TL;DR: This tutorial teaches you how to hand-build a small porcelain vase using the coil method, then bisque and glaze fire it. You will need porcelain clay, basic pottery tools, and access to a kiln—no wheel required.
Materials & Preparation
Gather porcelain clay (cone 6 or 10, depending on your kiln), a wooden rolling pin, a needle tool, a rib (metal or rubber), a sponge, a small bowl of water, and a wire cutter. Porcelain is finicky—it shrinks ~12-15% and sags easily. Work on a plaster bat or canvas cloth to prevent sticking. Wedge the clay for 5 minutes to remove air bubbles. Keep a spray bottle nearby; porcelain dries fast and cracks if too dry. Cover unused clay with plastic.

Step 1: Roll Coils
Cut the clay into four equal pieces. Roll each into a snake-like coil, about ½ inch thick and 12 inches long. Use even pressure from your palms outward—do not press down with fingers, which creates flat spots. Lay coils on a lightly damp cloth. If they dry out, mist them. For a vase with a narrow neck, make two long coils for the base and body, and one shorter coil for the neck.
Step 2: Build the Base
Take one coil and spiral it tightly into a flat disc, about 3 inches in diameter. Score the surface with a fork or needle tool, then brush on a thin layer of slip (porcelain clay mixed with water to a yogurt consistency). Press the second coil onto the base’s edge, following the spiral. Pinch the outer and inner seams together with your thumb and index finger. Smooth with a rib. Let the base rest for 10 minutes to firm up—porcelain cannot support weight when too wet.
Step 3: Stack the Walls
Continue adding coils one at a time. Score and slip each joint. As you stack, slightly stagger the seams (like brickwork) to avoid weak lines. After every two coils, use your rib inside and outside to blend the coils into a single, even wall. Keep the wall thickness to ¼ inch—thicker will crack in firing, thinner will collapse. To shape the body, press outward gently with one hand inside and the other outside. For a classic ovoid vase, bulge the middle, then taper inward.
Step 4: Form the Neck & Rim
When the body reaches 4-5 inches, stop adding coils. Let the piece dry to “leather hard” (cool, firm, but not brittle—about 1-2 hours under loose plastic). Then, score the top edge and attach the final, shorter coil for the neck. Gently squeeze and pull upward to narrow the opening. Use a needle tool to trim the rim evenly. Smooth the rim with a damp sponge. If you want a flared lip, roll a small coil, flatten it, and attach it as a collar.
Step 5: Dry, Trim & Fire
Let the vase dry slowly under plastic for 2 days, then uncovered for 2 more days. Once bone dry (no coolness on your cheek), trim the foot with a loop tool, carving out a small recessed base. Wipe dust off. Fire to bisque (cone 04) in a kiln. Then apply glaze—brush or dip using a food-safe porcelain glaze. Leave the bottom bare. Fire again to cone 6 (or your clay’s maturity). Cool slowly inside the kiln to prevent dunting.
Pro Tips for Beginners
Work slowly—porcelain punishes rushing. Always keep seams moist. Use a hair dryer on low to speed drying only for the base, never the rim. If a crack appears, fill it with thick slip and press firmly. Test a small tile of your clay first to learn shrinkage and glaze fit.
