TL;DR: To sculpt a porcelain figurine, shape moist porcelain clay into your subject, hollow it, and fire it once (bisque), then apply glaze or china paint and fire again. This guide walks you through armature building, sculpting, drying, and kiln firing for durable, detailed results.
Gather Tools and Materials
You need porcelain clay (paper clay or casting slip thickened), wire for an armature, sculpting loop tools, a sponge, a needle tool, fine sandpaper, and a kiln. Porcelain shrinks 12–15% during firing, so plan proportions larger than the final piece.

Step 1: Build the Armature
Twist aluminum wire into a stick figure matching your pose. Keep it smaller than the final figure because porcelain shrinks. Wrap the wire with floral tape to help clay adhere.
Step 2: Block Out the Form
Press small porcelain balls onto the armature, building the torso, head, and limbs. Work in thin layers (no thicker than 1 inch) to prevent air pockets that cause explosions in the kiln. Blend seams with a damp sponge.
Step 3: Sculpt Details
Use loop tools to carve facial features, fabric folds, and hair. Add tiny coils for fingers and ribbons. Keep a spray bottle handy—porcelain dries fast and cracks if too dry. Wrap unused sections in plastic.
Step 4: Hollow and Dry
Once leather-hard, cut the figurine in half with a needle tool, scoop out the thick interior, and rejoin with slip (clay + water). Dry slowly under plastic for 1–2 weeks to avoid warping.
Step 5: Bisque Fire and Finish
Fire to cone 04 (1945°F). Sand smooth, then apply underglaze or china paint. Fire again to cone 06 for glaze or cone 018 for overglaze. Cool slowly to prevent thermal shock.
FAQ
Q: Why did my porcelain figurine crack during drying?
A: Uneven thickness or fast drying causes stress. Dry slowly under plastic and hollow thick areas evenly.
Q: Can I sculpt porcelain without a kiln?
A: No. Porcelain requires high-temperature firing to vitrify; air-dry clay is a different material.
Q: How do I fix a broken porcelain arm before firing?
A: Score both broken ends, apply slip, press together, and reinforce with a tiny coil. Blend with a damp brush.
