This professional-grade, rigid support represents the "sturdy" alternative to flexible pastel papers. It is a 1/8" (3mm) high-density, FSC-certified Hardbord™ panel coated with a proprietary acid-free clay and gesso ground that is infused with fine marble dust. It is the premier choice for artists who require a warp-resistant surface that can withstand aggressive wet-media underpaintings and multiple heavy layers of dry media. It is essentially a "sanded paper" on a museum-quality board, offering the highest level of dimensional stability for both studio and plein air work.Technical Specifications & PropertiesStructural Composition: FSC-Certified Aspen wood fibers. The core is an eco-friendly, high-density hardboard produced without formaldehyde or harmful VOCs.Technical Advantage: Unlike standard MDF or thin illustration boards, this panel is engineered for warp resistance, ensuring it stays flat even when subjected to extreme moisture or atmospheric changes.Surface Matrix: Kaolin clay and gesso with marble dust granules.Tooth Profile: The marble dust creates a granular, "toothy" surface that is more durable than traditional paper fibers. It is designed to be highly absorbent, which is a critical technical difference from resin-bonded sanded papers like UArt.Proprietary Sealing: Features Archiva-Seal™ technology. This unique barrier layer prevents Support Induced Discoloration (SID)—a process where tannins from the wood support can seep into the gesso and yellow the painting over time.Wet-Media Resilience: Industrial strength. You can apply heavy washes of watercolor, acrylic, or alcohol-based inks to tone the board. Because it is a rigid panel, it eliminates the need for taping or stretching paper.Format & Color: Available in a 1/8" flat profile and several "cradled" depths (up to 2"). It comes in four museum-quality, lightfast colors: White, Grey, Sand, and Dark Green.Pro Tip: The White version is frequently used by professional artists who wish to "custom-tone" their background with a thin acrylic wash before applying pastels.Working Techniques & Performance NotesLayering Capacity: Superior. The clay-and-marble surface acts as a mechanical "trap" for pigment. It can hold more layers than traditional pastel paper (typically 10+ layers), allowing for the deep saturation required in professional landscape and portrait work.Mixed-Media Performance: It is technically rated for charcoal, Conté Crayon, colored pencils, and gouache in addition to pastels. The firm surface allows for high-pressure marks that would puncture or tear standard paper.Correctability: Washable. One of the most unique properties of this board is that you can "reset" an area. By using a damp cloth or a soft toothbrush with water, you can lift pastel pigment back to the original clay ground without damaging the texture.Dust Mitigation: Because the marble dust tooth is deep, it tends to hold the pigment more securely, resulting in less "fallout" dust collecting at the bottom of a frame compared to smoother papers.

Art Spectrum (Australia) is a world leader in sanded pastel surfaces. Their Colourfix™ range is unique because it isn't just a paper—it is a chemical system. The "tooth" is created by screen-printing a gritty acrylic primer onto heavyweight watercolor paper. This makes it one of the most durable and versatile surfaces in the world, capable of handling extreme scrubbing, washing, and mixed media.1. The Colourfix Paper LinesAll Colourfix papers are based on 300gsm acid-free, hot-pressed European watercolor paper. The addition of the primer brings the total weight to 340gsm.Colourfix Original (Medium Tooth)The Standard: This is the flagship product. It has a medium, sanded grit that holds multiple layers of pastel without the need for fixative.Texture: Visible "screen-printed" pattern (fine dots) that can show through thin layers of pastel.Best For: General pastel painting, heavy layering, and "painterly" styles.Colors: Available in 20 lightfast colors, including the popular "Clear" (which shows the natural paper color).Colourfix Smooth (Fine Tooth)The Detailer: Introduced to compete with Clairefontaine Pastelmat. It has a much finer, velvety grit.Texture: Soft to the touch and less abrasive on fingers. It is much easier to achieve sharp lines and fine details.Behavior: Holds fewer layers than the Original but allows for much smoother blending.Best For: Highly realistic portraits, wildlife art, and pastel pencils.Colourfix Rough / Supertooth (Coarse Tooth)The Heavyweight: Formerly known as Supertooth, this has a very aggressive, large-grained grit.Behavior: It "eats" pastel sticks rapidly but can hold an incredible amount of pigment. It is nearly impossible to fill the tooth completely.Best For: Large-scale works, expressive landscape painting, and building up massive impasto-like layers of pastel.2. Colourfix Primers (The "Liquid Tooth")One of Art Spectrum's most famous innovations. This is the exact same grit used on the factory paper, sold in jars so you can make your own surfaces.The Concept: A quick-drying, acrylic-based primer containing silica (grit). It bonds to almost any non-greasy surface, including wood, canvas, ceramic, glass, plastic, and metal.The Variations: Available in Original, Smooth, and Supertooth formulas to match the papers.Key Features:Tintable: You can mix the primers with Art Spectrum inks, gouache, or