TL;DR: Creating a porcelain figurine involves casting liquid slip in a mold, cleaning the greenware, firing it at high temperature, and applying glaze or china paint for a finished look. With patience and the right tools, you can produce a delicate sculpture ready for display.
Step 1: Gather Materials and Prepare the Workspace
Collect porcelain slip (casting clay), plaster molds, a fettling knife, sponges, a kiln, and china paints or glaze. Work on a clean, dust-free surface, as porcelain is unforgiving of grit. Keep water nearby but avoid soaking the mold; damp plaster ruins castings.

Step 2: Cast the Figurine in the Mold
Stir the slip gently to remove bubbles, then pour it into the mold in one steady stream. Let it sit until a 3–5 mm wall forms, pour out the excess, and allow the cast to firm up. Unmold carefully once the piece releases from the plaster without tearing.
Step 3: Clean and Refine the Greenware
While the porcelain is still leather-hard, trim seams with a fettling knife and smooth edges with a damp sponge. Hollow out thick areas and attach small details with slip. Handle the piece minimally to avoid fingerprints and distortion.
Step 4: Bisque Fire the Sculpture
Let the figurine dry completely for several days, then fire it in a kiln to around 1,260°C (cone 8–10). Slow the ramp to prevent cracking. The result is a porous, white bisque body ready for decoration.
Step 5: Glaze or China Paint
Apply porcelain glaze by dipping or brushing, wiping the base clean. For detailed figurines, use china paints applied in thin layers, firing each layer at a lower temperature. Build color gradually rather than in one heavy coat.
Step 6: Final Firing and Inspection
Fire the glazed piece according to the glaze manufacturer’s schedule. Inspect for pinholes, crazing, or uneven color, and touch up with overglaze if needed. Let the sculpture cool slowly to avoid thermal shock.
Tips for Better Results
Use distilled water for slip consistency, keep molds dry between castings, and record every firing. Porcelain shrinks roughly 12–15%, so plan sizes accordingly. Always test new glazes on small tiles before applying them to a finished figurine.
FAQ
Q: Can I make porcelain figurines without a kiln?
A: No. Porcelain requires high-temperature firing to vitrify; air-dry clay is a different material and will not produce true porcelain.
Q: Why do my porcelain sculptures crack during firing?
A: Cracking usually comes from uneven wall thickness, trapped moisture, or firing too fast. Dry pieces fully and use a slow ramp schedule.
Q: What is the difference between glaze and china paint on figurines?
A: Glaze forms a glassy waterproof surface in a high fire, while china paint is an overglaze decoration fired at lower temperatures for fine detail and color.
