American colonists imported pencils from Europe until after the American Revolution. Benjamin Franklin advertised pencils for sale in his Pennsylvania Gazette in 1729, and George Washington used a three inches (7.5cm) pencil when he surveyed the Ohio Country in 1762. [26] [ bettersourceneeded] William Munroe, a cabinetmaker in Concord, Massachusetts, made the first American wood pencils in 1812. This was not the only pencil-making occurring in Concord. According to Henry Petroski, transcendentalist philosopher Henry David Thoreau discovered how to make a good pencil out of inferior graphite using clay as the binder; this invention was prompted by his father's pencil factory in Concord, which employed graphite found in New Hampshire in 1821 by Charles Dunbar. [7] Liquid graphite pencils are pencils that write like pens. The technology was first invented in 1955 by Scripto and Parker Pens. Scripto's liquid graphite formula came out about three months before Parker's liquid lead formula. To avoid a lengthy patent fight the two companies agreed to share their formulas.

The most common pencil casing is thin wood, usually hexagonal in section but sometimes cylindrical or triangular, permanently bonded to the core. Casings may be of other materials, such as plastic or paper. To use the pencil, the casing must be carved or peeled off to expose the working end of the core as a sharp point. Mechanical pencils have more elaborate casings which are not bonded to the core; instead, they support separate, mobile pigment cores that can be extended or retracted (usually through the casing's tip) as needed. These casings can be reloaded with new cores (usually graphite) as the previous ones are exhausted. One of the most common pencil types is the graphite pencil, which is a pencil made with wood or a similar soft material around a graphite core. These pencils are used in schools and hospitals, for promotions and so much more. These pencils previously had lead cores, but when lead was discovered to be a health hazard, graphite became the new standard. Some people will still refer to the core of a pencil as the ‘pencil lead’ even though the pencil uses graphite. Solid Graphite Pencils

As well as simply being distinctive, the colour may have been inspired by the Austro-Hungarian flag; it was also suggestive of the Orient at a time when the best-quality graphite came from Siberia. Other companies then copied the yellow colour so that their pencils would be associated with this high-quality brand, and chose brand names with explicit Oriental references, such as Mikado (renamed Mirado) [f] [g] and Mongol. [75] [h] B = Soft pencil - These are the most commonly used for drawing. They are a soft grade of pencil, which means they're fantastic for blending. The higher the number, the softer the pencil will be. For example, 2B will be a slightly soft pencil, whereas 8B will be extremely soft. You want soft pencils to be the bulk of your tool collection. The first appearance of graphite encased in wood dates from around 1565, close to the time natural graphite was first discovered in Cumbria. Other natural sources exist in Siberia, Germany and in the USA. However graphite is now artificially produced by heating cokes (another carbon allotrope) at high temperatures. First, JD and I work in completely different ways. JD’s work is more planned and controlled, such as using frisket to blank out selected areas. That requires a very accurate initial drawing that probably cannot be readily altered during the drawing process. However, I love working in graphite because it offers that direct mind-to-hand-to-paper connection – you think, you draw. So I begin with a very loose set of guidelines (except where accuracy is vital) and I constantly alter or even ignore them as I draw each section. I also begin top left and work down to the bottom right-hand corner (as a generalisation). Nothing is blanked out. “A String of Memories” by JD Hillberry Eye liner pencils are used for make-up. Unlike traditional copying pencils, eyeliner pencils usually contain non-toxic dyes. [44] Erasable coloring

They are found in the same variety of hardnesses as compressed charcoal ranging from extra soft to hard, also referred to as 6B to HB.Joseph Dixon 1799–1869". Dixon Ticonderoga Company.

First, a little history: The Staedtler Mars Lumograph brand dates from 1931 and the lead’s slightly waxy composition was formulated for the creation of graphite drawings that could be printed from without the need for inking. Over time this formulation replaced the plain Mars leads.
