TL;DR: To make a porcelain vase, you must shape porcelain clay on a potter’s wheel or by hand-building, then bisque-fire it, glaze it, and fire it again at high temperature. This beginner tutorial walks you through each stage, from wedging the clay to the final glaze firing, so you can create a durable, elegant porcelain vase at home or in a studio.
Step 1: Prepare Your Porcelain Clay
Porcelain is a fine, dense clay that demands patience. Start with 2–3 pounds of porcelain clay. Wedge it thoroughly on a plaster bat to remove air bubbles and achieve an even moisture level. Unlike stoneware, porcelain becomes soft quickly, so work with small batches.

Step 2: Center and Open the Clay
Place the wedged clay on a potter’s wheel. Wet your hands and the wheel head. Center the clay by pressing your palms inward while the wheel spins. Once centered, use your thumbs to open a hole in the middle, leaving a ½-inch thick base. Slowly pull the walls upward, keeping them even. Aim for a vase height of 6–8 inches for a beginner.
Step 3: Shape and Refine the Vase
Use a rib tool to smooth the outside and create a gentle curve. For a classic porcelain vase, flare the neck slightly. Trim the base when the clay is leather-hard. Cover the vase with plastic to dry slowly—porcelain cracks if dried too fast.
Step 4: Bisque Fire
Once bone-dry, bisque-fire your vase to cone 06 (about 1828°F / 998°C). This hardens the clay without melting it, making it safe to glaze.
Step 5: Glaze and Glaze Fire
Apply a porcelain-appropriate glaze—celadon or clear gloss works well. Dip, pour, or brush evenly. Wipe the foot ring clean. Fire to cone 6 (2232°F / 1222°C) for a vitrified, translucent finish.
Tips for Beginners
Keep your hands wet but not dripping. Porcelain has a narrow working window; if it gets too soft, let it rest. Always test glazes on small tiles first. Expect a 20–30% shrinkage rate, so throw larger than your target size.
FAQ
Q: Can I make a porcelain vase without a potter’s wheel?
A: Yes. Use the pinch-pot or coil method, then smooth the surface with a rib tool. Hand-built porcelain vases are perfectly functional, though less symmetrical.
Q: What glaze is best for a porcelain vase?
A: A clear or translucent glaze shows off porcelain’s natural whiteness. Celadon, oxblood, and satin white are also popular and beginner-friendly.
Q: Why did my porcelain vase crack during firing?
A: Cracks usually come from uneven drying, trapped air bubbles, or firing too fast. Dry slowly under plastic and bisque-fire gently to avoid thermal shock.