acrylics to create custom-colored backgrounds.Intermixable: You can mix different primer colors together (e.g., mixing blue and white to get a sky blue ground).Clear Primer: Appears milky in the jar but dries completely transparent. This allows you to turn a beautiful piece of wood grain or an existing watercolor painting into a surface that will accept pastels.Application: Can be applied with a brush, sponge, or roller. For a smooth finish, a foam roller is best; for a textured "painterly" ground, use a stiff hog bristle brush.3. Colourfix Optimum BoardThe professional "No-Warp" support.The Build: A high-density, acid-free foamcore board screen-printed with Colourfix Original Primer.The Secret: It contains a micro-thin layer of aluminum inside the board. This prevents the board from warping or bowing, even if you apply heavy wet underpaintings (alcohol or water).Best For: Professional works intended for high-end framing, plein air painting (lightweight but rigid), and mixed media.4. Technical Characteristics & TipsWet Media Compatible: Because the base is watercolor paper and the primer is acrylic, Colourfix is 100% waterproof and alcohol-proof. You can use heavy washes of watercolor, ink, or alcohol-thinned pastel as an underpainting.Erasability: The surface is incredibly tough. You can use a stiff brush or even a damp cloth to scrub pastel off and start over without damaging the "tooth."Fixative Warning: Fixatives will darken the colors on Colourfix more significantly than on unsanded papers. Because the tooth holds so much pigment, many artists skip fixative entirely.Clear Primer Tip: If you want to use the Clear Primer over a drawing, apply it in thin, quick strokes. Over-brushing can reactivate the drawing underneath and cause smearing.5. Summary ComparisonOriginal Paper: Medium grit / Visible pattern / High pigment capacity / Best for general use.Smooth Paper: Fine grit / Velvety feel / Best for fine detail & pastel pencils.Supertooth: Coarse grit / Massive capacity / Best for large expressive works.Primers: Liquid grit / Turn any surface into pastel paper / Tintable / Available in 20 colors.Optimum Board: Rigid / Aluminum core (No warping) / Best for professional framing.

Canson (France, est. 1557) is arguably one of the most famous paper mills in the world. For pastel artists, Canson represents the "Global Standard." Their papers are divided into two distinct categories: Textured Paper (where the texture is pressed into the fibers) and Sanded Paper (where a gritty coating is applied to the surface).1. Canson Mi-Teintes This is the most popular pastel paper in the world. If you buy a "pastel pad" at a craft store, it is most likely Mi-Teintes.The Composition: 50% cotton. It is a heavy, acid-free drawing paper (160g).The "Dual Texture" Feature:Side A (Honeycomb): This side has a heavy, mechanical "honeycomb" or "birdseye" texture. It is designed to grab large amounts of pastel.Side B (Fine Grain): The reverse side is much smoother with a faint felt grain. It is better for detailed work or colored pencil.The Color Range: Famous for its palette of over 50 colors, ranging from "Touch of Sand" to "Stygian Black."Best For: Soft pastels, charcoal, and crayon. It is a "low-capacity" paper, meaning after 3 or 4 layers, the texture fills up and the pastel will start falling off.2. Canson Mi-Teintes TouchThis is a completely different product from standard Mi-Teintes. It is a "sanded" paper.The Surface: It has a micro-abrasive coating (similar to very fine sandpaper or a soft emery board).The Benefit: Because the surface is "toothy" and gritty, it can hold many layers of pastel. You can apply 10+ layers and the paper will still grab the pigment.Liquid Compatibility: It is a "wet media" friendly surface. You can use water, alcohol, or turpentine washes on this paper without it buckling or the grit washing away.Best For: Professional "painterly" pastel work, heavy layering, and mixed media.3. Canson Ingres VidalonA traditional "Laid" paper for classical drawing.The Texture: "Laid" finish. This means it has fine, parallel horizontal lines (resembling old handmade paper from the Renaissance).Weight: Lighter than Mi-Teintes (100g).Behavior: It provides a very specific "striped" texture to your strokes. It is not designed for heavy layering.Best For: Classical portrait studies, charcoal "Academic" drawings, and quick sketches where the paper color does most of the work.4. Comparison: Mi-Teintes vs. Mi-Teintes TouchTexture: Mi-Teintes is pressed (Honeycomb pattern); Mi-Teintes Touch is sanded (grit/sandpaper feel).Layering Capacity: Mi-Teintes is low (3–4 layers); Mi-Teintes Touch is high (10+ layers).Durability: Mi-Teintes is for dry media only; Mi-Teintes Touch handles wet washes (alcohol/water).Detail: Mi-Teintes is better for fine grain (reverse side); Mi-Teintes Touch is better for broad painterly strokes.Price: Mi-Teintes is affordable; Mi-Teintes Touch is premium.5. Summary ChecklistMi-Teintes: 50% cotton / Honeycomb texture / Dual-sided / Best for standard pastel work.Mi-Teintes Touch: Sanded surface / High layering capacity / Wet media safe / Best for professional art.Ingres Vidalon: Laid finish (lines) / Lightweight / Traditional style / Best for charcoal portraits.Main Tip: If your pastels are "sliding off" the page, you have reached the limit of Mi-Teintes. Switch to Mi-Teintes Touch (sanded) to keep layering.

