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. The HB Graphite Grading Scale". Pencils.com. Archived from the original on 21 March 2012 . Retrieved 14 March 2012.

Hi Peter, Derwent’s inktense outliner pencil is waterproof and I think it would work really well for you. wax-based drawing tools- like oil pastels or wax crayons- are waterproof and would act like a resist. They aren’t made from charcoal or graphite so they may not be exactly what you are after, but they could be worth experimenting with.

OTHER STUFF. Clay, wax, oil, other binders, etc. In general there seems to be a dry-to-oily spectrum, but some pencils (Primo, Ritmo, Pierre noire) seem to be described as offering smooth-but-dry writing, so that I’m left wondering if this is not a simple binary. Maybe smoothness-vs.-scratchniess is different from dry-vs.-oily. Fineness of blend would seem to be a factor. Pencils create marks by physical abrasion, leaving a trail of solid core material that adheres to a sheet of paper or other surface. They are distinct from pens, which dispense liquid or gel ink onto the marked surface. The Zebra Sharbo X CB8 is a pen that its user can personalize and define. With the Sharbo, you can customize the pen’s body color, pencil lead size, ink color, ballpoint or gel ink type, and tip size. The Sharbo X CB8 can hold one mechanical pencil component and two pen refill components that are sold separately. Reload the body by unscrewing the barrel and positioning the refill into any of the holders. To select a refill to use, simply twist the grip. Pen Hi Dlamini, I imagine charcoal will be cheaper to source as a raw material however it’s harder to handle during manufacture. If cheapness is your aim, it might be worth going for graphite as you often you can mix a filler or clay in with the graphite to make it harder or softer and to keep costs down. That being said I’m unsure of the import costs of materials into Swaziland. Thanks for the interesting replies so far. I’m still hoping someone will come in and masterfully clear up everything about what’s in some of these different 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] Some pencils can be confirmed to be oil-based: Pitt oil-base, Cretacolor Nero (manufacturer: “shiny…smudge proof…oil-based and therefore water-resistant”). It’s descriptions like “smudgy, just not dusty” that confuse me. Where to draw the line between not-dusty-not-smudgy and not-dusty-but-smudgy? One source says Pitt oil-base “semi-erases”: where does it actually fall on a spectrum? What’s less eraseable? Also called ‘woodless pencils’, these pencils are entirely made of graphite without the wooden exterior. These pencils are often used by artists for sketches and drawings. Because they have more writing surface area, they are excellent for shading in pencil drawings. Liquid Pencils Nicolas-Jacques Conte (namesake of the Conte brand) supposedly made the first modern pencil for Napoleon in 1795. This pencil is made by roasting clay, purified graphite and water in a kiln and then putting it is a wood sheath. Joseph Hardmuth, then improved the technique by discovering you could change the hardness of the pencil by varying the amount of clay used. Eagle Pencil Company applied for the trademark Mirado in 1947 (US Trademark 71515261). It is common belief that this was an attempt to disassociate the pencil brand from Japan, as one of the meanings of Mikado is emperor of Japan.

When you use graphite for your artwork, it develops a slight sheen so light reflects off of it. This becomes more prominent the softer the B grade. Historian Henry Petroski notes that while ever more efficient means of mass production of pencils has driven the replacement cost of a pencil down, before this people would continue to use even the stub of a pencil. For those who did not feel comfortable using a stub, pencil extenders were sold. These devices function something like a porte-crayon...the pencil stub can be inserted into the end of a shaft...Extenders were especially common among engineers and draftsmen, whose favorite pencils were priced dearly. The use of an extender also has the advantage that the pencil does not appreciably change its heft as it wears down." [30] Artists use extenders to maximize the use of their colored pencils.

F = Fine point pencil - This isn't a great pencil for drawing but can be used sparingly for minute detail, and fine grey lines. Numbers as designation were first used by Conté and later by John Thoreau, father of Henry David Thoreau, in the 19th century. [c]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.

They seem to have difficulty distinguishing their products. The pencils I am familiar with are basically the crayons in pencil form. Also known as non-photo blue pencils, the non-reproducing types make marks that are not reproducible by photocopiers [48] (examples include "Copy-not" by Sanford and "Mars Non-photo" by Staedtler) or by whiteprint copiers (such as "Mars Non-Print" by Staedtler).
