How Different Materials Affect the Drawing Process

by Dan Gheno

There is no substitute for skill and experience. A quill pen did not draw Study of a Male Nude—Michelangelo
did. The identical pen and ink in the hands of a rookie would not produce a similar masterpiece. But it’s also true that if Michelangelo had used a ballpoint pen or a No. 2 pencil, the drawing would not possess the same depth of value or volume. The choice of materials is a vital part of how an artist approaches his or her work, and it’s critical to pick the right drawing instruments, surfaces and other tools to fit the needs of your artistic vision.

If there’s one thing I’ve learned over the years it’s that you shouldn’t try to make a material do something it can’t. Just as you can’t force a cat to bark or a dog to meow, it’s impossible to force your materials to do something against their essential nature. For instance, graphite, sanguine chalk and colored pencil all yield less contrast than compressed charcoal or ink, so if you’re interested in deep, divergent contrasts, you want charcoal rather than graphite. However, when the goal is a more delicate form of rendering, charcoal can work, but I personally prefer graphite or colored pencil, which I find more readily suited to this goal.

This article will chronicle the advantages and pitfalls of the drawing materials I’ve personally grown to know over my decades as an artist. We’ll examine the pros and cons of media including graphite, colored pencil, charcoal and ink, along with surfaces and other tools. We’ll discuss when to use them, when to avoid them and what you can expect (or not expect) from each medium.

Middle: vine charcoal. At bottom, from left to right: compressed charcoal, sharp single-edge razor blades; and two block erasers—one for colored media, another for dark media.

Graphite

If you discount the mural I drew with Crayola crayons at age 4 on the side of my older sister’s 1951 Chevrolet sedan, my first experiences in drawing were rendered with a yellow No. 2 pencil, a common first experience. Because of this early familiarity, graphite pencils remain the most comfortable and safe choice for many artists until they start taking art classes. Well-meaning teachers sometimes try to get their students to kick the graphite habit, forcing them to use charcoal instead. But I usually encourage novice students to work with what’s familiar to them at first. When trying to grasp such challenging issues as human proportions and value shapes, it doesn’t help to struggle with the technical problems of a new medium as well.

Known mostly as a linear medium, graphite is more flexible than many artists and teachers give it credit for. You can actually get some very fluid and painterly effects with it, for instance by applying powdered graphite to the paper with a brush or chamois. Graphite also comes in sticks of various shapes, sizes and hardness, which allow for a variety of delicately blended masses or broad, assertively expressive strokes.

The main drawback to graphite is its inability to achieve the intensity of darkness that you can get from compressed charcoal or paint. You can go only so dark with graphite before the material builds into a reflective sheen that actually looks lighter instead of darker. In fact, the more you try to rub and grind graphite into one area of the paper, the more you will burnish it into a dense, shiny mass, canceling out any sense of realistic value and atmosphere you have achieved elsewhere in the drawing.

I don’t often use graphite anymore, but when I do it’s usually for precise rendering or for analyzing complex shapes or anatomical forms on the body that I find confusing. Indeed, when graphite was first developed as an artistic medium by the English in the mid-1500s, it was promoted as an easier, more practical and more fluid alternative to metalpoint for detailed, analytical drawing. Graphite doesn’t drag on the paper as metalpoint does, so with graphite artists can apply value masses in a more natural, fluid manner. But one thing missing from graphite is metalpoint’s varied depth of line, which can seem to pulsate in a three-dimensional manner.

Colored Pencil

For me, colored pencil seems to combine the strengths of graphite and metalpoint. Some brands of colored pencils impart a similar delicacy and depth of line as metalpoint, and although colored pencils aren’t quite as erasable as graphite, brands such as Stabilo Original and Caran d’Ache have much of graphite’s potential for revision and sensitive ease of application.

Colored pencils are particularly suited to exacting linework. Many brands of colored pencil can be sharpened to pinpoint precision using a razorblade. I use a mid-value sanguine color for most of my colored pencil drawings, particularly when drawing on white paper. It allows for a delicate touch, but upon pressing harder I can get a darker, more assertive line. I will often use a darker sepia color when working on toned paper.

