TL;DR: To make porcelain figurines, you shape wet porcelain clay by hand or with molds, let it dry to leather-hard, refine details, then bisque-fire and glaze-fire it in a kiln. Master the stages of clay and use slip for joining to avoid cracks.
Materials & Preparation
Gather porcelain clay (not stoneware—it’s whiter and more translucent), a spray bottle, wooden sculpting tools, a needle tool, a soft sponge, a rolling pin, and a small bowl of slip (clay mixed with water to a yogurt consistency). Work on a plaster bat or canvas to wick moisture. Porcelain is finicky: it dries fast and warps easily. Cover unused clay with plastic.

Step 1: Form the Core Body
Start with a solid lump of clay, about the size of your fist for a 4-inch figurine. Knead it to remove air bubbles. For a standing figure, build a simple armature from wire or a wooden skewer wrapped in newspaper—this supports the weight. Press clay around the armature, shaping the torso, head, and limbs as rough cylinders. Keep thickness even (¼ inch max) to prevent cracking during firing.
Step 2: Refine to Leather-Hard
Let the piece sit uncovered for 30–60 minutes until it feels like firm cheese—not sticky, not brittle. At this leather-hard stage, you can carve details without distortion. Use a needle tool to sketch facial features, hair, or clothing folds. Add separate pieces (arms, wings, hats) by scoring both surfaces with a fork and brushing on slip. Press gently to bond. Smooth seams with a damp sponge.
Step 3: Hollow Out (If Solid)
If your figurine is solid, it will explode in the kiln. Once leather-hard, cut a small hole in the base and scoop out the interior with a loop tool until walls are ¼ inch thick. Leave an air hole if fully enclosed. For hollow-cast figurines (slip casting), skip this step—just trim the mold seam.
Step 4: Dry and Bisque Fire
Dry slowly under plastic for 3–5 days, then unwrapped for another 2 days. No moisture should feel cool to the cheek. Fire to cone 04 (1940°F) for bisque—this makes the piece porous but strong. Cool completely before handling.
Step 5: Glaze and Final Fire
Apply porcelain glaze with a brush or by dipping. Use underglazes for fine details (like eyes or roses) before a clear glaze. Wipe the bottom clean. Fire to cone 6 (2232°F) for vitrification—porcelain becomes glassy and translucent. Let cool slowly in the kiln to prevent dunting (thermal shock).
Pro Tips
Keep a spray bottle nearby—porcelain cracks if too dry. Never force-dry with a heat gun. For delicate parts like fingers, sculpt them separately, dry, and attach with thick slip before leather-hard. Test small samples first to learn your clay’s shrinkage (usually 12–15%).
FAQ
Q: Can I use air-dry clay instead of real porcelain?
A: No—air-dry clay lacks the vitrification and translucency of fired porcelain, and it won’t survive kiln temperatures. For true figurines, use high-fire porcelain clay.
Q: Why did my figurine crack during drying?
A: Cracks come from uneven drying—thick and thin sections shrink at different rates. Dry slowly under plastic, and ensure walls are uniform (¼ inch). Also, avoid joining pieces when one is too wet or too dry.
Q: How do I make a mold from an original sculpture?
A: For production, make a two-part plaster mold from your finished bisque original. Pour liquid porcelain
