TL;DR: To sculpt porcelain figurines, wedge your clay, shape the body using pinch and coil methods, then hollow it out and refine details before bisque firing. Finish with glaze and a second firing to achieve a durable, glossy sculpture.
Step 1: Gather Materials
Porcelain clay is prized for its smooth, translucent quality, but it demands care. You will need porcelain clay (often labeled “cone 6” or “cone 10”), a wire clay cutter, a wooden sculpting tool, a sponge, a small bowl of water, and a needle tool. Work on a clean, non-porous surface like a glass mat or canvas board.

Step 2: Wedge and Condition the Clay
Porcelain is stiff and prone to air bubbles. Slice the clay into thin layers, press them back together, and knead firmly but quickly. Avoid overworking—porcelain absorbs moisture from your hands and can become sticky. Stop when the clay feels even and soft, like firm cookie dough.
Step 3: Build the Core Shape
Roll a walnut-sized ball of clay. Press your thumb into the center to create a small bowl, then pinch the walls outward and upward to form a rough torso or animal body. For limbs, roll thin coils and attach them with slip (clay mixed with water). Score both surfaces before joining.
Step 4: Hollow and Refine
Porcelain figurines thicker than one inch will explode in the kiln. Use a loop tool to scoop out the inside of the main body, leaving walls about half an inch thick. Then smooth the surface with a damp sponge. Carve eyes, folds, or fur with a needle tool. Keep details shallow—porcelain tends to slump.
Step 5: Dry and Fire
Air-dry the figurine slowly under a plastic tent for two days. Then bisque fire at cone 06 (about 1828°F). After cooling, apply porcelain glaze with a soft brush. Fire again at cone 6 (about 2232°F). Let the kiln cool completely before opening.
FAQ
Q: Can I use air-dry clay instead of porcelain?
A: Yes, but air-dry clay lacks porcelain’s translucence and strength. For true figurines, use kiln-fired porcelain.
Q: Why did my figurine crack during drying?
A: Uneven thickness or fast drying causes cracks. Always hollow the core and dry slowly under plastic.
Q: How do I prevent porcelain from warping in the kiln?
A: Support thin parts with kiln stilts or fire on a bed of alumina hydrate. Keep forms compact and avoid thin, unsupported limbs.
