TL;DR: Sculpt your figurine from porcelain clay, hollow it to prevent explosion, then bisque-fire, glaze, and glaze-fire for a durable, translucent finish. Mastering moisture control and slow firing cycles is the key to professional results.
Step 1: Gather Materials & Design
Use fine-grain porcelain clay (cone 6–10), sculpting tools, a sponge, and a turntable. Sketch your figurine from multiple angles. Porcelain is soft and memory-prone, so plan forms with adequate wall thickness (3–5 mm).

Step 2: Sculpt the Figurine
Build the core mass first—torso, head, limbs—using pinch or coil methods. Attach appendages with slip (clay + water) and score the joints. Keep a spray bottle handy; porcelain dries fast and cracks. Refine details with loop tools and a damp sponge. Hollow the base and torso to 1 cm wall thickness.
Step 3: Slow Dry & Bisque Fire
Dry the figurine under plastic for 3–5 days, poking tiny air holes. Then air-dry until bone-dry (no cold feel). Bisque-fire to cone 04 (1,060°C) with a slow ramp—100°C/hour up to 600°C, then 150°C/hour. This prevents steam explosions.
Step 4: Glaze Application
Dust the bisque with a soft brush. Dip or brush on porcelain glaze (celadon, clear, or stain). Keep glaze 1 mm thick; thin edges. Wipe glaze off the foot ring with a damp sponge to avoid sticking.
Step 5: Glaze Fire & Finish
Fire to cone 6 (1,220°C) or cone 10 (1,280°C) per glaze specs. Soak for 15 minutes at peak for gloss. Cool slowly. If using overglaze enamels, fire again to cone 018. Inspect for pinholes; refire if needed.
Pro Tips
• Add 2% bentonite to porcelain for plasticity. • Never handle bone-dry pieces with bare hands—oils cause glaze crawl. • Test-fire small tiles before glazing your figurine.
FAQ
Q: Why did my porcelain figurine explode in the kiln?
A: Trapped moisture or thick walls caused steam pressure. Hollow to 1 cm, dry fully, and bisque-fire slowly below 600°C.
Q: Can I use earthenware glaze on porcelain?
A: No—earthenware glazes mature at cone 06–04, too low for porcelain. Use cone 6–10 porcelain glazes for proper fit and durability.
Q: How do I fix a crack after bisque firing?
A: Fill with bisque fix (clay + frit + water), refine, then glaze-fire. For structural cracks, refire the piece with a paper-clay patch before glazing.
