TL;DR: Start with porcelain slip (liquid clay) poured into plaster molds, let it set, then clean, bisque-fire, glaze, and glaze-fire your figurine. This guide walks you through each step with beginner-friendly tips.
Step 1: Gather Materials
You’ll need porcelain slip, plaster molds, a pouring jug, a fettling knife, sponges, fine sandpaper, glaze, and access to a kiln. Porcelain fires at higher temperatures (around 1200–1400°C) than earthenware, so confirm your kiln can reach cone 6–10. Buy pre-made slip from ceramics suppliers to avoid mixing raw materials as a beginner.

Step 2: Pour the Slip
Secure your plaster mold with rubber bands. Stir the slip gently — don’t whip in air bubbles. Pour it steadily into the mold until full. Wait 10–20 minutes; the plaster absorbs water, forming a clay shell against the walls. Pour out the excess slip, leaving a hollow cast. Let it rest 30–60 minutes until firm enough to handle.
Step 3: Remove and Clean the Cast
Open the mold carefully. Porcelain is fragile at this “greenware” stage. Use a fettling knife to trim seam lines. Sponge smooth any rough spots with a damp sponge. For figurines with delicate fingers or wings, support them with your palm while cleaning. Let the piece dry slowly under plastic for a day, then air-dry completely — rushing causes cracks.
Step 4: Bisque Fire
Place the bone-dry figurine in the kiln with space around it. Bisque-fire to cone 06–04 (about 1000°C). This hardens the piece so you can glaze it without it dissolving. Let the kiln cool completely before opening — thermal shock can shatter porcelain.
Step 5: Glaze and Glaze Fire
Wipe dust off the bisqued sculpture. Dip, pour, or brush on porcelain glaze. Keep the bottom unglazed so it doesn’t stick to the kiln shelf. Fire again to cone 6–10 (matching your clay’s maturity). The glaze melts into a glassy finish. Cool slowly.
Tips for Beginners
Work in a dust-free area. Keep slip covered to prevent skinning. Practice on simple shapes like a small bird or egg before attempting detailed human figurines. If a piece cracks, don’t panic — porcelain is forgiving during the greenware stage; you can patch with slip.
FAQ
Q: Can I make porcelain sculptures without a kiln?
A: No — porcelain requires high-temperature firing to vitrify. You can use air-dry clay for practice, but it won’t be true porcelain.
Q: Why did my porcelain figurine crack during firing?
A: Likely uneven thickness or too-fast heating. Dry pieces slowly and ramp kiln temperature gradually.
Q: What’s the best porcelain slip for beginners?
A: A commercial cone 6 porcelain slip with good plasticizers. It casts easily and fires reliably in most studio kilns.
