- Ceramic Adhesive:
- Epoxy resin (two-part epoxy)
- Super glue (cyanoacrylate)
- Ceramic-specific glue
- Cleaning Supplies:
- Rubbing alcohol or acetone
- Cotton swabs or cloth
- Clamping Tools:
- Clamps, rubber bands, or masking tape

Step-by-Step Guide to Gluing Ceramic Back Together
Follow these steps to ensure a strong and durable repair:
Step 1: Clean the Broken Pieces
- Wash the ceramic pieces with warm, soapy water to remove dirt and grease.
- Use rubbing alcohol or acetone to clean the edges where the adhesive will be applied. This ensures a strong bond.
Step 2: Dry the Pieces
- Allow the pieces to dry completely. Any moisture can weaken the adhesive bond.
Step 3: Sand the Edges (Optional)
- If the broken edges are rough, use fine-grit sandpaper or an emery board to smooth them. This helps the pieces fit together more precisely.
Step 4: Prepare the Adhesive
- For epoxy: Mix the resin and hardener according to the manufacturer’s instructions.
- For super glue: Ensure the nozzle is clean and ready for use.
Step 5: Apply the Adhesive
- Use a toothpick or small brush to apply a thin layer of adhesive to one of the broken edges.
- Avoid using too much glue, as excess adhesive can weaken the bond and create a mess.
Step 6: Join the Pieces
- Carefully align the broken pieces and press them together firmly.
- Hold the pieces in place for a few seconds to allow the adhesive to set.
Step 7: Secure the Pieces
- Use clamps, rubber bands, or masking tape to hold the pieces together while the adhesive cures. Ensure the pressure is even to avoid misalignment.
Step 8: Let the Adhesive Cure
- Follow the manufacturer’s instructions for curing time. Epoxy typically takes 24 hours to fully cure, while super glue sets in minutes but may require longer for maximum strength.
Step 9: Clean Up Excess Adhesive
- Once the adhesive has cured, use a razor blade or fine sandpaper to remove any excess glue.
Step 10: Test the Repair
- Gently test the repaired item to ensure it’s secure. Avoid putting too much stress on the repaired area immediately.
Types of Adhesives for Ceramic Repair
Choosing the right adhesive is crucial for a successful repair. Here are the most common options:
- Epoxy Resin:
- Pros: Extremely strong, durable, and waterproof. Ideal for functional items like dishware.
- Cons: Requires mixing and has a longer curing time.
- Super Glue (Cyanoacrylate):
- Pros: Fast-drying and easy to use. Suitable for small repairs.
- Cons: Not as strong as epoxy and may not withstand heavy use.
- Ceramic-Specific Glue:
- Pros: Designed specifically for ceramic repairs. Often heat-resistant and waterproof.
- Cons: May be more expensive than other options.
Tips for Gluing Ceramic Back Together
- Work in a Well-Ventilated Area: Adhesives can emit strong fumes, so ensure proper ventilation.
- Wear Protective Gear: Gloves and safety goggles protect your skin and eyes from adhesive and debris.
- Avoid Overloading with Adhesive: A thin, even layer of glue is more effective than a thick, messy application.
- Be Patient: Allow the adhesive to cure fully before using the repaired item.
- Test the Repair: Start with non-functional items to practice your technique before repairing valuable pieces.
Common Challenges and Solutions
1. Misaligned Pieces
- Solution: Use clamps or tape to hold the pieces in place while the adhesive cures. Double-check alignment before securing.
2. Weak Bond
- Solution: Ensure the surfaces are clean and dry before applying adhesive. Use a stronger adhesive like epoxy for heavy-duty repairs.
3. Excess Adhesive
- Solution: Wipe away excess glue immediately with a cloth or cotton swab. Once cured, use a razor blade or sandpaper to remove hardened residue.
