and jet has a brown streak
(Pedersen, 2003).
The name “cannel” is believed to be a corruption of
the word “candle,” so named for its waxy nature
(Schumann, 2002).
