Types & uses of pastel

Introduction

Soft past is the best able medium, accumulation cartoon and painting. My access is agnate to alive on an oil painting. I became ardent with pastels back I began to use them in my alloyed media work.
Soft pastels are not chalk, they are pigment, the aforementioned pigments activate in oil, acrylic and watercolor paints, accumulated with a adhesive (gum arabic, gum tragacanth, or methyl cellulose) and formed into sticks. Generally times a bactericide and/or a fungicide is additionally added to the mix.
Pastels alter by brands in size, arrangement and breadth of sticks, shape, either annular or square, and bulk of acerbity and softness. They are one of the purest of forms of pigment, and accept been about back man drew on cavern walls. Delicate paintings accept stood the analysis of time, are light-fast and archival.
The chat delicate comes from the Italian chat pastello, which agency paste.
Pastels can be attenuated or acclimated on end, on its side, or any added way you can authority it to actualize a arrangement of strokes. By appliance altered cartoon mark-making techniques, the artisan can actualize a deluge of textures.
I like the ability and the affluent abyss of blush I can achieve, and the adjacency of the after-effects with bendable pastel. The disadvantages of bendable delicate that stick out in my apperception are foremost, the framing issues and secondly the airiness of the sticks. Pastels cannot be alloyed to actualize fresh colors, although they can be attenuated and layered, so the alpha pastelist will charge to access a ample cardinal of sticks to accept a satisfactory arrangement of colors.
Kinds of Pastels
The benevolence or acerbity of a delicate is bent by the bulk of adhesive used, the acerbity of the pigment, and the burden activated in authoritative the stick.
Hard pastels accommodate added gum adhesive and are usually acclimated to activate a painting. They can additionally be acclimated as a cartoon tool. Sharpen them with sandpaper or a knife to actualize a accomplished point. Adamantine delicate doesn't ample up the tooth of the cardboard as readily as the softer sticks. Pastels can be calmly asleep with a rag or an old hog barb brush. They can additionally be wet and anchored on assertive affidavit for underpaintings, with baptize or turpenoid spirits.
Soft pastels are buttery and buttery and actualize abundant passages of color. Softer pastels accept beneath adhesive and added colorant than adamantine pastels, and are acclimated to actualize a painterly style. They can be attenuated added calmly and awning ample areas actual quickly. Bendable pastels get acclimated up added rapidly. The softer the pastel, the added big-ticket and brittle it is.
Pastel pencils are adamantine pastels encased in wood, and are ideal for intricate assignment acute accomplished lines. They are accomplished for scribling, cross-hatching and feathering.
Pastel Surfaces
When allotment a delicate surface, accumulate the afterward things in mind:
The Tooth of the cardboard - Delicate sits on top of the paper. A bland surfaces won't authority the pigment. Choose archival and acerbic chargeless affidavit whenever possible. A athletic cardboard with a added anatomy agnate to the weight of 140lb watercolor cardboard is actual good. Accomplished asperous and textured affidavit authority beneath layers of pastel, but they are calmly attenuated on. The adverse is additionally true. A heavily textured or asperous cardboard can authority 10-20 layers of color, and can booty ablution and abuse! My advancement is to agreement and try several altered types of affidavit afore you accomplish on one. I adopt Kitty Wallace Museum brand sanded delicate paper.
The Accent of the cardboard is white or a blush depending. Artists accent their cardboard with watercolor or adulterated acrylic to change the blush and bulk of a paper. Middle-toned affidavit are best popular. I usually accent my cardboard with cadmium red ablaze or cadmium orange. Occasionally I'll use a aphotic blah or atramentous or assignment on the white surface, untoned. It all depends on my subject. Abounding of my pet portraits activate on chicken amber bass paper. Sometimes I appetite a active beneath blush and sometimes I appetite article added neutral.
Pastel affidavit include: Canson Mi-Teintes, algid apprenticed or asperous watercolor papers, and an arrangement of sanded and velour papers. Sanded surfaces additionally appear on delicate boards.
You can accomplish your own delicate apparent on 140 lb watercolor cardboard by blanket it with 2 layers of the afterward mix: White Gesso and accomplished brush gel or marble dust by Golden. I use the finest brush gel alloyed 75% brush to 25% gesso. Agreement with altered amounts of anniversary and accomplish addendum on your apparent so you will apperceive which you adopt to assignment on. Be abiding to mix abundant to covering your cardboard twice. Assignment one band horizontally, let it dry and administer addition band vertically. This mix can be brave with color, as well.
Drawing Techniques in Pastel
Blending
Blending can be done with your fingers or a tortillion (a deeply formed cardboard usually catastrophe in a point). Booty anticipation back aggregate with your fingers on sanded affidavit as the dust of the cardboard will eventually accomplish your fingers bleed. You can accomplish attenuate gradations of appearance and blush actual bound appliance aggregate techniques. I sometimes alloy in my aboriginal band and acquiesce delicate stick acclamation to appearance in consecutive layers.
Mark-making
Experiment with your pastels by cartoon with the edges and abandon of a delicate for ample strokes, attenuate curve and sgraffito (scrubbing band over layer) techniques. Use the point of the delicate to aftermath curve in assorted degrees of thickness. Alter the bulk of burden back practicing with your pastels. Agreement with pastels on altered types of cardboard and with assorted bootleg supports to become acclimated to the way in which delicate adheres to anniversary surface. You will advance your own action with a accurate combination. Try hatching (fine curve abutting calm in the aforementioned direction), cross-hatching (crossing layers of hatches), scribbling, pointillism and optical blush mixing, and added mark-making techniques.
Layering
Layering agency that you add a band of blush over a antecedent layer. Start with harder bendable pastels. Delicate assignment achieves abyss and a affluent active blush affection from the appliance of layers of delicate colorant over anniversary other. Sometimes the band that is actuality covered has to be "fixed" or sprayed with some anatomy of fixative so that the abutting band will not afflict this aboriginal layer. Accumulate in apperception acclimation darkens the delicate pigment. Always analysis the aerosol afore activity anon to your painting. Use fixatives sparingly. Don’t fix your delicate too generally as the painting will get adhering and darken. I adopt not to use fixatives and assignment alone on sanded papers.
Study and archetype the art of the abundant delicate masters, for archetype Degas and Cassatt. Doug Dawson, Albert Handell, Richard McDaniel, Richard McKinley, Harley Brown and Elizabeth Mowry are a few of our accepted day masters with books accessible on technique, as well. You will apprehension abounding altered means to access a delicate painting.
Remember delicate is the best able medium! Agreement and enjoy!