Clairefontaine Pastelmat is arguably the most disruptive innovation in the pastel world since the invention of the pastel stick itself. It is a 360 gsm (170 lb) card with a unique cellulose-based velvety surface. Unlike traditional sanded papers that use industrial abrasives (like aluminum oxide), Pastelmat uses a matrix of fine plant fibers to create "pores" that swallow pigment. It is the premier choice for hyper-realistic artists because it provides an extreme "grip" for multiple layers while remaining soft enough to allow for finger blending and fine-detail pencil work without destroying tools or skin.Technical Specifications & PropertiesSurface Composition: Organic cellulose fibers. The surface is created by an adhesive coating of microscopic cellulose particles.Technical Advantage: Because the grit is organic rather than mineral, it is non-abrasive. This results in 30-40% less pastel consumption compared to sanded papers, which "shave" the sticks aggressively.Absorbency & "Tooth": Despite feeling smooth to the touch, the surface acts like a pigment sponge. It can hold up to 10-12 layers of soft pastel before the tooth is saturated.Fixative-Free Performance: The fiber matrix "locks" the pigment in place so effectively that most artists do not use fixative. This preserves the original vibrancy and velvet look of the pastels, which often darken or shift color when sprayed.Water & Solvent Resistance: Extreme. Pastelmat is completely water-resistant.Mixed-Media Utility: It is a favorite for wet underpaintings using water, denatured alcohol, or odorless mineral spirits. It can even be used for acrylics, watercolors, and gouache as a standalone surface.Dust Mitigation: Because the fibers grab and hold the pigment rather than letting it sit on top of a grit, Pastelmat produces significantly less dust than sanded papers. This makes it a safer choice for artists working in small or poorly ventilated home studios.Erasability: Uniquely high. Unlike sanded paper where erasing often just smears the grit, Pastelmat allows for relatively clean erasing using a melamine sponge (like a Magic Eraser) or a battery-operated eraser, making it very forgiving.Weights & Formats:Standard Sheets/Pads: 360 gsm (140 lb).Mounted Boards: A rigid 1.8mm board version for artists who work large-scale and want to avoid any potential for the card to curl during wet underpaintings.Working Techniques & Performance NotesFinger Blending: Unlike sanded papers (which act like 400-grit sandpaper on your skin), Pastelmat is gentle on fingertips. You can blend extensively without physical discomfort.Fine Details: This is the gold standard for pastel pencils. The smooth, velvety tooth allows for razor-sharp lines and whiskers that stay crisp, whereas coarser sanded papers can make fine lines appear "jagged."The "Grainy" Phase: Beginners often find their first layer looks "grainy" or "pitted."Technical Fix: You must push the pigment into the fibers. Once the initial "pore" is filled, subsequent layers glide on with a buttery, painterly consistency.Handling Note: The surface is sensitive to body oils. It is highly recommended to use the provided glassine interleaving (found in the pads) under your hand while working to prevent oil spots from creating "resists" on the paper.

