CHAPTER TWO -- SURFACES AND EFFECTS

(With thanks to The Pastel Journal, where this chapter was originally published, with additional material included here.)


One of the biggest frustrations I experienced when I started using pastels was learning what to expect from various surfaces, which is one of the most basic starting points for all artwork. What surface should you use? There are papers and boards, sandpapers and soft papers, fuzzy and sharp coatings, flat and rigid mounts, thin and thick coatings -- the array is dizzying. I found myself thinking back over my career and realized that after many years of painting in pastels I’ve only scratched the surface of surfaces, if you’ll pardon my pun.

CANSON

I began painting exclusively in pastels in the 1980s, first using Canson Mi-Teintes, as have so many others. I found this fine-textured, lightweight paper modestly priced and readily available. I enjoyed the great assortment of colors. At first I was a little baffled by the texture, which varies from front to back, with a slightly smoother feel to the backside. The screen-like grain on the front (the side that bears the watermark) left so many tiny holes in the painting that I often found myself blending too vigorously and far too often. In some ways this texture might be one of the great drawbacks to Canson, since I tended to over-blend colors, making mud, as well as making some serious dead spots in the surface from my heavy-handedness. This almost discouraged me from continuing my explorations in pastels until I turned the paper over to the softer backside to paint. Soon I realized that I had to carefully plan and execute my paintings, with an eye to the number of layers and the amount of blending it would take, and then began to enjoy success.

ERSTA

A couple of years later I found another surface that opened new possibilities. A workshop with Master Pastelist Albert Handell introduced me to Ersta. Imported from Germany, Ersta is a fine-grained sandpaper with a soft roughness reminiscent of a cat’s tongue. Handell showed us a special technique he used to color the paper when he didn’t want to paint on the light buff color. Using a brush, he painted a light application of Turpenoid over layers of pastel, transforming the dry pigment almost magically into paint. I was liberated by this surface, set free to layer more colors, able to do a certain amount of judicious blending if I was careful, yet discouraged from doing so by sanded-sore fingertips. I found I could achieve fine lines and details that had eluded me before, making soft transitions of color by allowing a lower layer to peek through from below, as well as using techniques such as feathering to quickly mass distant portions of the landscape or give the illusion of reflections in water. I’ll never forget watching Handell swiftly feather a long stick of charcoal over my roughly laid-in creek and suddenly seeing the soft glisten of reflections appear to float out from under his hand. This paper seemed nearly miraculous! I began a long season of working on Ersta, enjoying its strengths and learning about its limitations. Perhaps most disturbing was finding out that the backing paper, made from acidic wood pulp, was not archival. Nonetheless, I enjoyed painting on Ersta for many years. (Note: You can now enjoy the new version of Ersta using UART, which comes in several different grits, and is no longer acidic in content.)

WALLIS


Light From Above, Wallis Professional grade, white, 17" x 12".

At a convention in the mid-1990s I found a new surface introduced by artist Kitty Wallis. She covered her booth walls with her recently developed bright white, deeply toothed sandpaper, tempting the artists who walked by to experiment with pastels strewn across the tables. The walls soon became filled with doodles, swipes, dabs, scribbles and drawings, blended and layered, some areas exquisitely painted, others primitively conceived. It became part of each day to check out what had been done. All of us walked through the vendor’s hall clutching our samples, talking about our plans to use it. My Wallis epoch continues to this day. This incredibly versatile paper is my choice for about ninety percent of my work. I’ve used both the museum grade, which is slightly heavier and a little smoother, and the professional grade, which I recommend for my students. It will take almost anything I give it. I’ve used water to tone it, variously texturing the look by dabbing into the wet pastel mixture with paper towels, spraying into it, scrubbing it with a 3-inch brush to make a scumbled ground, or layering more pastel while the paper is damp, resulting in a rich impasto stroke. I’ve laid it on my rocky driveway and sprayed it with my garden hose to remove a painting, soaked it in the bathtub under water, or simply brushed out offending work with a foam house painting brush. In fact, my experiments with this led to a technique that I’ve found most useful, in which I tone Wallis paper with pastel by vigorously scrubbing it in with a foam brush, making a lovely overall tone in any color, reminiscent of Handell’s toned Ersta. I’ve found that this technique actually allows me to erase portions of my paintings as well, recovering a version of the original color.