Colored pencils share graphite’s limited range of value contrast, but I find this can work to my advantage, forcing me to take my time to analyze the model’s light and dark patterns as I render them. I usually prefer to build up my values gradually, shading across large shadow shapes with succeeding sweeps of tone, until I reach the desired darkness. Working in successive layers can allow one to better maintain the weave of the paper and help to impart a sense of atmosphere.

Colored pencils can require a gentle touch. They are often fragile and prone to snapping in mid-stroke if you press too hard, leaving an unerasable skid mark on the paper. If you try to push your values too dark all at once, they will become dense and shiny. With certain colors the hue may even change with heavy pressure or when you let your pencil point get too short, allowing the wood casing to chafe your linework.

Chalk and Charcoal

Whether you’re using them in pencil, stick or powder form, pure black chalk and charcoal provide the greatest value contrasts. I often like to work with them in a loose manner, starting with a broad value mass that relates to the big, gestural shadow shape found on the model. Some artists prefer powdered charcoal for this initial stage, but I frequently begin my sketches in a faint, linear manner with vine charcoal because it’s so easily erased or adjusted. I then follow up with a more permanent compressed charcoal pencil or stick, which usually works as a sealant, holding the more ephemeral, easily smudged vine against the paper.

Charcoal pencils come in several grades of hardness, like graphite. Softer charcoal is often good for building up masses on large, expressive drawings, whereas harder compressed charcoal or carbon pencils, such as H and HB, are more suited to line work on a smaller scale. Hard charcoal pencils, which are easy to sharpen to long, sharp points, can be used to quickly render thick and thin lines by varying the position of your hand, and you can build toward your dark value masses with a rapid weaving of strokes. Broad, lineless tones are possible as well. Holding the pencil to the side, you can glide the long portion of the charcoal shaft across the page, gradually building up the tone into a broad value mass, much as you would when using a colored pencil.

You might notice that vine charcoal tends to be a bit warmer than compressed charcoal. When using both, I often need to go back into my drawing at the end, sweeping over my value masses with one or the other to harmonize between cool and warm. For the same reasons, it’s not a good idea to mix white pencil or chalk with black charcoal (or graphite), unless you do so systematically throughout the drawing. Otherwise, the mixed-up results will look cloudy or just plain chaotic, especially on toned paper.

Tip: When working in compressed charcoal or in graphite, keep to a limited range of pencil hardness to maintain evenness and texture harmony in your toning. Jumping between divergent grades—for instance from an HB to a much softer 6B—can result in a distracting cacophony of rough and smooth textures.

Crayon

Perhaps it was the sense of shame I felt for drawing on my sister’s car—and the adverse conditioning that came from the hours of elbow grease I spent rubbing out my scribbles—but it was a long time before I renewed my interest in grease- or oil-based drawing instruments. When I did, using a variety of brands from Cretacolor to Faber-Castell’s Pitt, I found the medium offers a handy compromise between the darkness achievable with softer chalks and pastels and the smoothness of colored pencil and graphite. When drawing with crayon I generally use a sanguine color.

I’d recommend not combining different brands of crayon in one drawing. Hues differ greatly between manufacturers, even if they have the same name.

Ink and Ballpoint

Over the years I’ve worked with a variety of inking tools, including brushes, dip pens, fountain pens, ballpoint pens and Rapidograph pens.

During the 1970s, when I did drawings such as Woman Seated, Looking Away, my favorite way to work was by using a fountain pen to render the lines and a felt brush marker to wash in the big value masses. I normally dipped my “fountain” pen into a bottle of ink so that I could use a dark, heavy ink that would otherwise clog up the pen. I used an italic point held sideways, which offered a delicate fine line and provided thick-thin variation. I also used a grinding stone to sharpen and reshape my pen points to get extra fine lines. Water-based felt brushes, such as the one I used to lay in masses in this drawing, wear out quickly. Instead of throwing them away I open their tops and fill them with watered-down ink to rejuvenate their wells. I often prefer the more watery effect of these recharged brushes to the results I get with a new one.

Although I still work in this technique on occasion, today when I work in ink I usually use ballpoint pens, most often for eye-hand coordination exercises. Because ink is irrevocable, it’s a great training tool, reinforcing the habit of thinking before you put down a line.