Fabriano (Italy, est. 1264) is one of the oldest paper mills in the world. Their pastel papers are defined by a distinct European sensibility—favoring traditional "laid" and "felt" textures over the gritty, sandpaper-like surfaces of modern American brands. They are best known for high cotton content and a massive range of sophisticated, lightfast colors.1. Fabriano Tiziano (The Popular Choice)The versatile, high-cotton workhorse for students and professionals.Composition: 40% cotton / 60% alpha-cellulose.Texture: Felt finish. It has a soft, woven, "toothy" surface that isn't as linear as a laid paper. It feels like a very fine fabric.Weight: 160 gsm.Color Range: 40 colors. Available in a stunning array of subtle Italian tones (from "Billiard Green" to "Sahara").Behavior: The high cotton content makes it soft and receptive. It holds multiple layers of soft pastel or charcoal without getting slick too quickly. It is also sized to handle light wet media (ink or gouache washes).Best For: General pastel drawing, charcoal, and mixed media studies.2. Fabriano Ingres (The Classic Laid Paper)The traditional choice for old-master style drawing.Composition: 100% alpha-cellulose.Texture: Laid Finish. This paper features a distinctive "grid" of horizontal and vertical lines (chain lines) created by the paper-making mould. It has a high-relief grain that catches pastel and charcoal in a linear pattern.Weight: 160 gsm.Behavior: Very toothy on one side and slightly smoother on the reverse. It is designed for expressive, rhythmic strokes.Best For: Classical portraiture, life drawing, and artists who want the "laid" texture to be visible in their finished work.3. Fabriano Roma (The Luxury Handmade Paper)The pinnacle of Fabriano's craftsmanship.Composition: 100% cotton.Texture: Handmade laid. Each sheet is hand-rolled with four deckled (torn-look) edges. It features the famous "She-Wolf" watermark.Weight: 130 gsm.Behavior: It is incredibly soft and flexible due to its long cotton fibers. It feels organic and "alive" under the hand. Because it is handmade, every sheet has a slightly unique personality.Best For: Deluxe editions, museum-quality commissions, and high-end calligraphy.4. Fabriano Cromia (The Heavy-Duty Surface)A newer, heavier paper for aggressive layering and mixed media.Composition: 50% cotton / 50% alpha-cellulose.Texture: Cold press grain. Unlike the felt finish of Tiziano, Cromia feels like a traditional cold-pressed watercolor paper. It has a soft feel but a deep "pit" to the tooth.Weight: 220 gsm (significantly thicker than Tiziano).Behavior: Designed with "wet strength." It can handle heavy water washes, underpainting, and aggressive erasure without pilling or tearing.Best For: Mixed media pastel pieces that start with an acrylic or watercolor wash.5. Specialty Pastel OptionsFabriano Murillo:A very heavy (360 gsm) cardstock with a "wove" (smooth but slightly textured) surface. It is exceptionally rigid and often used as a mounting board or for heavy impasto oil pastel work.Fabriano Black Black:A 300 gsm deep black cardstock. It is smooth and uncoated, making it a favorite for "neon" or high-contrast pastel pencil work where the black background needs to be perfectly flat and intense.6. Comparison: Tiziano vs. Ingres vs. CromiaTexture: Tiziano is felt (woven); Ingres is laid (Llnear); Cromia is grainy (watercolor-like).Weight: Tiziano and Ingres are standard (160 gsm); Cromia is heavy (220 gsm).Cotton Content: Ingres has 0% (alpha-cellulose); Tiziano has 40%; Cromia has 50%; Roma is 100%.Best Use: Tiziano is for all-around art; Ingres is for classical sketches; Cromia is for mixed media.

