TL;DR: To create a porcelain figurine, mix porcelain slip or clay, shape it using hand-building or mold techniques, then fire and glaze it for a durable finish. Follow the steps below to craft detailed sculptures with proper drying, firing, and finishing techniques.
Step 1: Gather Materials and Prepare Your Workspace
You will need porcelain clay or slip, sculpting tools, a sponge, water, a turntable, and a kiln. Cover your work surface with a non-stick mat. Porcelain is delicate and dries quickly, so keep a spray bottle of water nearby to maintain moisture.

Step 2: Design and Sketch Your Figurine
Draw your figurine from multiple angles—front, side, and back. Porcelain shrinks about 15% during firing, so plan proportions accordingly. Simple, flowing shapes work best for beginners; avoid thin, unsupported appendages.
Step 3: Form the Basic Shape
Condition the porcelain clay by wedging it to remove air bubbles. Build the core using the pinch or coil method, or pour slip into a plaster mold for consistency. Attach limbs and head using slip (clay mixed with water) as a glue. Score both surfaces before joining to create a strong bond.
Step 4: Refine Details and Smooth Surfaces
Use loop tools and wooden sculpting sticks to carve facial features, drapery, or texture. Smooth rough areas with a damp sponge. For fine details like fingers or hair, add small coils of porcelain. Keep the piece covered with plastic when not working to prevent cracking.
Step 5: Dry Slowly and Completely
Air-dry your figurine for several days in a cool, draft-free area. Porcelain is prone to warping if dried too fast. Place it on a turntable and rotate occasionally. Once bone-dry (no coolness to the touch), it is ready for the first firing.
Step 6: Bisque Fire and Glaze
Bisque fire at cone 06–04 (about 1828–1945°F). After cooling, apply porcelain glaze by dipping, brushing, or spraying. Wipe the base clean to prevent sticking. Then fire again at cone 6–10 (about 2232–2380°F) for a glossy, durable finish.
Tips for Success
Work in small sections and keep your hands clean. If a crack forms before firing, repair it with slip and let it dry again. Always test your kiln schedule on scrap pieces. For complex figurines, fire them on a bed of alumina hydrate to prevent sagging.
FAQ
Q: Can I use air-dry clay instead of porcelain for figurines?
A: No, air-dry clay lacks the translucency, strength, and glass-like finish of fired porcelain. It also cannot be glazed or fired in a kiln.
Q: How do I prevent my porcelain figurine from exploding in the kiln?
A: Ensure the piece is completely bone-dry before bisque firing, and increase the kiln temperature slowly during the first stage to release any remaining moisture.
Q: What is the best way to attach delicate parts like fingers or tails?
A: Use a thick slip made from the same porcelain body, score both surfaces, press firmly, and reinforce the joint with a tiny coil of clay. Let it dry slowly under plastic.
