TL;DR: Clean the broken edges, dry-fit the porcelain shards, then bond them with a two-part epoxy or porcelain-specific adhesive, curing fully before finishing. For missing pieces, fill with epoxy putty, sand smooth, and touch up with enamel paint matched to your vase’s glaze.
Gather Your Materials
Before touching the vase, assemble the right supplies: a two-part epoxy rated for ceramics (or a porcelain repair adhesive), epoxy putty for gaps, 400- and 800-grit wet sandpaper, acetone or isopropyl alcohol, cotton swabs, toothpicks, painter’s tape, and enamel touch-up paint. Work on a clean, well-lit surface lined with wax paper. Porcelain is fragile, so handle every shard by its edges only.

Step 1: Clean and Dry-Fit the Break
Wipe all broken edges with alcohol to remove dust and old glue residue. If the vase was repaired before, soften old adhesive with acetone and gently scrape it away with a toothpick. Then dry-fit the pieces together without glue. Note how each shard aligns, and mark subtle matching points with tiny tape tabs if the break is complex. A successful dry fit makes the final bond nearly invisible.
Step 2: Apply the Adhesive
Mix your two-part epoxy according to the package instructions. Apply it sparingly to one edge with a toothpick, not the tube, to avoid squeeze-out. Press the shard into place and hold for 30–60 seconds. Use painter’s tape to support the joint while it sets. Work on one seam at a time, letting each cure before moving to the next. Patience here prevents shifting and visible glue lines.
Step 3: Fill Missing Pieces
For chips or gaps, knead epoxy putty until uniform, then press it into the void with a toothpick. Slightly overfill the area, because putty shrinks as it cures. After 24 hours, wet-sand the patch with 400-grit, then 800-grit paper until it sits flush with the porcelain surface. Rinse and dry the vase between grits to check your progress.
Step 4: Touch Up and Finish
Match the vase’s glaze with enamel paint, applying thin coats with a fine brush. Build color gradually rather than in one heavy layer. For glossy porcelain, finish with a clear acrylic sealer once the paint dries. Let the restored vase cure for 72 hours before handling it roughly or exposing it to water.
Tips for a Better Repair
Never use super glue on porcelain; it yellows and fails under moisture. Keep repairs away from food-contact surfaces. If the vase is valuable or the break is structural, consult a professional ceramics restorer instead of risking further damage.
FAQ
Q: Can I use super glue to repair a porcelain vase?
A: No. Cyanoacrylate glue becomes brittle, yellows over time, and weakens with moisture. Use a two-part epoxy or ceramic-specific adhesive for a durable, cleaner bond.
Q: How long should I wait before using the repaired vase?
A: Let the adhesive cure 24 hours and any paint or sealer dry fully, then wait 72 hours total before handling the vase or adding water.
Q: What if a piece of my porcelain vase is missing entirely?
A: Rebuild the missing area with epoxy putty, let it cure, wet-sand it flush, and blend enamel paint to match the surrounding glaze.
