Pencil Hardness Grades and Their Use in Drawing

Pencils are an ideal drawing tool for sketches and drawings. However, not all pencils are the same. The wood-covered graphite pencil is bachelor in various degrees of hardness for different applications. In this commodity, you lot volition detect out virtually the dissimilar pencil hardness grades that are available, and for which applications most suitable for which hardness of pencils.

The Invention and Development of the Pencil

The Egyptians poured molten lead into bamboo or reeds about 5000 years ago and wrote with it. Just the pb was too solid and had other disadvantages, even though it was not known at that fourth dimension how harmful its constant use was to health. Nigh 500 years agone people switched to graphite, an chemical element of carbon, which is much softer than lead.

The abrasion caused blackness hands. So it didn't take long earlier the idea was born to encase the graphite rods in wood for better treatment. As the black material was so considered to be lead ore, pencils were given the name which has been used until today. From the 19th century until today, a mixture of graphite and dirt every bit well as various oils or greases for impregnation has been used to manufacture the pencil leads.

Why There Are Dissimilar Pencil Hardness Grades

Not all pencils are the same. From technical cartoon to writing to artistic sketches, you have the choice betwixt around twenty fine gradations in dissimilar degrees of hardness. This offers many advantages. Depending on what you desire to use the pencil for, you tin can cull the appropriate hardness. The mixing ratio betwixt graphite and clay in production determines how hard or soft the lead volition be.

Very hard leads only have a proportion of about 20 percent, and very soft leads contain upwardly to xc percentage graphite. The rut and elapsing of the burning process also determine the hardness of pencils. Extremely hard pencil leads have less abrasion. When sharpened well, they will get out very thin grey lines, which makes them ideal for detailed sketches.

Particularly soft pencils give you lot a broader, rich black line. They are primarily suitable for artistic purposes. However, the soft lead also wears out much faster and therefore has to be sharpened oftentimes. A pencil of medium hardness is best suited for writing. If you write on it, you tin quickly erase it over again with an eraser. Specially stenographers appreciate these advantages.

Pencil Hardness Chart and Their Applications

There is no worldwide unified standard for pencil hardness. This can be illustrated well with an instance: A pencil of hardness HB is of medium hardness in Europe, a soft pencil in Japan, and a pencil with a hard lead in the USA.
The 20 unlike degrees of hardness of pencils in Europe range from 9H for extremely hard to B9 for very soft. In the middle area, you will find the designations HB and F. The number after the messages H or B determines the respective degree of hardness within the ranges.

Pencil Hardness Chart

HB Scale	Pencil hardness	Use
H9 – H6	extremely hard	for lithography, cartography
H5 – H	difficult	for technical and graphic drawing and writing
HB – F	medium	for drawing and writing
B – B3	soft	for writing and freehand drawing
B4 – B6	soft	for artistic sketches and drafts
B7 – B9	very soft	for artistic designs and studies

Pencil Hardness Examination: Applying the Dissimilar Grades

No 1 who uses pencils for work, whether in a technical profession or in an creative profession, can manage with just 1 pencil hardness, only often uses the entire range. Cartoon with pencils requires some practice. If you have no experience at all, the medium hardness between H2 and B2 is recommended. You can describe shades of brightness from very calorie-free to dark grey. The more than pressure you lot put on the lead, the darker the strokes go.

Medium hardness grades are comparatively easy to use. They can exist sharpened well and also erased well. If you are inexperienced, a pencil that is too hard and used with too much pressure can quickly exit marks on the drawing paper in the grade of dents or even holes.

A too soft pencil lead has the disadvantage that it smears slightly when erased and the stain on the newspaper remains visible even when you pigment over information technology. The chafe is stronger with a soft atomic number 82. Care should exist taken when sharpening too as drawing considering soft pencil leads suspension off hands. You can change this by taking intendance not to use a sharpener with a blunt blade.

The Right Pressure for Different Pencil Hardness

If a fine and precise stroke is required, equally in graphic or technical pencil drawings, it is best to use the harder leads from H3 to H9. The stroke tone will be a lighter gray and volition go but slightly darker even with increased force per unit area. Every bit already mentioned, as well much pressure level volition just ruin the drawing newspaper.

For pencil images, use the soft pencil leads, with their thick, nearly black strokes which can create strong contrasts. The different hardness of pencils combined with watercolor painting is suitable for a mixed technique. The possibility to employ extremely fine strokes to the newspaper allows you to draw with great attention to detail. If, on the other paw, you lot want to brand an initial sketch of something, a pencil with soft lead glides more easily over the drawing paper. It is also ideal for shading and darker areas.

Effects with Cartoon Techniques and Materials

You can learn to describe with a pencil. Of form, this includes trying out many things but as well applying techniques that help you reach a specific effect. Hatching, i.e. drawing parallel lines, is a practiced beginner's practise. You tin can experiment past varying the density and direction of the lines.

If you lot like, you tin draw a pencil lead hardness nautical chart so you can run into at first glance how hard the lead tin exist used to achieve the desired artistic effect. It as well plays a function in how hard you press on the paper while drawing. The less y'all press on the newspaper, the softer the pb can be and vice versa.

If yous desire to depict a photo or something else, making a filigree will help you to reproduce the proportions exactly. Remember that yous will desire to erase the filigree later on yous have finished your pencil drawing, so you should apply the grid with a fine line without pressure. You can employ a simple brush to remove eraser residue. And then null can blur or smear.

Paper Structure as Some other Influence

The construction of the paper is also important for the desired result. The rule is to use a softer pencil for rougher drawing paper because on smoothen newspaper the chafe of the lead is lower. The paper quality also plays a role. Y'all tin can make kickoff sketches on simple newspaper, a precise pencil drawing requires a higher newspaper thickness.

The Pencil Quality

In add-on to the appropriate pencil hardness, quality is also a criterion if y'all desire to accept fun while drawing or sketching. Bad woods is more brittle, a bad varnish flakes off. Y'all volition notice this at the latest when sharpening the pencil. Refills of poor quality show irregular wear. Especially when drawing very fine lines, this is annoying.

Therefore, it is worth buying a higher quality pencil. A more expensive purchase here pays off due to its longer immovability. Nevertheless, proper handling of the material is also crucial for its durability. If a pencil falls down, even a hard lead breaks through. The hexagonal shape was developed to prevent the pencil from rolling off a tabular array, for instance. Only those who utilise the pencil constantly, like a stenographer, prefer a circular pencil.

In diverse pencil hardness tests, the Faber-Castell visitor has achieved first-class results with the Castell 9000 pencil in all degrees of pencil hardness. The renowned companies Stabilo, Lyra, Staedtler, Derwent, and Koh-i-Noor also consistently produce tiptop quality.

Pencils have many advantages over other writing and drawing instruments, of which their versatility is but one. They are very practical and inexpensive tools that you tin go anywhere. Another positive aspect is their ability to write in whatever position (e.g. lying on your back overhead) and at any temperature. And finally, you can immediately erase mistakes when writing or drawing with a pencil in the truest sense of the word. If you are interested in drawing, we would like to recommend our article on learning to describe very simply. We hope this artickle has helped to better understand the total pencil calibration.
