During the 's, no one knew the chemical nature of this material, as chemistry itself was still in its infancy. Since this writing material behaved similar to metallic lead, but had a darker color, people began calling it "black lead". Eventually, the name of the core of the pencil got shortened to "lead". In , German chemist K. Scheele finally determined pencil lead to be composed of pure carbon.
A decade later, A. Werner decided that this carbon material needed a new name and proposed the name "graphite" based on the Greek word "graphein" which means "to write". Black-core pencils currently contain and have always contained graphite, not lead. Carbon is the sixth element on the periodic table and is famous for forming the backbone of molecules found in fuels and in all living organisms.
Aside from biological molecules, carbon can also be found in nature in pure mineral form. Lord, Lewis J. January 22, , p. Sprout, Alison. June 15, , p. Urbanski, Al. November, , p. Toggle navigation. Made How Volume 1 Pencil Pencil. To make the wood casings for the pencils, square slats are formed, and then grooves are cut into the slats.
Next, graphite sticks are inserted into the grooves on one slat, and then a second slat with empty grooves is glued on top of the graphite-filled slot. Correctly sized pencils are cut out of the sandwich, and the eraser and metal ferrule are attached. Periodicals Leibson, Beth. Other articles you might like:.

I read this article and told the whole process of pencil making to my 4 childs. But im sorry you did not explained that which clays are mixed in graphite to make pencil. Childs are eager n anxious to know which clays in which propotionate mixed in graphite. I belive you will must do a kind favour to answer it by mail! Hans Koseck. A very thoroughly informative lecture.
I found only one mistake: the spelling of Quality. Tranise Dickson. Besides the written publications and periodicals listed, are there any pictorials or film clips about pencil manufacture? Thank you. Its a intersting process but i could not understand a composition of clay ,water,pigment.
Edward Cumming. You mention that Joseph Dixon, an American, in c. The excavation of the East Indiaman, Earl of Abergavenny, sank , has yielded a large number of both standard and sliding pencils. They were made as above and were made this way from or earlier. Made from Red Cedar the machining of the cedar for both the graphite groove and in the case of the sliding pencil, the dove-tail of the two halves is machining at its best. I would love to know how they did this. Some pencils are wrapped in decorative film with intricate designs, while others are screen printed or foil stamped with a logo or advertising message.
If they're not used as company giveaways, the pencils are simply imprinted with the brand name of the pencil manufacturer. The result is a beautiful pencil ready for sharpening! With a logo added, they also make great giveaways at school fundraisers, trade shows, and a variety of other events.

There are even some companies from the beginning that are still in business today, such as the General Pencil Company in Redwood City, California. The General Pencil Company has been owned and operated by the Weissenborn family since Fast forward over years later and the business is still in the family, with his great-great grandchildren helming the ship.
This company has a large part in the history of both pencils and America and continues to pave the way forward with their commitment to sustainability.
All their pencils are made from western-cedar wood found in California and Oregon as it's stronger and more eco-friendly. They also use recycled material in their packaging and send their sawdust waste to Duraflame, which converts it into logs for household fireplaces. Today, the General Pencil Company employs over 49 workers and owns 28 different patents for the pencil-making process.
All their products are made in the United States which gives them the means to meet demand, especially during back to school season.
Overall, there's no denying this manufacturer's role in producing the pencils we know and love today. Sampson Mordan and John Isaac Hawkins experimented with the first mechanical pencils over fifty years before the General Pencil Company opened their doors. However, they had an inferior design to regular wood pencils which stilted their popularity. Over patents were registered to improve the mechanical pencils design until it was perfected by Tokuji Hayakawa in Japan and Charles Keeran in America in the early s.
Mechanical pencils are divided into three categories: screw, clutch, or ratchet-based. In screw-based pencils, the lead slides down the barrel and is locked in place at the bottom. Clutch-based pencils are activated by pressing the eraser, which opens the jaws inside the tips and allows the lead to drop from the barrels.
Finally, ratchet-based pencils hold the lead in place with a few small jaws inside a ring at the tip. The jaws are controlled by a button that causes them to separate and allows the lead to come through. Today, ratchet-based are the most popular, though you can find all three at any retail store. Of course, other countries aside from America rely on good, old-fashioned pencils.
Take for instance Nigeria who made it a goal to produce their first ever homemade pencil by Although they've had their independence for over 55 years, this African nation hadn't been producing their own pencils, instead relying on imports from other countries.
They had everything they needed, including willing workers and rich resources, but they still hadn't been developing their own writing instruments. Nigeria's Minister of Science and Technology, Ogbonnaya Onu, is leading the pencil pack toward the future. Meanwhile, across the world in Denmark, the Viking Pencil Company produces pencils with knotholes; Faber-Castell in Germany uses softer woods like linden or basswood; Shahson's in Pakistan makes high-quality pencils for left-handed writers; and Blackwing in Japan uses a small amount of plastic in their graphite that makes their design less likely to smudge than others.
From the west to the east, we are all united by the love we have for high-quality pencils.
