Although early pencils were constructed in this manner, it is not how most wooden pencils are mass-produced today. Pencil lead is not lead at all; it's a combination of finely ground graphite and clay, mixed with water and pressed together at high temperatures into thin rods. We call it lead is because the Englishmen who first discovered graphite believed they had found lead. According to the Cumberland Pencil Museum , in the midth century, a violent storm knocked over several trees in Borrowdale, England, uncovering a large deposit of a black substance that was first thought to be lead.
More than years later, an English scientist discovered that the substance was not actually lead, but a type of carbon instead. The substance was named graphite, after the Greek word meaning "to write," since that's how people used the substance. Early pencils were crude versions of today's standard model. The first pencil was just a chunk of graphite used by carpenters and artisans to make markings without denting their materials.
This evolved into a graphite chunk wrapped in sheepskin, followed by a string-wrapped graphite pencil, the first pencil with a rod-shaped graphite core. To use one of these pencils, the writer would have to unravel the string as the graphite wore down.
A fine line is good, but wet is messy. About 2, years ago, the Greeks and the Romans realised that a sharpened lump of lead would mark papyrus with a dry light line.
A dry line is good, but light is hard to see. The beauty of the modern pencil is that it combines the best qualities of the paint brush and the lump of metal in one product. The modern pencil makes a line that is very useful because it is both dry so it doesn't run and dark so it's easy to see.
The modern "lead-free" lead pencil first appeared in the s, in Borrowdale, in the Cumberland Lakes District of England. The legend has it that a large tree blew over, and the local shepherds noticed a black material clinging to the roots. They tried to burn it, thinking that it was coal - but it would not burn. But they quickly found a use for it in marking their sheep. The shepherds had discovered graphite, which is actually a variety of carbon.
But at the time they thought it was just a variety of lead, so they called it Black Lead. We know that Black Lead was not commonly used in pencils by , because in that year, the Italian writing master, Giovanbattista Palatino, wrote a book describing what he thought would be "all the tools that a good scribe must have.
But 25 years later, in , Konrad Gesner, a Swiss naturalist and physician, wrote a book on fossils. In his book, he describes and makes a drawing of a new writing instrument that seems to be the first primitive Black Lead pencil. Lead pencils were now about to make their mark.
In , a character in Ben Jonson's play Epicoene describes some mathematical instruments including "his square, his compasses, his brass pens, and black-lead to draw maps.
