Hand a child a box of oil pastels and a box of chalk pastels, and within minutes the difference is obvious. One glides on in thick, waxy, bright strokes and barely smudges. The other leaves soft, powdery color that blends with a fingertip and coats everything nearby in dust. Both are called “pastels,” but they behave almost like different media.
The oil pastels vs chalk pastels choice affects how you blend, what paper you need, how messy the session gets and how you protect the finished piece. This guide covers all of it, with practical advice for kids, beginners and artists choosing between the two.
Quick answer: Oil pastels are pigment bound with oil and wax, so they are creamy, bold, slow to smudge and never fully dry; they blend by pressure, layering or a little solvent. Chalk pastels (soft pastels) are pigment bound with a small amount of gum or binder, so they are powdery, blend easily with fingers or tools, and produce soft, delicate effects but smudge and create dust. Oil pastels are usually the tidier, easier choice for young kids and bold color; chalk pastels suit soft blending, atmospheric landscapes and portraits, and need fixative or framing under glass.
What Oil Pastels Are
Oil pastels combine pigment with a non-drying oil and wax binder. The result is a stick that feels a bit like a crayon but softer and creamier. Because the binder does not dry like paint, oil pastel artwork stays slightly soft and can be smeared if pressed, even years later.
Key traits:
- Bright, saturated color and good opacity in many shades
- Minimal dust and less smudging during normal handling
- Blending by layering, pressing colors together, or using a blending stick or a little odorless solvent
- Works on paper, card, wood, canvas and many other surfaces
- Does not need fixative in the same way chalk does, though protective sprays exist
What Chalk Pastels Are
Chalk pastels, also called soft pastels, are made from pigment mixed with a small amount of binder, sometimes with fillers such as chalk or clay. They come in sticks that crumble and release powder as you draw. Hard pastels and pastel pencils are firmer variations for detail.
Key traits:
- Soft, velvety color with a matte finish
- Very easy blending with fingers, tissues, blending stumps or sponges
- Produces dust; fine particles settle on surfaces and hands
- Needs paper with “tooth” (texture) to grip the powder
- Smudges easily; finished pieces need fixative and/or glass framing
Note that “chalk pastels” are different from sidewalk chalk and from chalk-style paints. If you are looking for chalky color that kids can use outdoors or wash away, our roundup of the best chalk paints for kids covers washable options.
Oil Pastels vs Chalk Pastels: Comparison Table
| Feature | Oil pastels | Chalk (soft) pastels |
|---|---|---|
| Binder | Oil and wax | Small amount of gum or binder |
| Texture | Creamy, waxy | Powdery, dry |
| Color look | Bold, glossy-to-satin, saturated | Soft, matte, luminous |
| Blending | Layering, pressure, blending stick or solvent | Fingers, stumps, tissue, sponge |
| Dust and mess | Low dust; waxy residue on hands | High dust; powder on hands and table |
| Smudge risk after finishing | Moderate; stays soft | High without fixative |
| Drying | Never fully dries | No drying; sits as powder |
| Paper needs | Most heavy papers; tooth helpful but not essential | Toothy pastel paper or sanded paper preferred |
| Detail | Moderate; thick sticks | Good with hard pastels and pastel pencils |
| Protection | Glass or a specific oil pastel fixative | Workable fixative and glass framing |
| Ease for young kids | Easier and tidier | Messier; best with supervision |
How Blending Works in Each Medium
Blending oil pastels
- Layering: apply a light layer of one color, then a second color on top with firm pressure. The colors mix on the paper.
- Scumbling: lightly drag a color over another so both show through.
- Blending stick or colorless pastel: a clear wax stick pushes colors together without adding pigment.
- Solvent blending: a small amount of odorless mineral spirits or baby oil on a cotton swab or brush melts the pastel into a paint-like wash. This is best for older students with adult supervision and ventilation.
- Sgraffito: scratch through a top layer to reveal color underneath, a favorite technique for kids.
