The modern pencil can trace its origins all the way back to the scribes of ancient Rome. Scribes used a thin lead instrument called a stylus to leave light but easily readable marks on papyrus. This original lead writing instrument<\/a> is posited as one of the reasons why pencils are still often referred to as lead pencils, even though the cores are made of graphite. Another theory is that graphite was once thought of as a form of lead.\u00a0<\/span>\u00a0<\/span><\/p>

In 1564, a large deposit of graphite was found in Borrowdale, England. While the mineral was appreciated for leaving a much darker mark than lead, and being less messy than ink, it was so brittle that any writing with it required a holder. Initially graphite rods were wrapped in twine, but after a time inserting graphite rods into hollowed sticks or dowels became common practice. Thus, the modern pencil was born.<\/span>\u00a0<\/span><\/p>

Mass production of pencils was first started in Nuremberg, Germany in the year 1662, with the first major European pencil maker, Faber-Castell being established nearly a century later in 1761. Spurred on by the success of Faber-Castell, other pencil manufacturers, including Lyra and Staedtler, led to a thriving pencil industry throughout the 19<\/span>th<\/span> Century and the Industrial Revolution.<\/span>\u00a0<\/span><\/p>

Although there have been some changes to pencils over the years, such as going from a round form factor to hexagonal to stop them from rolling on desks, and materials other than wood being used for the casing, pencils have essentially remained unchanged for hundreds of years.<\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

A carbon pencil, also known as a charcoal pencil, is a drawing tool filled with compressed charcoal or carbon,<\/span> sometimes mixed with graphite,<\/span> encased in a wooden or paper barrel. These pencils are popular among artists for creating rich, expressive, and dramatic drawings and sketches. They are especially useful for shading, producing deep contrasts, and achieving a wide range of tones.<\/span><\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

A carpenter’s pencil is a specialized marking tool used primarily in woodworking and construction. It typically has a rectangular or elliptical shape, which prevents it from rolling off surfaces and makes it easy to grip. Carpenter’s pencils are designed for marking lines and measurements on wood.<\/span><\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

A solid pencil, commonly referred to as a “solid graphite pencil,” is a drawing and writing tool made entirely of graphite with no wooden or plastic casing. Solid pencils are used for sketching, shading, and technical drawing, and they allow for precise and versatile mark-making. The artist or user holds the exposed graphite and can manipulate it to achieve various line widths and tones.<\/span><\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

A watercolour pencil<\/a> is a versatile drawing tool with a water-soluble pigment core encased in a wooden or plastic barrel. These pencils are used by artists to create both dry and wet artistic effects. When applied dry, they work like traditional coloured pencils, and when water is added, they can be blended and transformed into <\/span>watercolour<\/span>-like paintings, making them ideal for fine art, sketching, and detailed illustrations.<\/span><\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The H and B on a pencil refer to \u201cHard\u201d and \u201cBlack\u201d respectively. Using these two letters and the numbers two through nine, pencils are divided into 20 separate HB ratings, with 9H being the hardest and lightest and 9B being the softest and darkest. In addition to the H and B pencils, there is also an F category. F pencils fit in the middle of the scale and are specially made to sharpen to a fine point.<\/span>\u00a0<\/span><\/p>

Most pencils outside of the middle of the scale \u2013 HB, B, H and F – are typically viewed as art pencils, as the different hardness and blackness levels allow for shading, smearing and blending.<\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

One of the key benefits of writing or drawing with pencil is the ability to erase marks. The Roman scribes used wax tablets or pieces of pumice sandstone to scour marks off papyrus, and bread was commonly used to erase early graphite pencil writing.\u00a0<\/span>\u00a0<\/span><\/p>

The first rubber eraser was produced in 1770 by English engineer, Edward Nairne. This original eraser was not hugely effective, thanks to natural rubber extract being brittle and smelly. In 1839, when Charles Goodyear invented the process of vulcanising rubber, erasers were made durable, scent-free and as a result quickly became a household staple. Originally known as \u201cIndia Gum\u201d, rubber actually got its name from the use of the material to rub away pencil marks.<\/span>\u00a0<\/span><\/p>

Rubber pencil erasers don\u2019t just work through friction by scouring the graphite off the page \u2013 there is also a chemical element to the process. Graphite pencils work by leaving tiny particles of graphite in the fibres of paper. The eraser is essentially \u201cstickier\u201d than the paper<\/a>, so the graphite particles adhere to the rubber rather than the paper, erasing the mark.<\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t
