Slab building with porcelain is a rewarding and versatile ceramic technique that allows beginners to create everything from functional tableware to sculptural art. This comprehensive guide will walk you through every step, from preparing your porcelain clay to assembling, decorating, and firing your first slab-built pieces. Along the way, you'll find helpful images, video tutorials, and expert tips to ensure your success.
Slab building is a handbuilding technique in ceramics where flat sheets of clay are cut and assembled to form three-dimensional objects. When using porcelain, this method offers the potential for refined, delicate, and translucent works that are both functional and beautiful. Unlike wheel throwing, slab building is accessible to beginners and allows for a wide range of creative expression[7][13].
Before you begin slab building with porcelain, gather the following essentials:
- Porcelain clay (choose a beginner-friendly body)
- Rolling pin or slab roller
- Wooden or acrylic spacers (to control slab thickness)
- Cutting tools (needle tool, fettling knife, craft knife)
- Ribs and smoothing tools
- Scoring tool (serrated rib or fork)
- Slip (porcelain clay mixed with water)
- Canvas or wooden boards (to prevent sticking)
- Molds or forms (optional, for shaping)
- Plastic wrap or damp cloths (to keep slabs moist)
- Templates or rulers (for precise shapes)
- Sponge and water container
Porcelain is prized for its whiteness, translucency, and fine texture. However, it is also more challenging than stoneware or earthenware due to:
- High shrinkage rate: Porcelain shrinks more as it dries and fires, increasing the risk of cracking.
- Quick drying: It loses moisture rapidly, so you must work efficiently and keep slabs covered.
- Delicate joins: Proper scoring and slip application are crucial for strong, seamless connections[3][5].
Despite these challenges, porcelain's beauty and versatility make it worth the effort for beginners willing to learn.
- Wedge the clay thoroughly to remove air bubbles and ensure an even consistency.
- Cut manageable pieces using a wire cutter or string.
- Keep unused clay wrapped in plastic or under a damp towel to prevent drying[1][7].
- Flatten the clay with your hands into a disc.
- Place between canvas or on a wooden board to prevent sticking.
- Use a rolling pin or slab roller to roll the clay evenly, placing spacers on each side to control thickness (typically 6–12mm for beginners).
- Flip and rotate the slab frequently to avoid warping and ensure even thickness[5][9].
> Rolling out a porcelain slab to Roll Out Porcelain Slabs
- Use templates or rulers to mark out shapes for your project (e.g., rectangles for a box, circles for a plate).
- Cut with a sharp knife or needle tool for clean edges.
- Smooth the edges with a damp sponge or rib to prevent cracking[6][9].
- Let slabs firm up to leather-hard before assembling (they should be flexible but hold their shape).
- Score the edges to be joined using a serrated rib or fork.
- Apply slip generously to the scored areas.
- Press slabs together firmly, ensuring a tight bond.
- Reinforce joints with a thin coil of clay if needed.
- Smooth seams with a rib or damp sponge for a seamless finish[3][7][9].

- Dry pieces slowly and evenly to prevent warping and cracking. Cover with plastic or use a drying tent for larger works[3][7].
- Bisque fire at a low temperature (around 900°C/1650°F).
- Glaze and fire again at the appropriate temperature for your porcelain body.

- Texture slabs before assembly using stamps, rollers, or found objects.
- Carve or incise designs when the clay is leather-hard.
- Apply colored slips or underglazes for surface decoration.
- Glaze with translucent or satin-matte glazes to highlight porcelain's natural beauty[4].
> Textured porcelain slab plate on Problems and Solutions
| Problem | Cause | Solution |
|---|---|---|
| Cracking | Uneven drying, weak joints | Dry slowly, reinforce joints, even thickness |
| Warping | Uneven thickness, fast drying | Roll evenly, flip slabs, dry under plastic |
| Weak joins | Poor scoring/slip, dry slabs | Score deeply, use plenty of slip, join damp |
| Slab slumping | Assembled too soft | Wait for leather-hard stage before assembly |

Slab building with porcelain is an accessible and creative way for beginners to explore the world of ceramics. By mastering the basics—preparing clay, rolling slabs, cutting, joining, and careful drying—you can create elegant, functional, and artistic pieces. Remember to work patiently, respect porcelain's unique properties, and don't be afraid to experiment with textures and forms. With practice, your confidence and skill will grow, opening up endless possibilities in slab-built porcelain ceramics.
Slab building with porcelain is a handbuilding technique where flat sheets of porcelain clay are cut and assembled to create three-dimensional objects, such as plates, boxes, or vases. It's ideal for geometric and architectural forms[7][13].
Porcelain dries quickly, shrinks more, and is less forgiving than stoneware or earthenware. This means you must work efficiently, keep slabs covered, and pay extra attention to joining and drying to avoid cracks and warping[3][5].
Roll slabs evenly, flip and rotate them during rolling, let them reach leather-hard before assembly, and dry finished pieces slowly under plastic or in a drying tent to prevent rapid moisture loss[3][7][9].
For beginners, slabs should be between 6mm and 12mm (1/4" to 1/2") thick. Thinner slabs are possible but require more experience to handle without breaking[7][5].
Yes! You can impress textures, carve designs, or apply colored slips and underglazes before firing. Porcelain's smooth surface is perfect for detailed decoration[4][6].