PASTELMAT

Pastelmat is a paper that’s rapidly becoming one of my favorite surfaces. I admit that on first touch I was dismayed, almost rejecting it as too soft and lightweight – wimpy, in other words. But once I put it on my board and made some passes using the flat edge of my pastel I was immediately taken with this paper. To the hand it’s somewhat reminiscent of velour or velvet, but pastel adheres to it like tape. Stick pastels, even very soft ones, seem to glide into the paper. For this reason the image needs no fixative, but conversely it isn’t easily erased. However, the depth of tooth allows you to over-paint it, making corrections in the early stages. PanPastels are a perfect match to Pastelmat, as the gossamer thin layers seem almost to fuse with it. Sticks can easily be layered over that, if needed. I’ve also found that you can paint on this paper. It tolerates wet media with no problems, as long as you stretch it as it dries. One thing to bear in mind is that the soft surface can be a little bit fragile, so it's a good idea to keep the glassine supplied with each sheet in place until you're ready to use it. Slight scores in the texture can be filled in with soft pastels, and once painted the paper seems tough and resistant to scratching. Of the eight colors offered my favorites are the buttercup yellow, sienna and dark gray. This paper is really a delight to use.

VARIOUS SURFACES

I’ve made several detours during my career using Canson, Ersta, Wallis and now Pastelmat, experimenting with surfaces such as Pastelbord (nice deep, even grit), Sabretooth (I prefer the white), Hähnemule Velour (extremely soft), Pastel Cloth (interesting textural possibilities), and have even experimented with my own coated boards. I’ve also painted on Schmincke Sansfix, Art Spectrum Colourfix, Rives BFK, Arches Cover, Somerset Velvet, and La Carte Pastel Card.

I don’t remember when I discovered it, but one of my favorites is the La Carte Pastel Card, which has a soft, sandy grain that’s deep enough to accept many layers and comes in pleasing and unusual colors. However, I’ve found that you must not allow any moisture to come in contact with this paper. I discovered this one summer day as I painted beside a mountain pond in Colorado. A storm was threatening, and as I sketched, a blob of white suddenly slid down the paper. I thought a bird had made a critical comment on my work until I realized that a large raindrop had washed away the grainy coating, revealing the bright white backing. Today I use La Carte only on dry days on location or in my studio. I find the springy softness of this surface is worth the drawbacks -- but I don’t even blow on it since others tell me the tiniest bit of saliva can cause trouble. However, you can repair La Carte if needed. One of my clients returned a painting to me, explaining that her dog had drooled on it. Sure enough, there was the telltale bright white. As she stood anxiously nearby, I carefully brushed a layer of Golden Fine Pumice Gel into the spot, let it dry, and then painted over it. It left very little evidence of ever having been damaged. Despite this drawback, La Carte is a delightful surface that lets me blend or paint a tight line, and yet gives a velvety softness when needed.

Years ago I tried Schmincke Sansfix, which felt a little too aggressive compared to Ersta. I recently used it again and this time I found the deep, sharp tooth very appealing. I suspect that years of painting on Wallis have taught me to cope with the spiky tooth somewhat more, though Sansfix is far rougher and sharper than Wallis. I like the slightly slick grainy texture that can be used for so many effects. I can finger blend, carefully of course, but the tooth is deep enough to grab pastel applied over it, arriving at a second, third or fourth textural layer. I particularly favor the dark charcoal color.

When I don’t want texture, however, I use a soft, deep paper such as BFK Rives or Arches Cover, which allow me to blend soft passages thoroughly down into the paper. I was recently introduced to Somerset Velvet, which is very soft, a little like felt. These surfaces require more planning than the sandpapers, which let you erase more readily, but the results can be quite satisfying.