I was first attracted to ballpoint pens for their ability to replicate fine, etch-like lines. Over the years, however, manufacturing standards have diminished, and today many brands of ballpoint spurt out unexpected blobs of ink—usually at the worst possible moment. I recommend you experiment to find the best and most consistent brands. (I’m a fan of the Pilot EasyTouch .7mm fine pen and its refill catridges, which can even be used on their own.) In all cases, you’ll need to get in the habit of regularly cleaning off the paper detritus that builds up around the pen point, which can produce splotching after only a few minutes of work.

I find it helpful to locate the beginning and end points of the objects I’m drawing in ink. For instance, when drawing a hand on the hip, I might place dots at the shoulder, elbow and hip and then draw in between these points. If you don’t put placeholder points for all the major beginning and end points or at least try to imagine them in your mind, it’s easy to underestimate any foreshortening and draw a line too long. And with ink, of course, there’s no erasing your mistakes.

Mixing Media

There’s no need to confine yourself to one medium. Don’t be afraid of mixing unrelated media, combining different colored pencils or exploring unorthodox approaches. For example, I sometimes like to combine graphite and colored pencil with ink, starting loosely with pencil and finishing with ink.

As you experiment with combining media you’ll learn to work within some important limitations. For instance you may find it difficult to apply a chalkier medium on top of a slicker medium such as graphite or colored pencil. You’ll also discover you can’t splash heavy washes on thin paper. In fact for many mixed media approaches you may want to consider tougher surfaces such as canvas, sanded paper or pastel cloth. These provide wonderful traction, grabbing onto both dry and wet media and allowing combinations such as charcoal and paint, as we see in Robin Smith’s Marmadu, that wouldn’t be possible on most papers.

Paper

Some artists delight in rummaging through stacks of unusual and expensive papers, but I’m not a paper connoisseur, and I prefer the smooth bond-paper surface that I’ve drawn on since I was a child. Bond paper is not hard to find in letter size, although it takes a little detective work to find my preferred size of 18″ x 24″. Different manufacturers sell large-format bond papers that are acid free and archival, but they vary greatly in tooth and paper weight—try out different brands until you find one that feels right for you. Among the ones I use are Borden and Riley No. 39, a 16-lb layout bond paper that comes close to the smooth, bright-white surface of photocopy paper; and 50-lb Canson Sketch paper, which has a slightly warmer and darker surface. It’s also a little rougher, which I sometimes prefer for the way it grabs my pencil, producing darker lines and value masses.

Slick bond surfaces are not always conducive to vine charcoal or pastel-based media. Believe it or not newsprint is perfect for these. It grabs onto the materials, giving a smooth, gliding effect to one’s value massing and linework. Unfortunately newsprint is also highly acidic, making it yellow and decay rather rapidly. I know many artists who love this ephemeral surface but are forever in pursuit of an archival substitute. The best replacement I’ve found is Arches Text Wove, which shares most of the same properties. I also find that absorbent printmaking papers such as Rives BFK take charcoal and pastel in a similar manner. Take care to work gently on printmaking papers, which don’t have much sizing. Their fibers are delicate and start to pill when erasing or applying material with a heavy hand.

Many good options are available for artists who want to work on toned paper. When I’m working on a toned ground I gravitate toward smoother surfaces, such as Strathmore’s 400 Series Toned and Artagain, as well as Canson Mi-Teintes, preferring the silky, blotter backside of this paper over its more textural front. They allow for delicate, blended rendering, as well as distinctive linework. I’m also fond of the lightly textured surface of Strathmore’s 500 Series Charcoal Assorted Tints paper. You can create a clean, shimmering effect on this paper if you’re careful not to press too hard and fill in its textural valleys. I like to stroke my dark and white pencils gently along the top surface of the paper texture, allowing the resulting tones to vibrate against the color of the paper.

Erasers and 
Other Tools

Some teachers ban erasers in an effort to get students to look closely and commit before making a mark. Certainly an eraser is no substitute for failing to look closely at the model and thinking before you put down a line, but I firmly believe erasers are an important tool when not overused. I subscribe to the view of America’s greatest draftsman, Thomas Eakins, that drawing is a process of revision, that you put down something and then adjust this estimate toward greater accuracy as you work. Just remember to look closely at the model and draw lightly so that you can more easily erase later on.

