TL;DR: This tutorial teaches you how to select, prepare, and finish porcelain home decor pieces—from vases to trinket dishes—using underglazes and clear glaze. You’ll learn the essential firing and painting steps to create durable, glossy decor that looks store-bought.
Materials & Preparation
Gather bisque-fired (already once-fired, unglazed) porcelain items like small vases, candle holders, or soap dishes. You’ll need underglaze paints, a soft brush, a clear gloss glaze, a palette, and access to a kiln (or a local ceramic studio). Clean each piece with a damp sponge to remove dust—do not use soap, as residue repels glaze. Wipe with a lint-free cloth and let dry completely for 30 minutes.

Step 1: Design & Sketch
Sketch your pattern lightly on the porcelain with a soft pencil (graphite burns off in firing). For beginners, choose geometric stripes, polka dots, or simple botanical leaves. Avoid overly intricate designs—porcelain’s smooth surface makes corrections difficult. Use painter’s tape to mask straight lines for crisp edges.
Step 2: Apply Underglaze
Apply 2–3 thin coats of underglaze with a synthetic brush, letting each coat dry for 10–15 minutes. Work from light to dark colors; underglazes appear muted before firing. For a watercolor effect, add a drop of water to thin the paint. Keep brush strokes in one direction for even coverage. Do not mix brands—firing temperatures vary.
Step 3: Clean Edges & Touch Up
Use a damp cotton swab to erase any smudges or pencil marks while the underglaze is still wet. For tiny details, use a liner brush dipped in water. Once satisfied, let the piece dry overnight—moisture trapped under glaze causes pinholes in the kiln.
Step 4: Apply Clear Glaze
Dip the entire piece into clear gloss glaze, or brush on 3 even coats, allowing 20 minutes between coats. Ensure the bottom rim is wiped clean of glaze with a sponge—otherwise it will stick to the kiln shelf. The glaze layer should be thin but uniform; thick spots will run and warp the porcelain.
Step 5: Fire & Finish
Place the piece on kiln stilts (for small items) and fire to the underglaze manufacturer’s recommended cone (usually cone 6, ~2232°F). Cool slowly inside the kiln for 8–12 hours. Once cool, inspect for gloss. If you prefer a matte look, skip the clear glaze and only fire the underglaze to cone 5. Buff with a soft cloth to remove any kiln dust.
Pro Tips for Longevity
Never place porcelain decor in the dishwasher—hand wash with mild soap. Keep pieces away from direct sunlight to prevent underglaze fading. Use felt pads under vases to avoid scratching furniture.
FAQ
Q: Can I use regular acrylic paint instead of underglaze?
A: No—acrylics burn off in the kiln and won’t fuse to porcelain. Use only ceramic-specific underglazes or overglaze enamels.
Q: What if I don’t have a kiln at home?
A: Many ceramic studios offer kiln rental or firing services for a small fee. You can paint at home, then take your bisque piece to a local studio for the glaze firing.
Q: How do I fix a drip or bubble in the clear glaze?
A: Sand the dried glaze gently with 400-grit sandpaper before firing, or add a third thinner coat. After firing, small bubbles can be buffed with a diamond polishing pad.