Hahnemühle (Germany, est. 1584) is one of the oldest paper mills in the world. In the pastel community, they are known for high-end, archival surfaces that range from traditional academic "Laid" papers to their world-famous, specialty "Velour" surface. They focus on archival integrity—all their pastel papers are acid-free and highly resistant to aging.1. Product LinesPastel Velour The "Animal" Paper: This is Hahnemühle’s most famous pastel product. It features a 260 gsm paper base with a lush, velvety flocking applied to the surface.Texture: Furry / velvet. It feels like soft material or the lining of a jewelry box.Behavior: It "grabs" the pastel pigment and holds it deep in the fibers, creating a soft, hazy look. It is widely considered the best paper for painting fur, hair, and soft skin tones.Warning: No water. Getting Velour wet flattens the fibers and ruins the surface. It is also very difficult to erase, so you must plan your drawing carefully.Ingres PastelThe Academic Standard: Part of their "Collection" line, this is a premium 100 gsm paper with a classic "Laid" finish.Texture: Fine ridges. It has a visible grid of fine parallel lines (ribbed) and a slightly rough surface.Behavior: It allows for crisp, precise marks and is excellent for academic figure drawing and architecture. It does not take many layers; if you apply too much pastel, the pigment will slide off the ridges.Weight: Very lightweight (100 gsm), so it is best used in pads or taped to a board.Hahnemühle LanacolourThe Multi-Media Choice: Often grouped with their pastel range, this 160 gsm paper has a high cotton content (usually 45%).Texture: Grainy / irregular. It has a more natural, dimpled texture compared to the strict grid of the Ingres paper.Behavior: Because it is heavier and has cotton, it is more robust. It can take light blending and a few more layers than Ingres.Colors: Available in a huge range of colors (up to 30 shades).Sketch/Pastel (Dessin)The Practice Paper: A 130 gsm or 150 gsm natural white paper with a fine grain.Behavior: This is a dry media paper. It is smoother than Ingres or Velour and is designed for quick sketches with hard pastels, charcoal, or pencils. It is the budget-friendly choice for students.2. Key CharacteristicsArchival Quality: All Hahnemühle papers are vegan, acid-free, and age-resistant. This is their main selling point over budget school brands.The "Tooth" Difference: Unlike "sanded" papers (like Uart or Pastelmat) which feel like sandpaper, Hahnemühle papers are soft. They are designed for artists who prefer to blend with their fingers without losing their fingerprints.Color Range: Hahnemühle is famous for its sophisticated "Grey-Scale" and "Earth" sets. Their pads often come in "9 Colors" assortments that are perfectly curated for portraits or landscapes.3. Comparison: Velour vs. Ingres vs. LanacolourTexture: Velour is velvety/furry; Ingres is ribbed/lined; Lanacolour is grained/dimpled.Weight: Velour is the heaviest (260 gsm); Lanacolour is medium (160 gsm); Ingres is very light (100 gsm).Layering: Velour takes many layers (the fibers hold a lot of dust); Lanacolour takes medium layers; Ingres takes very few layers before it gets "full."Best Subject: Velour is for animals & portraits; Ingres is for architecture & life drawing; Lanacolour is for mixed media & general art.Fixative: Velour rarely needs fixative because the fibers trap the dust; Ingres and Lanacolour usually require fixative to prevent smudging.4. Summary ChecklistPastel Velour: 260 gsm / Velvet surface / Best for fur & hair / Do not get it wet.Ingres Pastel: 100 gsm / Ribbed texture / Best for fine detail & sketches / Archival.Lanacolour: 160 gsm / Grainy texture / 45% cotton / Best for layering & color choice.Sketch/Pastel: 130 gsm / Fine grain / Budget choice / Best for quick studies.Historical Note: PastellFix (a grippy, rubbery-textured paper) was discontinued a few years ago; if you find it, it is rare old stock.

Sennelier (France) doesn't just make the softest pastels in the world; they also manufacture the specific surfaces required to hold that much pigment. While most brands focus on "Sanded" paper, Sennelier's flagship product uses natural cork, giving it a unique organic feel that is softer on the fingertips than industrial sandpaper.1. Sennelier La Carte Pastel CardThe pro choice for soft, painterly layering. Do not confuse this with standard paper; it is a stiff board.Surface Chemistry: Natural cork powder.Finely ground cork is applied to a pH-neutral board. This creates a soft, "velvety" grit that is much less abrasive than the volcanic stone used on papers like UART.The "Water" Warning:NOT water-resistant. The binder used to stick the cork to the board is water-soluble. If a single drop of water (or sweat) hits the surface, the coating will dissolve and peel off, leaving a permanent bald spot.Best For: Dry techniques only. Never use for wet underpaintings.Weight: Stiff 200 lb (360 gsm) cardstock. It is rigid and does not require mounting.Layering: Can hold an incredible amount of pigment—up to 25 layers of soft pastel—drastically reducing the need for fixative.Colors: Available in 14 organic shades (Sienna, Sand, Charcoal, etc.).2. Sennelier Pastel Card "Mixed Media" The modern, waterproof version of La Carte released in late 2024.The Upgrade: This looks and feels like the original La Carte but is completely waterproof.Surface: Still uses the cork powder formula, but with a new binder that resists water