Blending chalk pastels
- Finger blending: the simplest method, though skin oils can affect the surface slightly over time.
- Blending stumps and tortillons: rolled paper tools for controlled blending in small areas.
- Tissues or soft cloths: great for skies and smooth gradients.
- Layering with light pressure: building multiple light layers keeps colors fresh.
- Wet blending: some artists brush water or alcohol over soft pastel underpainting, depending on the paper and pastel type.
Paper and Surface Choices
| Surface | Oil pastels | Chalk pastels |
|---|---|---|
| Standard drawing paper | Works, but thin paper may tear with pressure | Limited layers; powder slides off |
| Heavy mixed-media paper | Very good | Fair; less tooth |
| Pastel paper (textured) | Good | Very good |
| Sanded pastel paper | Usable but wears sticks | Excellent; holds many layers |
| Colored construction paper | Fun for kids | Fun for kids; dusty |
| Canvas or board | Good when primed | Needs a pastel ground |
Toned or colored paper works well for both media. Mid-tone grays, blues and browns make highlights pop and save time filling in backgrounds.
Mess, Cleanup and Safety
Oil pastels leave a waxy residue on hands, tables and clothing but create little dust. Cleanup usually involves wipes, soap and warm water. Wax may need extra scrubbing on fabric.
Chalk pastels create fine dust that settles on surfaces and can drift into the air. Good practices include:
- Tapping the board over a trash can instead of blowing dust off.
- Working at an angle so dust falls downward rather than across the image.
- Wiping tables with a damp cloth rather than sweeping.
- Keeping food and drinks away from the work area.
- Checking labels for safety information; some professional pastels contain pigments that should not be inhaled or ingested.
For young children, choose products labeled for children and supervise use, especially with chalk pastels.
Protecting Finished Artwork
Oil pastels
Because oil pastels never fully harden, finished work stays slightly soft. To protect it, frame under glass with a mat so the glass does not touch the surface, or use a fixative specifically designed for oil pastels. Store unframed pieces with a sheet of glassine or parchment over the top.
Chalk pastels
Chalk pastel work needs more protection. A workable fixative sprayed lightly between layers or at the end reduces smudging, though it can darken some colors. Many pastel artists use fixative sparingly and rely on framing under glass with a mat and a small gap so loose dust falls behind the mat rather than onto the glass.
Which Is Better for Kids?
For preschool and early elementary children, oil pastels are usually the easier choice. They are bright, forgiving, low-dust and do not require special paper. Techniques like layering, crayon-resist with watercolor and sgraffito are simple and fun.
Chalk pastels can be wonderful for older kids who enjoy blending and soft effects, especially for skies, sunsets and animals. Set up a dedicated space, provide wipes and smocks, and protect finished pieces by storing them in clear sleeves or framing them under glass.
Grip matters too. Oil pastels are usually thicker and sturdier, which suits small hands still developing control. Chalk pastels snap easily under pressure, so younger children may end up with a box of fragments. That is not a problem for art-making, but it can be frustrating for a child who expects the stick to behave like a crayon. Showing kids how to use the side of a broken piece turns that frustration into a new technique.
Which Is Better for Different Subjects?
| Subject or style | Better medium | Why |
|---|---|---|
| Bold illustrations and cartoons | Oil pastels | Saturated, opaque color |
| Soft skies and sunsets | Chalk pastels | Seamless blending |
| Portraits with subtle skin tones | Chalk pastels | Delicate gradations; pastel pencils for detail |
| Expressive abstract art | Either | Oil for thick texture, chalk for soft layers |
| Mixed media with watercolor | Oil pastels | Wax resists watercolor washes |
| Outdoor sketching | Oil pastels | Less dust, no fixative needed on site |
| Landscapes with atmosphere | Chalk pastels | Soft edges and luminous layers |
Cost and Value
Both media come in student and artist grades. Student oil pastel sets are usually inexpensive and come in large color ranges, which makes them a common classroom staple. Artist-grade oil pastels are softer, creamier and more pigmented, with a noticeable price jump.
