Some people like Derwent pencils or the reformulated General’s line because they have the impression they mark more smoothly–is this a case of getting charcoal particles down to finer size and moving them in the direction of lampblack? However graphite is now artificially produced by heating cokes (another carbon allotrope) at high temperatures. In Southeast Asia, the wood Jelutong may be used to create pencils (though the use of this rainforest species is controversial). Willow charcoal tends to have a more uniformed, consistent mark and finer particles than vine charcoal. Shortly thereafter, a superior technique was discovered: two wooden halves were carved, a graphite stick inserted, and the halves then glued together—essentially the same method in use to this day.

The resulting strings are dipped in oil or molten wax, which seeps into the tiny holes of the material and allows for the smooth writing ability of the pencil. Charcoal is made by burning incompletely natural matter such as plants, wood or bone, over a long period of time in a chamber, pot or kiln that has restricted airflow.Charles Fraser-Smith During World War II, Fraser-Smith worked for the Ministry of Supply, fabricating equipment nicknamed "Q-devices" (after Q-ships) for SOE agents operating in occupied Europe. The use of an extender also has the advantage that the pencil does not appreciably change its heft as it wears down. Graphite is one of the most familiar inorganic, yet naturally occurring, materials that artists use, even though in its most common form, the pencil, it has only been used for the last 600 years. The Koh-i-Noor Hardtmuth pencil manufacturers claim to have first used the HB designations, with H standing for Hardtmuth, B for the company's location of Budějovice, and F for Franz Hardtmuth, who was responsible for technological improvements in pencil manufacture. Watersoluble graphite pencils and sticks are made using a water-soluble binder (like aquarelle pencils) which makes them easily activated with water (you’ll find that most graphite pencils are blendable with water- though not as easily).

One effect of this was that "during World War II rotary pencil sharpeners were outlawed in Britain because they wasted so much scarce lead and wood, and pencils had to be sharpened in the more conservative manner – with knives. Some people will still refer to the core of a pencil as the ‘pencil lead’ even though the pencil uses graphite.Charcoal is a dry medium that can be used in its raw form as sticks or powder, or mixed with gum or wax binder to make it easier to handle. If you would like to discover more about pencils check out our blog post ‘ Solving the Graphite Pencil Mystery: What Is Pencil Lead Made Of? The charcoal you’re using should say on the packaging what kind it is- it could be compressed charcoal with a relatively low binder density, or it could be thick willow charcoal, which is less fragile than vine charcoal. After marking the paper, artists then can create watercolour effects and blend colours together by using water on a paint brush to blur the markings made by the pencil.

The combination of charcoal and graphite pencils can enhance a drawing by playing both with tone and with the matte and reflective surfaces of each. Another celebrated pencil brand is Caran d'Ache, and it has one of the best fine tip pencils on the market, its Technograph Pencil.They erase reasonably well with a white, oval Factis eraser (Not completely) but not so well with a kneaded eraser. However, a classmate of mine was working with Faber Castell’s willow charcoal, and it produced a striking black. The usefulness of graphite for pencils was discovered as well, but graphite for pencils had to be smuggled. Paying attention to the different formats they come in, each products hardness and tone means you can often solve a problem you’ve been coming up with in your sketching and drawing by simply introducing a new form to your working collection, whether this is wet graphite powder to get a neutral tone as a ground, a carbon or charcoal pencil in a graphite drawing to get deep, rich dark tones, a hard graphite stick to add metallic details or the humble vine stick to outline your oil composition. Charcoal pencils are made by putting compressed charcoal (so charcoal powder and a gum or wax binder) into a wooden jacket or very occasionally into a paper jacket similarly to a grease pencil.