and alcohol.Best For: Wet underpaintings. You can now use acrylic inks, watercolors, or alcohol washes on a Sennelier card before adding pastels on top.Weight: Slightly lighter at 190 lb (410 gsm) but remains a stiff card format.Identification: Look for the "Mixed Media" label on the pad or sheet to distinguish it from the original water-sensitive version.3. Sennelier Velvet PaperA specialty surface for delicate, light-touch work.Texture: Extremely soft, sumptuously fuzzy texture.Weight: 130 gsm (60 lb). This is a thin paper, not a card.Behavior: It grabs the pastel differently than the cork card. It is designed for subtle blending and a very soft, unfocused look.Colors: Limited (usually available in Grey, Beige, and Black).4. Sennelier "L'Esprit du Pastel" Felt PaperThe traditional sketching option.Texture: Felt / Fibrous.Weight: 130 gsm.Behavior: This paper has a noticeable grain (tooth) that is felt-like rather than sandy. It is designed to emulate the historic "Spirit of Pastel" look of the 18th century.Protection: Usually sold in pads where each sheet is interleaved with Glassine paper to protect the delicate dust from smudging.5. Comparison: Original La Carte vs. Mixed MediaSurface: Original is cork-based (very soft grit); Mixed Media is cork-based (slightly smoother).Water Sensitivity: Original dissolves with water; Mixed Media is waterproof.Technique: Original is for dry pastel only; Mixed Media is for watercolor/ink underpaintings + pastel.Stiffness: Both are stiff cards that do not buckle or warp under normal use.Summary ChecklistLa Carte Pastel Card: Natural cork / Stiff card / Ruined by water / Best for animal fur & portraits.Mixed Media Card: Natural cork / Waterproof / Supports alcohol & ink / Best for modern mixed media.Velvet Paper: Sumptuous fuzzy texture / Thin / Best for soft blending.Felt Paper: Fiber tooth / Acid-free / Glassine interleaved / Best for traditional sketches.

Strathmore (USA) is one of the most respected names in paper, using a tiered "Series" system (300 to 500) to help artists choose between practice and professional grades. For pastels, they offer several specialized surfaces ranging from traditional "Laid" textures to fiber-enhanced mixed media sheets.1. The Series System300 Series (Better/yellow cover): Student grade. Made from alpha-cellulose (wood pulp). It is economical and designed for practice and quick studies.400 Series (Best/brown cover): Intermediate/Advanced grade. Heavier and more durable than the 300 series. Designed for finished artwork.500 Series (Premium/pink cover): Professional grade. Made with 100% cotton fiber. It is archival, acid-free, and designed to last for centuries.2. Strathmore Pastel Paper (400 Series)The workhorse for pastel artists.Weight: 80 lb (118 gsm).Texture: Pebbled/Textured.Unlike the "lines" of a charcoal paper, this has a random, luxurious texture that holds multiple layers of soft pastel or oil pastel.Colors: Available in pads with a curated assortment of six subtle tints (e.g., Moonstone, Desert Rose, Flannel White).Best For: Soft pastels, hard pastels, and oil pastels. The variety of tinted backgrounds helps establish mid-tones instantly.3. Strathmore Charcoal Paper (300 & 500 Series)The classic "Laid" finish.The "Laid" Texture: This paper has a visible pattern of parallel lines (resembling the screen used in traditional papermaking). This grid creates a toothy surface that grabs charcoal and pastel particles.300 Series Charcoal (Yellow):Weight: 64 lb (95 gsm).Surface: Traditional laid finish.Best For: Intermediate students practicing shading and value studies with charcoal or hard pastels.500 Series Charcoal (Pink):Composition: 100% cotton.The Difference: Extremely strong and resilient. It can handle heavy erasing, "lifting" of color, and multiple layers without the surface pilling or tearing.Colors: Available in over 20 rich colors (sold as individual sheets) or as pads in white and assorted tints.Best For: Professional charcoal drawings and soft pastel pieces requiring high durability and archival status.4. Artagain® (400 Series)The fiber-enhanced alternative.Weight: 60 lb (160 gsm).Surface: Vellum finish (velvety).This paper is 100% recycled and contains fiber inclusions that give it a "heathered" look. It is much smoother than the standard pastel or charcoal papers.Best For: Soft pastels, charcoal, and colored pencil. Because it is less toothy, it is ideal for "painterly" styles where you want the paper color to peek through the strokes.Colors: Famously available in Coal Black, making it a favorite for high-contrast white charcoal or neon pastel work.5. Comparison: Pastel vs. Charcoal vs. ArtagainTexture: Charcoal Paper has a distinct "Laid" (lined) pattern; Pastel Paper has a random "pebbled" texture; Artagain is a smooth, velvety vellum.Fiber: 500 Series is 100% cotton; 400/300 Series are wood pulp/cellulose; Artagain is 100% recycled fiber-enhanced.Archival: Only the 500 Series is truly professional-archival (cotton). The 400/300 are acid-free but may degrade faster over long periods.Best Use: Use Charcoal Paper for technical shading; Pastel Paper for layered color paintings; Artagain for smooth, graphic illustrations.Summary Checklist400 Series Pastel: Pebbled surface / 80 lb / Assorted tints / Best for layering soft pastels.500 Series Charcoal: Laid pattern / 100% Cotton / Archival / Best for professional charcoal.Artagain: Smooth Vellum / Recycled / Black sheets available / Best for high-contrast sketching.

