The Sketching Pencil and Graphite

The Sketching Pencil and Graphite

Can you imagine life without a pencil?

Even though we are living in the digital age, a lot of us still use pencils in our daily lives. We all like a good list! Maybe a quick sketch, diagram or a message on a post-it-note. As children, our first written word would have been with a pencil before we progressed onto an ink pen. Professionals like architects, illustrators, artists, urban sketchers, designers and the literary community may use a pencil much more frequently than the everyday person (Roald Dahl was believed to have written all his books using pencil). There is a pencil for every need and requirement from very hard to incredibly soft, from the lightest grey to the blackest black! There are mechanical pencils, white pencils, charcoal pencils, watercolour graphite pencils, carbon pencils and so on. In this article we will look at what a pencil is made from, how it is made and explain what the pencil symbols mean. We will then look at the different types of pencils available on the market to add to your essential tool kit of drawing supplies.

 

What is graphite?

Graphite is a mineral that is naturally occurring. It is a homogeneous solid with a definite chemical composition consisting of a form of carbon. Graphite is formed by extreme pressure and extreme heat in the earth's crust and upper mantle. Graphite and diamond actually share the same composition but have very different structures.

It can be found in large veins in older crystalline rocks and is mined extensively in China, India, Brazil, North Korea and Canada. However one of the largest deposits of graphite was found in the early 1500s in Cumbria England, it consisted of the purest and most solid graphite ever found!

Origins of graphite in drawing supplies

The pencil that you hold in your hand does not contain lead! This is a misconception. It is actually graphite, also known as plumbago or black lead. Historically, lead poisoning came from the lead paint on the pencil rather than the lead inside.

Graphite may be the oldest and the most historical mineral you have ever touched, yet we take this small detail for granted. Knowing your pencil has origins in the ancient world is incredible especially when you realise how it is still relative in this one. Originally sticks of graphite were used for writing, then during the late 1500 the graphite rods were placed inside wood sleeves that were glued together, very much like our pencils today.

The next evolution of the pencil was in 1790, clay was mixed with powdered graphite before firing it in a kiln, altering the softness of the graphite and the colour. The more clay added to the powdered graphite, the harder the lead becomes. 

Creating modern day graphite pencils

Today, to produce a modern pencil, there are as much as 14 steps or processes that need to be completed before the final product is created. Mixing powdered graphite with powdered clay to the correct properties is the first step. Then the soft graphite is extruded through a nozzle to form long strands of graphite much like watching spaghetti being made. When these strands are cut to the correct length they are dried in rotating perforated tins at temperatures as much as 1500°. Once dry, the leads are immersed in a bath of liquid wax. This wax is absorbed into the lead sticks. This process provides the graphite with a smoother finish when writing on paper. Grooves are milled into two slats of wood then the graphite is glued into place. The second slat of wood completes the graphite sandwich and then the wooden and graphite sandwich is dried under pressure for about an hour. The wooden graphite sandwiches are then cut into pencil lengths. Milling the pencils at this next stage will provide their shape, either round, hexagonal or a triangular shape. Pencils are then painted, stamped with the necessary information and branding then their ends are dipped. Once dried they are sharpened, and before being  packaged they have to pass through quality control! That's all there is to it! 

Fun Facts about drawing pencils

  • The reason why carpenter's pencils are various shapes such as oval, rectangular or octagonal, is to prevent them from rolling away whilst working.
  • Erasers were not put on the ends of pencils until 1858.
  • It has been estimated that the average pencil has enough graphite to write about 45,000 words!
  • Faber-Castell is the world's largest pencil manufacturer with over 260 years of history and experience.
  • Faber-Castell produces over 2.3 billion pencils a year.
  • On average a pencil can be sharpened 17 times.
  • An average pencil can draw a line 35 miles long.
  • Over half of the world's pencils come from China, with factories turning out 10 billion pencils, which is enough to circle the earth more than 40 times.
  • An average sized tree will make approximately 300,000 pencils.

Let's look at the classification of graphite and explain the different lead grades.

