TL;DR: Make porcelain vases by mixing porcelain clay, shaping it on a potter’s wheel or with hand-building methods, then firing it twice—once for bisque and once after glazing. This beginner tutorial walks you through clay preparation, forming, drying, glazing, and kiln firing to create a durable, glossy porcelain vase.
Step 1: Gather Materials and Prepare Your Clay
Porcelain clay is finer, whiter, and more translucent than stoneware, but it’s also less forgiving. You’ll need porcelain clay (sold as “porcelain” or “cone 6 porcelain”), a potter’s wheel or hand-building tools, a wire clay cutter, a sponge, water, glaze, and access to a kiln. Wedge the clay thoroughly to remove air bubbles—this prevents explosions during firing. Porcelain benefits from a firm, well-wedged consistency; if it’s too wet, let it dry on a plaster bat for 20 minutes.

Step 2: Shape the Vase
Center the clay on your wheel. Open a hole in the middle, then pull the walls upward slowly. Porcelain has low plasticity, so use less water than with stoneware and keep your hands steady. Aim for even walls about 1/4 inch thick. If hand-building, use the pinch or coil method: pinch a bowl shape, then add coils to build height, smoothing each join with a rib tool. For a classic vase silhouette, flare the rim outward and narrow the neck slightly.
Step 3: Dry and Bisque Fire
Let the vase dry slowly under plastic for 2–3 days to prevent cracking. Then air-dry until bone-dry (no coolness to the touch). Bisque fire to cone 06 (about 1830°F). This hardens the vase without melting it.
Step 4: Glaze and Glaze Fire
Dip or brush on a food-safe porcelain glaze. Wipe the bottom clean to avoid sticking to the kiln shelf. Glaze fire to cone 6 (about 2230°F). Porcelain becomes vitrified and translucent at this temperature.
Tips for Beginners
Practice centering with cheaper stoneware first. Keep porcelain covered when not working. If cracks appear, fill them with porcelain slip before bisque firing. Always test glaze on a small tile.
FAQ
Q: Can I make a porcelain vase without a potter’s wheel?
A: Yes. Use pinch, coil, or slab hand-building methods. Porcelain slabs work well for angular vases if you let them stiffen slightly before joining.
Q: Why did my porcelain vase crack during firing?
A: Cracks usually come from uneven wall thickness, trapped air bubbles, or firing too fast. Wedge thoroughly, dry slowly, and bisque fire on a slow ramp.
Q: What glaze looks best on a porcelain vase?
A: Celadon, clear, and soft white glazes highlight porcelain’s translucency. Avoid thick, opaque glazes that hide the clay body.