UART (USA) is considered an industry standard for sanded pastel paper. Unlike traditional textured papers (which use a honeycomb or felt pattern), UART uses a consistent, grit-based surface similar to fine industrial sandpaper. It is highly prized by professional pastelists for its ability to hold an incredible number of layers and its extreme durability under wet media.1. The Grit System (Texture Grades)UART is unique in offering seven distinct grits. Lower numbers are coarser; higher numbers are finer.240 to 320 Grit (Coarse): Texture: Very rough, akin to heavy-duty sandpaper.Behavior: Designed for maximum layering and heavy impasto techniques. It eats through soft pastels quickly but allows for a massive amount of pigment build-up.400 Grit (The "Standard"): The Popular Choice: This is the most widely used grade. It offers the perfect balance—enough tooth for dozens of layers, but smooth enough for sketching. Most beginners and pros start here.500 to 600 Grit (Medium-Fine): Texture: Noticeably smoother to the touch.Behavior: Popular for portraiture and animal fur where you need to render fine details without the "sand" texture showing through the pigment.800 Grit (Extra Fine): The Detailer: The smoothest sanded surface available. It feels almost like velvet.Best For: Detailed colored pencil work and ultra-fine pastel renderings. It cannot hold as many heavy layers as the 400 grit, but it is the kindest to your fingertips.2. Color & Format OptionsColor Palette:Original (Tan/Beige): A neutral, warm background that is easy to cover or leave showing in landscapes.Dark (Charcoal/Black): Designed to make colors pop. Note that the 400/500 Dark is a deep black, while the 800 Dark tends to look more like a dark charcoal due to the fineness of the grit.Format Varieties:Standard Sheets: Flexible and easy to cut.Mounted Boards (Premium): The paper is factory-mounted on Sintra (a lightweight, rigid PVC board). These are 1/8” thick and will never buckle, making them the gold standard for plein air painting and heavy wet washes.Pads & Rolls: Available in 10-sheet pads or large rolls for mural-sized work.3. Key Characteristics & PerformanceWet Media Compatibility:The "Indestructible" Surface: Unlike Sennelier Pastel Card (which ruins if wet) or Canson Mi-Teintes (which buckles), UART is completely waterproof and solvent-proof.Underpainting: You can use water, alcohol, mineral spirits, or turpentine to wash your first layer of pastel into a painterly base.Archival Quality:PH neutral, acid-free, and lightfast. It is a museum-grade surface that will not yellow or degrade over time.Erasability:Because the grit is so tough, you can erase layers or even use a stiff brush to "scrub" pigment off to start an area over without damaging the paper's tooth.4. Comparison: UART vs. Other Sanded PapersVs. Pastelmat: Pastelmat is velvety and soft on fingers, whereas UART is gritty and feels like sandpaper. UART can usually hold more layers of hard pastel, while Pastelmat is better for blending with fingers.Vs. Sennelier Pastel Card: Sennelier uses a vegetable-based grit that cannot get wet. UART is much more versatile because it handles any liquid underpainting.Vs. Art Spectrum Colourfix: Colourfix has a visible "screen" texture; UART is a random, natural-looking grit.5. Summary ChecklistTexture: Sanded grit (240 to 800).Wet Media: Alcohol, water, and oil safe.Colors: Tan (Original) and Charcoal (Dark).Mounted Option: Available on Sintra Board (No buckling).Best For: Professional pastelists, heavy layering, and wet underpaintings.