Graphite pencils are classified as either;

  • Soft Black - B 
  • Hard - H
  • Hard Black (which means medium hard) - HB
  • Firm - F  

All the numbers in between signify how hard or how soft the graphite is.

As more clay is added to the mixture of graphite, the harder the pencil becomes. The harder the pencil, the higher the number. H, 2H, 3H, 4H, 5H, 6H, 7H, 8H, with 9H being the hardest. Hard lead makes a light grey opaque mark.

The more graphite contained in the pencil, the softer and darker the pencil is and the higher the number. B, 2B, 3B, 4B, 5B, 6B, 7B, 8B. 9B. The softest graphite makes the darkest opaque mark.

When used on sketch pads, graphite leaves a soft shiny grey or nearly black mark depending on the degree of hardness. Rough or textured paper surfaces will allow the soft graphite to adhere better, whilst the smooth paper surfaces will allow for precision drafting using the harder pencils. The softer pencils leave a little dust, however the harder ones leave much less on the surface of the paper. Graphite will adhere to many surfaces like wood, all kinds of paper, some fabric, cardboard, mdf, anything with a slight tooth will work better. 

Usually the hardness or softness of a pencil is printed on the side with a letter on its own or with a number. See classification chart below:-

 

8B

Extra soft and very deep black, for drawing of an atmospheric or organic nature, used for high chiaroscuro effects or dark silhouettes. Great for creating form in figure drawings. Excellent for expressive shading and 3d rendering. Great for quick motion drawings.

Pencils, Graphite Sticks and Blocks for every occasion

When working with graphite it is essential to find the right pencil softness or hardness for the project you are working on. Graphite is an incredibly versatile material to work with, with endless possibilities for creating different finishes; metallic lustre or matt black textures and marks. Once applied to paper, graphite can be erased, smudged, smoothed, buffed, can be used to create an ultra fine line, blackest black line, crushed to make dust or pushed into the substrate with a cloth, tortillion or your fingertips. Koh-I-Noor even makes graphite dust for those large atmospheric areas which need blending or add a little water to create washes of texture.

Similar to charcoal, graphite can be manipulated to create many different outcomes. And the same graphite pencil has endless possibilities just by altering the pressure you apply or by altering  the angle you hold your pencil. 

When buying drawing pencils there are many sets on the market to choose from, buying a set can be incredibly useful as most of them come in handy protective tins or boxes and contain a combination of soft and hard pencil grades.  We have listed some here to help you choose the right one for your project.

Clutch and Mechanical Pencils 

Clutch/mechanical pencils


A clutch or mechanical pencil is basically a plastic lead holder with a separate solid graphite replaceable lead inside. The mechanism on some of the pencils clutches the lead inside hence the name and will release the lead so you can set the length yourself and some mechanical pencils once pushed down will only release a certain length incrementally. There are many different types and styles to choose from.

They never need sharpening as the lead inside the case is pushed down to the point where it is worn away. Clutch and Mechanical pencils are used for technical drawings, and also by fine artists and illustrators and provide a constant neat fine line. Fine and meticulous detail can be achieved using these pencils. The replaceable leads come in the same grades as normal graphite pencils. Another great advantage of these pencils is they stay the same size in the hand so you can maintain stability and balance whilst working.

 

Koh-I-Noor Versatil 5311

Mechanical propelling pencil with lead diameter 5.6mm with a robust design and metal construction. The pencil's barrel features a profile with three longitudinal grooves for better pencil grip and a handy pocket clip.

Replacement leads can be inserted via the front of the pencil while the end cap is held down to hold the clamp open or can be dropped into the back of the pencil after unscrewing the end cap.

The 5311 comes ready loaded with a HB lead. Refills available in 2B, 4B and 6B

An Artists' Guide to Charcoal
An Artists' Guide to Charcoal

by Ellie Jakeman January 06, 2022 0 min read

Compressed charcoal was developed in the 20th century to strengthen the natural structural weakness of Willow and Vine charcoal. To create compressed charcoal or charcoal pencils natural gum or wax binder is added to powdered charcoal. This makes the charcoal stronger to draw with and produce less dust. Many grades of this compressed charcoal can be found in stick forms or in the form of charcoal pencils.