EXPERIMENTAL SURFACES

Occasionally I’ve made my own surfaces when I want to achieve a deep texture, or if I want specific textures in certain areas of my paper. I make a gesso and pumice mixture (see recipe below) and paint it onto the front of museum board. Once it’s no longer tacky, I turn it over and paint a layer of plain gesso on the back to keep the board from curling. When that’s dry I add several coats of the gesso and pumice mixture to the front. I can actually contour the mixture so that the texture in the sky is smooth, the adobe wall has strokes running perpendicular to the ground, or the foliage of the tree is bumpy and uneven. I can use a brayer to roll out smooth spots, dab with paper towels in rough areas, or simply paint it on with a 2-inch brush. Many artists tone their gesso mixture with acrylic paints, which is perfectly acceptable, but I prefer to use a prepared ground such as Art Spectrum Primer when I want colors. My favorite is the Elephant color, a deep purplish-gray that seems to enhance every pastel color I put down on it.

Another experimental surface I’ve enjoyed making utilizes Wallis paper. For several years I’ve painted hummingbirds, which I want to look like precious jewels sparkling in the sky. I found a product made by Schmincke called Tro-Col, which comes in powder form and can be sprinkled onto wet Wallis paper to form a bright gold background. After the paper dries it’s a little like painting on glass, since the paint can be thick, and the gold will rub off to some degree, but with a careful hand the results are dazzling. It’s amazingly brilliant.

I can’t say I’ve tried them all, though I’ve experimented with many different surfaces. As a broad generalization, you won’t go far wrong in matching the feel of the paper to the look you want to achieve, using soft papers for soft subjects and sandpapers for crisply defined ones, but don’t make the mistake of relying on the paper alone to achieve such results. Try different things on various papers to see what appeals to you and what effects you can achieve. My future plans include trying suede board, a surface I know many artists enjoy, doing some further work on Pastelbord, a surface I’ve not used extensively, as well as continuing my experiments with gold and making my own textured boards. If you’re like me, you’ll find two or three favorites, yet have a wonderful time trying new and different surfaces all the time.


RECIPE FOR GESSO AND PUMICE MIXTURE

2/3 cup Acrylic Gesso
1/3 cup water
4 level teaspoons extra-fine pumice (or marble dust, not as gritty)

4-ply museum rag board

small plastic container with lid

1”- 3” brush

Mix gesso, water and pumice together, carefully breaking up any chunks. The amount of pumice may be adjusted. Keep excess mixture in a closed container.

You may find pumice available at art supply stores, ceramic supply houses, or online. I recommend the 4F (fine) grit.

CHAPTER ONE—PASTELS AND OTHER MATERIALS

PASTELS

Pastels are pure, dry pigments mixed with a binder to form the familiar sticks. However, anyone who refers to pastels as chalk will be drummed out of the local pastel society! Why? We’ve worked long and hard to educate the public, explaining these differences: chalk is made of dyed limestone (now mostly gypsum), while pastels are the same pigments used to make familiar paints like watercolors and oils. Usually the sticks are made by combining these powdered pigments and a binder, most often gum tragacanth, rolled into sticks and left to dry. If you look at a particle of pastel under a microscope you’ll see that it has a crystal structure that reflects light in its color. This is why the medium has such clarity and brilliance of color. When I say “pastel,” I’m referring to soft pastels (not oil pastels), but under the soft pastel heading is a range of hardness depending on the ratio of binder to pigment. NuPastels are hard, Rembrandts are medium and Schminckes are soft, but all of them are called “soft pastels.” NuPastels have more binder than pigment, while Schminckes have more pigment than binder. You’ll find a ratio here: as the softness increases the cost usually rises. Pigments are more costly than binders.

