TL;DR: To make porcelain figurines, you sculpt fine-grained porcelain clay into your desired shape, then fire it in a kiln at high temperatures to achieve a hard, translucent finish. This beginner’s tutorial walks you through selecting materials, sculpting a simple figure, and firing it safely for a durable result.
Step 1: Gather Your Materials
You’ll need porcelain clay (preferably a smooth, white body rated for cone 6–10), sculpting tools (wooden ribs, loop tools, a needle tool), a sponge, water, and a kiln. For glazing, choose a food-safe or decorative porcelain glaze. Work on a clean, non-porous surface like glass or slate.

Step 2: Wedge and Condition the Clay
Porcelain is notoriously stiff and air-bubble-prone. Knead the clay thoroughly with your palms to remove air pockets and even out moisture. If it cracks, add a few drops of water and continue wedging. Let it rest for 10 minutes before sculpting.
Step 3: Build the Basic Form
Start with a simple figure—a seated animal or a small standing person. Pinch off a walnut-sized ball for the body. Roll smaller balls for the head and limbs. Attach pieces by scoring the contact points with a needle tool, then applying a slip (clay mixed with water). Press gently but firmly; porcelain cracks if forced.
Step 4: Refine and Smooth
Use wooden ribs to shape curves and loop tools to hollow out thick areas—porcelain thicker than ½ inch may explode in the kiln. Smooth surfaces with a damp sponge. For delicate details like fingers or ears, use a needle tool and support the piece with your free hand. Keep a spray bottle nearby; porcelain dries fast and becomes brittle.
Step 5: Dry Slowly
Place the figurine in a plastic bag, leaving it slightly open, for 3–5 days. This slow drying prevents warping. Then let it air-dry completely for another 2 days. It should feel room-temperature and look matte—any cool spots mean trapped moisture.
Step 6: Bisque Fire
Fire your figurine in a kiln at cone 06 (about 1828°F / 998°C) for the bisque stage. This hardens the clay without melting it. Let the kiln cool completely before opening—thermal shock can crack porcelain.
Step 7: Glaze and Glaze Fire
Dip or brush on porcelain glaze. Wipe the bottom clean to avoid sticking. Fire again at cone 6 (about 2232°F / 1222°C) for a glossy, translucent finish. If you prefer a matte look, use a lower-temperature glaze and fire at cone 06 again.
Tips for Beginners
• Always test-fire a small clay coil to learn your kiln’s behavior.
• Keep your hands clean—porcelain shows every smudge.
• If a piece breaks before firing, reattach with slip and let it dry fully.
• Avoid overworking thin parts; porcelain loses strength quickly.
FAQ
Q: Can I air-dry porcelain clay without a kiln?
A: No. Porcelain requires kiln firing to vitrify and become durable. Air-dried porcelain will crumble.
Q: What’s the best porcelain clay for figurines?
A: Look for a fine-grained, plastic porcelain like “Coleman” or “Helios” rated for cone 6–10. Avoid grogged porcelain for small details.
Q: How do I prevent my figurine from exploding in the kiln?
A: Ensure it is bone-dry and no thicker than ½ inch. Fire slowly at the start (under 200°F per hour) to