Erasers are not all created equal, and I’ve found that the best type of eraser can vary depending on the media and paper you’re using. Kneaded erasers are usually effective for adjusting small vine charcoal shapes. Plastic erasers such as those made by Tombow and Staedtler are more efficient at lightening or removing colored pencil, compressed charcoal and carbon pencil from smooth paper. There are also long, pointed plastic erasers that look like mechanical pencils—such as those made by Tuff Stuff and Tombow—which I’ve found indispensable for cleaning up small details and sharpening the edge of a shape. Even though you can roll a kneaded eraser into a sharp point, it won’t give you as clean a shape. Rather these soft erasers create a more blurry edge—which can be useful when you want such an effect.

Unfortunately, erasers harden and become worthless as they get older; they can even smear or rub a line deeper into the paper. Additionally, it doesn’t hurt to reserve separate erasers for black media and for colored pigments, and you should clean erasers frequently to prevent smudge-making pigment from accumulating on them and leaving stains where you want clean paper.

When you keep your erasers new and clean, you will find that they are excellent drawing tools, not only for removing unwanted marks but for making wanted ones, as well. I often lay a broad tone of chalk or charcoal across my figure drawing and then draw light hatch lines into the mass with a pointed eraser to create a modeled effect, much as you might use a white pencil on toned paper. I will sometimes blend a tonal mass with the flat side of a block eraser. On occasion I will press down with a kneaded eraser to lessen the assertiveness of a line. Sometimes I’ll thin out a line by chiseling at its edge with a pointed plastic eraser, making some of the marks more delicate and fainter than other lines for rhythmic purposes. I often do this to imitate the effects of form and light, particularly where the boundary line of a volume faces the light source, or to indicate a softer fleshy form compared to a more distinct line of a projecting bone.

There are many other tools to consider. Razor blades and sandpaper are useful for sharpening pencils. Many artists like to use chamois and stumps to blend charcoal, pastel and graphite for even tones. I prefer to use my fingers for blending small, delicate masses, and I’ll use a facial tissue (sans ointment) to get a broader, even value mass. When using your fingers, it’s important to keep them clean and dry—I usually wipe my finger on a paper towel before each use—otherwise the oils of your skin will interfere with the drawing.

Tip: I find it makes a difference what order you employ various erasers when using more than one type in a single drawing. If I try to erase a deeply inscribed line with a kneaded eraser first, the line becomes even more resistant to subsequent attempts by a plastic eraser. I avoid using the smaller pointed plastic erasers on large areas, since they can embed the pigment into the paper; I’ve found the larger plastic erasers better suited to such tasks.

Changing Things Up

It’s natural to have a favorite material, but try not to become too dependent on any one product or brand. It never fails: After you get used to one type of pencil or paper, it gets discontinued! It’s happened to me many times, for instance with my favorite charcoal pencils and sanguine chalk. Speaking from my experience, I would advise you to experiment with various brands of your favorite drawing medium so that you’re not left in the lurch when a material changes or becomes unavailable. I also advise holding on to pencil nibs—if you’re caught off-guard by a surprise cancellation, you can put them in a pencil extender and get quite a bit more mileage out of them.

Even if they don’t stop making your favorite drawing utensil, you might find it useful to change media once in a while. It’s quite possible to fall into complacency when using the same materials for too long, and switching things up can help maintain your sense of enthusiasm. It can also help break bad habits that might be creeping into your work—many artists develop muscle memory based upon the traction and resistance that the same pencil has against the same paper. After continually using the same materials, you may find that your hand wants to go at the same speed and angle regardless of the subject matter. These habits can get in the way of seeing your subject’s specific shapes and size relationships and can even interfere with the drawing process, for instance by demanding a heavy line when your goals demand delicacy, or vice versa.

Sometimes the change of material can be something as minimal as a change of color to jumpstart your visual perceptions. If you find that your line weight is too heavy for your goals, you might switch to a lighter color, say from a heavy black charcoal pencil to light sanguine pencil. You could also try the opposite tack by using an even darker material to train your hand to back off and use a lighter touch.

There’s no doubt that one’s choice of materials will impact the superficial look of a drawing, and the drawing materials mentioned here are just some of those I’ve found helpful to my particular vision. But in the end it’s the artist who makes the drawing, not the materials. Consider Hendrick Goltzius’ multiple versions of the Farnese Hercules. Whatever material he was using, Goltzius’ intense interest in sculptural volume makes the artworks compelling, giving the images power and lasting artistic importance.
