TL;DR: To sculpt porcelain figurines, wedge your clay, build the form with coils or pinch methods, then hollow it before bisque firing. Finish with wet-sanding, glaze if desired, and a second firing to achieve a durable, translucent sculpture.
Step 1: Gather Materials
Use fine porcelain clay (labeled for sculpture), a wire loop tool, sponge, wooden modeling tools, and a turntable. Porcelain is softer and more elastic than stoneware, so keep water nearby to smooth cracks.

Step 2: Wedge the Clay
Knead the porcelain on a plaster bat to remove air bubbles. Air pockets cause explosions in the kiln. Wedge until the clay feels uniform, then form a ball.
Step 3: Build the Figurine Core
Pinch a hollow base or use coils for limbs. For a small figurine, start with a solid torso, then attach head and arms with slip (clay mixed with water). Score joints before pressing together.
Step 4: Refine and Hollow
Porcelain must be no thicker than 1 inch. Use a loop tool to hollow the torso from the bottom, leaving a 1/4-inch wall. Smooth surfaces with a damp sponge. Add fine details like ears or drapery with a needle tool.
Step 5: Dry Slowly
Cover the sculpture with plastic for 2–3 days. Porcelain dries fast and cracks. Once bone-dry (no cool feel), bisque fire to cone 04 (1,945°F).
Step 6: Sand and Glaze
Wet-sand bisque with 400-grit sandpaper to remove seams. Apply porcelain glaze by dipping or brushing. Wipe the base clean. Fire to cone 6 (2,232°F) for translucency.
Tips for Beginners
Keep hands clean—porcelain stains easily. Support thin limbs with wadded newspaper during drying. If a crack forms, fill it with vinegar-mixed clay.
FAQ
Q: Can I sculpt porcelain without a kiln?
A: No. Porcelain requires high-temperature firing to vitrify; air-dry clay is a substitute but not true porcelain.
Q: Why did my figurine crack during drying?
A: Uneven thickness or fast drying. Always hollow thick areas and dry under plastic for several days.
Q: How do I attach porcelain parts without them falling off?
A: Score both surfaces, apply thick slip, and press firmly. Let the joint set under plastic for 24 hours before handling.