Chalk pastels follow a similar pattern. Student-grade sets tend to be harder with more filler, while artist soft pastels are very soft and intensely pigmented. Because soft pastels wear down quickly and need special paper, the overall cost per finished piece can be higher than with oil pastels.
For kids and beginners, a mid-sized student set of either medium is plenty. Upgrade a few frequently used colors, usually white and the darkest values, before upgrading the whole set.
Simple Project Ideas
Oil pastel projects
- Watercolor resist: draw with oil pastels, then paint over with watercolor. The wax repels the paint and the drawing shines through.
- Sgraffito night sky: layer bright colors, cover with black, then scratch stars and shapes with a toothpick.
- Bold animal portraits: outline in black and fill with saturated, layered color.
Chalk pastel projects
- Sunset silhouettes: blend warm bands of color, then add a dark silhouette of trees or a skyline.
- Stencil galaxies: rub pastel off the edges of paper stencils for soft-edged planets and nebulae.
- Snowy landscapes on dark paper: use white and pale blues on navy or black paper for glowing snow scenes.
Can You Use Oil and Chalk Pastels Together?
Mixing them on the same piece is possible but tricky. Chalk pastel does not stick well on top of oil pastel because the waxy surface has no tooth. The reverse, oil pastel over chalk, can work for accents. If you want to combine them, plan separate areas or use chalk for an underlayer and oil for bold final marks.
Storing Pastels So They Last
Oil pastels soften in heat, so keep them away from sunny windowsills and hot cars, and store them in their tray so the sticks do not stick together. Wrapping paper sleeves help keep fingers clean; peel back only what you need.
Chalk pastels break easily and pick up color from neighboring sticks. Store them in a tray lined with foam or a box with dry rice or cornmeal, which some artists use to gently clean the sticks as they are shaken. Broken pieces are still perfectly usable, especially for side strokes.
Beginner Tips for Each Medium
Oil pastels
- Start light and build pressure gradually; heavy first layers fill the paper’s tooth quickly.
- Keep a paper towel handy to wipe the tip of each stick before switching colors.
- Place a scrap sheet under your hand to avoid smearing.
- Use light colors on top of dark for highlights at the end.
Chalk pastels
- Work from dark to light and from hard to soft pastels.
- Use the side of the stick for broad areas and the edge for lines.
- Do not over-blend; leaving some strokes visible keeps the work lively.
- Break sticks into smaller pieces for easier side strokes.
FAQs
What is the main difference between oil pastels and chalk pastels?
Oil pastels use an oil and wax binder, giving creamy, bold color that stays soft. Chalk pastels use very little binder, giving powdery, blendable color that smudges and needs protection.
Are oil pastels or chalk pastels easier for beginners?
Oil pastels are usually easier and tidier for beginners and young children. Chalk pastels are easier to blend smoothly but require more care with dust and smudging.
Do oil pastels ever dry?
No. Oil pastels stay slightly soft indefinitely, which is why framing under glass or using a specific fixative helps protect them.
Do chalk pastels need fixative?
Fixative is recommended to reduce smudging, though it can darken colors slightly. Framing under glass with a mat also protects finished work.
Can you blend oil pastels with water?
No. Oil pastels resist water. They blend through layering, pressure, blending sticks or a small amount of oil-friendly solvent.
Are chalk pastels the same as sidewalk chalk?
No. Artist chalk pastels are more finely made with richer pigment. Sidewalk chalk is designed for outdoor play and washes away more easily.
Final Thoughts
Oil pastels and chalk pastels both earn a place in an art kit, but they serve different goals: oil for bold, low-mess color and chalk for soft, luminous blending. For kids, oil pastels are usually the gentler start, with chalk pastels introduced once they are ready for a dustier medium.
