This is a graphite pencil made from black carbon (an old fashioned type of graphite, found in the hardwoods). One of the primary characteristics of coal (if not the most important) is that it is very difficult to obtain, so when you buy it from an old man in an abandoned coal mine, you may be in for a surprise, as he might know more about it than you do. There are also other dark types of graphite that are quite abundant in the woods and are considered to be a different species!
This graphite pencil can be produced very dark with only a handful of charcoal, charcoal dust, or charcoal powder particles. Since black carbon is quite common in the woods, many black carbon pencils will have a lighter color if there is more charcoal in the sample than would normally be there. A dark pencil can have a lighter grayish color once charcoal has been added. If there are many (but not many) charcoal or charcoal dust particles in the sample, it can still show off a dark graphite, even though it wasn’t intended to. Note the different color of charcoal and charcoal dust. The darker the charcoal particles, the darker the pencil.
The graphite in a black carbon pencil can look very dark or almost black with a variety of different colors, depending on the size of the charcoal or charcoal dust particles in the sample. A graphite colored pencil is probably most appealing to the pencil maker, as not only does it look professional, but it is not hard to make an impressive black carbon pencil; black carbon is a relatively high quality material. A black carbon pencil in the middle of a pencil is probably the most impressive black carbon they’ve ever made. If graphite in pencils is hard to come by, then this particular type of pencil could be very valuable. Graphite in a pencil is not as valuable as charcoal and charcoal dust, but there are still quite a number of good pencils made with black carbon.
