TL;DR: To make a porcelain figurine, wedge and shape porcelain clay into your desired form, then hollow it slightly and fire it twice—once as bisque and once after glazing. Beginners should start with small, simple shapes and use slip to join parts securely.
Step-by-Step Porcelain Sculpture Guide
1. Gather materials. You need porcelain clay (paper clay is easiest for beginners), a wooden board, sculpting tools, a sponge, water bowl, slip (clay mixed with water), and a kiln or access to one.

2. Wedge the clay. Knead porcelain to remove air bubbles. Porcelain is soft and sticky, so work on a non-porous surface and keep your hands damp, not soaked.
3. Build the core shape. For a small figurine, roll a ball for the body and attach limbs with slip. Score both surfaces, add slip, and press gently. Keep walls under 1 inch thick to avoid explosions in the kiln.
4. Refine details. Use loop tools to carve facial features, clothing folds, or fur texture. Support thin areas with your fingers. If the clay cracks, patch with slip and smooth with a damp sponge.
5. Hollow the piece. If your sculpture is thicker than 1 inch, scoop out the center from the bottom, leaving a ½-inch wall. This prevents trapped moisture from cracking the porcelain during firing.
6. Slow dry. Cover the figurine loosely with plastic for 3–5 days, then let it air-dry completely. Rushing causes warping or cracks.
7. Bisque fire. Fire to cone 04 (about 1945°F). Let the kiln cool slowly.
8. Glaze and glaze fire. Apply porcelain glaze, wipe the bottom clean, and fire to cone 6 (about 2232°F).
FAQ
Q: Can I make porcelain figurines without a kiln?
A: No. Porcelain requires high-temperature firing to vitrify. You can use air-dry clay for practice, but it is not true porcelain.
Q: Why did my porcelain sculpture crack during drying?
A: Uneven thickness or fast drying causes stress. Hollow thick areas and dry slowly under plastic.
Q: What is the best porcelain for beginners?
A: Paper porcelain clay. The paper fibers add strength and reduce cracking during handling and drying.