Many people ask my favorite pastel brand, and I have to say that I really don’t have one favorite. However, I favor very soft pastels and generally use them in my personal work from start to finish, with only occasional forays into medium-soft brands. I generally use sanded papers and boards that provide deep tooth, resulting in a creamy, thick painterly look to the pastel application. This is my choice of technique and shouldn’t be construed as the only way to do it. In the classroom I’m far more interested in the student finding the materials that will work best for her chosen mode of expression.

For those just starting on the pastel journey I offer a caution: Pastelists are commonly heard to cry, “I need more colors!” In fact, I’ve had students complete an eight-week course of classes with a selection of only sixteen colors and learn a tremendous amount about creating various colors and controlling values by overlapping layers of colors, but I assure you that at the end of the class they invested in more pastels. The habit can become almost addictive. Because at this writing there are more than 5,500 individual color sticks available on the market (according to Multi-Brand Color Chart of Pastels, Huechroval, 2008), with more arriving all the time, it seems the cry will continue to be heard. If you find yourself becoming intoxicated with this versatile medium the chances are you’ll say it, too.

If you’re new to pastels I recommend purchasing two sets, one somewhat harder, and one much softer. The advantage to this is twofold. First, you’ll find the harder pastels more inexpensive, but you must have some softer brands in order to understand how differently they cover the paper. Second, you’ll find that working soft over hard pastels is a time-tested method that may give you more comfort as you move from thinking of the medium as one of drawing into one of painting. Don’t think that you can buy a medium-hard pastel set to do it all -- it simply doesn’t work that way. Shop around to find the best buy, which will often be found online at one of the large catalog stores, but in the end I believe you’ll benefit from trying different kinds of pastels to find the quality that works best for you.

My usual recommendation is a large set of relatively inexpensive harder pastels, such as NuPastels, and a somewhat more modest-sized set of very soft pastels, such as Great American. (I offer a hand-selected set of colors through Great American that many students working in the southwestern United States have found useful.) However, keep in mind that there’s a dizzying array of brands from which to choose. Whenever possible, purchase a few sticks of each of the brands that are available from open stock at your local art supply store before buying a larger set, or look into purchasing such a “sampler” from an online retailer. That way you can experiment to find out how they feel, plus you can apply them to all kinds of pastel painting surfaces to see what appeals most to you.

PAPERS AND BOARDS
There are two key features that pastel painting surfaces have: tooth and texture. The best test you can use to determine the texture or tooth is the hand. You need to feel the surface to see if it’s fine-grained and machine smooth, rough and scumbled, or deep, soft and velvety.

Tooth generally refers to a coating added as a surface treatment to a substrate, whether it’s made by a manufacturer and sprayed on in a factory or mixed up in your studio sink and painted on your paper or board. Texture is generally patterned into the paper itself. It usually refers to the weave or other regular marks left on the surface of the paper that will show up more clearly when pastel is stroked across it. The pulp of the paper may be apparent, resulting in a slightly striated, bumpy or screened surface. Some of these papers have a laid surface, which is a patterned texture of parallel lines impressed in each sheet. Texture doesn’t have as much depth as tooth and won’t hold as much pastel in place, sometimes requiring a fixative or other finish to stabilize the pastel.

Canson Mi-Tientes is often the first paper people try, if only because it’s commonly available, inexpensive and comes in a beautiful range of colors. It’s lightweight and easily handled, and invites a drawing technique in particular. It has a nice woven textural quality that resembles the look of canvas. However, because it has little tooth it’s not suited for use with the softest of pastels, which may quickly become muddy in inexperienced hands. Instead, most artists prefer to use a slightly harder pastel on Canson.

Sandpapers are usually made on a backing sheet of some kind, covered with a coating that contains pumice, sand, marble dust or other silicates that provide the irregularity needed to hold pastel in place. For instance, sandpapers are generally fine-textured and rather smooth to the touch, but have deep tooth. You can easily work with both hard and soft pastel brands on sandpapers, which customarily hold many layers of pastels. One excellent advantage is that sandpapers can be erased and reworked to some degree. Another thing to keep in mind about painting on any of the sandpapers is that very soft pastels fill the grain of the tooth rather quickly. This does not mean they’re inappropriate to use on that surface, just that you might want to use a light hand in applying the softer pastels so that they’re not needlessly wasted.

