Unlike to commonly used writing pencils, graphite pencils are simply an art medium particularly designed drawing. These pencils are made with graphite that is also known as plumbago or black lead mixed with clay. They are usually rated by hardness and this means that the less graphite mixed with clay the harder the pencil it becomes and vice versa. Many popular artists across the world mostly use these type of drawing pencils.
Features of a Graphite Drawing Pencil
These pencils share techniques with some other drawing media. For instance, hatching, outlining, stippling, and crosshatching are some of the techniques used. The possibility of mixing media and a wide variety of leads extend the wide range of possibilities.
There are basically two systems of pencil-rating which include a European and US pencil-rating systems. The European system is based-on lettering and it’s the one used for artist’s pencils, while the US system is generally numerical. In the full range, there are about twenty ratings of graphite pencils for drawing, though several manufacturers provide sets with only a range of 18, or selected drawing pencils from within the full range. By typically varying the clay to graphite ratio, pencil manufacturers effectively adjust the hardness of the core, commonly identified by letters (HB, H, 2B, or F) or a number (2, 2-1/2 or 3).
Woodless graphite is simply a pencil-shaped tool for drawing only made of the clay mix/graphite, with just a thin paper-wrapper. Graphite drawing pencil comes in different variations in terms of hardness and color. Some available variations include HB, 2B, 4B, 6B, 8B, and 9B. A wrapper can be removed to offer a very nice, broad drawing surface. The colored graphite drawing pencils are used in two ways; when used while dry can give very subtle colors, but when used while wet, they give a more vivid color.
These types of drawing pencils also come with some accessories and among them is the pencil lengthener. This is a device used to slip onto one end of the pencil, thus making it easier for gripping and allowing the small tip to be used instead of throwing it away. Additionally, there are pencil caps to offer protection to the lead and pencil grips for decreasing writing fatigue. Sharpeners and erasers are also vital accessories that come with graphite pencils. Vinyl erasers are best known to be most effective when it comes to erasing a variety of graphite marks from a range of surfaces.
These features simply describe what graphite pencils are and what makes them most preferable and favorite among other type of pencils.