In my classroom I recommend using Wallis Professional grade sandpaper, which I use about 90 percent of the time in my studio. It’s a wonderful, versatile surface that has very few limitations. It has the tooth necessary to hold the little pastel crystals in place and accepts many layers of pastels without filling up and shedding pastel. It has a nicely machined surface texture and the bright white color can be easily toned to any color you desire. I suggest beginning students try Wallis sandpaper first. (See the chapter on Surfaces and Effects for more information.)

GADGETS
Suppliers are always coming up with new products for pastelists, but some of the most innovative and useful tools around are called Colour Shapers. These gadgets have a handle like that of a fine brush, but rather than being tipped with bristles they have a soft silicone point (a rubber tip, most of us say) that can be used to move pastel pigment around much the way your finger does. How many times have you wished that your finger were small enough to reach into a little corner? Using one of these, it is. Colour Shapers come in soft and firm grades for different effects, as well as five different shapes and sizes. Use them to grab the pastel and move it around much the way you use brushes to move paint. Enjoy the way you can soften and blend edges and colors or add definition with the side. I suggest you buy the flat chisel shape, but be aware that the square corners will slowly become rounded as you use it. The tips wipe clean easily so that you don’t contaminate colors.

Another innovation are the Sofft® tools, which are dense foam pads in various shapes that you can use to move and blend pastel. I use the larger round, flat ones to mass and smooth transitions, or remove a light layer of color when needed. The wedge-shaped and squared tools are useful to grab and transplant a long line of color from one spot to another, or to create grassy strokes.

I often use a plain white plastic eraser for many effects, too. It’s very handy on the Wallis paper, where I use it to erase areas in the tone, restoring the bright white of the paper, as well as to literally erase mistakes. The eraser becomes quite black with use, of course, so occasionally I’ll briskly scrub it on the underside of a table, restoring a small section that’s bright and clean, and use that spot to do some clean-up or details in the drawing stage.

CLASSROOM SUPPLIES
If you were to sign up for one of my classes today, this is the list you would receive .
The following is a list of the materials I use. Don’t feel that you have to have everything on the list. Some materials will be available for sale in class. Bring what you already have on hand, and feel free to contact me with questions.

Pastels:
*Please note: we are using SOFT pastels, sometimes called ‘chalk’ or dry pastels, NOT oil pastels. Ideally you want a selection of hard- and soft-textured pastels, but no one brand makes both. Any of these will work:
Schmincke Pastels (very soft)
Great American Pastels (very soft)
Ludwig Pastels (very soft)
Mount Vision Pastels (soft)
Girault Pastels (medium soft)
Cretacolor Carré Pastels (hard)

If you are newly purchasing soft pastels, I recommend a set such as one of these (in no particular order): Great American Art Works Southwest Landscape sets (39- or 78-piece), Ludwig Pastels Maggie Price Basic Value set (60-piece), Mount Vision Landscape set (50-piece), Schmincke Assorted Soft Pastels (60-piece), Girault Landscape Set (25- or 50-piece), Unison Pastels half-stick sets (63- or 120-piece). You might additionally purchase a set of harder pastels such as Cretacolor Carré Pastels (72-piece) or Faber-Castell Polychromos Pastels (60- or 120-piece).

No matter which set(s) you choose, try to also bring the following if possible:One stick of either Schmincke or Great American white
One stick each of Schmincke Ultramarine Blue 0620 and Cobalt Blue 0640
One stick of Nu-Pastel bottle green 298-P
One stick each of Unison Green 13 and A-43

I suggest you purchase a small plastic container with a tight fitting lid and fill it about halfway with plain old dry cornmeal to safely transport the pastel sticks you’re using to complete a painting.
