Ceramics are beautiful, durable, and timeless — from decorative vases and kitchen tiles to mugs and art pieces. But even the toughest ceramic can chip, break, or crack after a fall. When that happens, one of the first questions that pops into mind is: what to use to glue ceramic?
The answer depends on what kind of ceramic you’re repairing, where it’s located, how it’s used, and what level of durability you need. Whether you’re fixing a broken coffee mug, reattaching a ceramic figurine’s arm, or restoring an antique porcelain plate, choosing the right adhesive determines whether your repair lasts days or decades.
Let’s explore everything you need to know about the best glues for ceramic, the science behind how they work, and expert techniques to make your repairs stronger and almost invisible.
Understanding Ceramics Before You Glue
Before jumping into gluing, it helps to understand what ceramic actually is. Ceramics are made by heating clay, minerals, and silica at high temperatures to create a hard, brittle, and heat-resistant surface. While extremely durable, ceramics are nonporous and smooth, which makes gluing them trickier than bonding porous materials like wood or fabric.
There are three main types of ceramics you might encounter:
- Porcelain: Fine, dense, and often used in dinnerware or collectibles.
- Stoneware: Thicker, heavier, and often used in tiles, cookware, and pottery.
- Earthenware: More porous and less durable, often found in decorative pottery or planters.
Each type requires slightly different surface preparation and adhesive choice, depending on whether you’re repairing cracks, reattaching pieces, or filling chips.
Types of Adhesives That Work on Ceramic
When you’re deciding what to use to glue ceramic, you’ll find several adhesive categories suitable for different repair jobs. The most common options include epoxy, super glue (cyanoacrylate), polyurethane-based adhesives, and specialty ceramic repair glues.
Let’s break down each type and where they shine.
1. Epoxy: The Heavy-Duty Ceramic Adhesive
If you want maximum strength and a long-lasting hold, epoxy resin is your best bet. It’s the go-to choice for ceramic repairs that need to withstand stress, heat, or moisture.
What It Is:
Epoxy is a two-part adhesive consisting of a resin and a hardener. When mixed, they create a strong chemical bond that can fill gaps and repair even the most challenging breaks.
Why It’s Great for Ceramics:
- Extremely strong and durable.
- Water-resistant (ideal for dishes, sinks, or outdoor pieces).
- Can fill gaps, not just bond flat surfaces.
- Works on glazed or unglazed ceramics.
Best For:
- Broken mugs, bowls, or dishes.
- Ceramic tiles and sinks.
- Outdoor planters and sculptures.
Application Tips:
- Clean the ceramic surface thoroughly with isopropyl alcohol.
- Mix epoxy resin and hardener according to instructions.
- Apply a thin layer to both surfaces using a toothpick or small brush.
- Join the pieces and hold or clamp them together until cured (typically 5–10 minutes).
- Allow 24 hours for full curing before use.
Pro Tip: For invisible repairs, choose clear-drying or color-matched epoxy. You can even tint epoxy with ceramic powder or paint to blend the repair seamlessly.
2. Super Glue (Cyanoacrylate): The Fast-Fix for Small Ceramic Repairs
When you need a quick, strong bond without mixing chemicals, super glue (also called cyanoacrylate) is a fantastic option. It’s perfect for small or precise repairs that don’t require heavy-duty structural strength.
What It Is:
A fast-acting adhesive that bonds instantly with most nonporous surfaces, including ceramics and porcelain.
Why It’s Great for Ceramics:
- Dries within seconds.
- Forms a strong bond for small repairs.
- Ideal for intricate or decorative items.
- Easy to use with no mixing required.
Best For:
- Ceramic figurines, art pieces, and collectibles.
- Chips or cracks in decorative tiles.
- Small home decor repairs.
Application Tips:
- Clean surfaces thoroughly.
- Apply a tiny drop (less is more with super glue).
- Press pieces together firmly for 30–60 seconds.
- Avoid touching or stressing the joint for several hours.
Pro Tip: Avoid using super glue on food-related ceramics (like plates or mugs) or surfaces that will be exposed to high heat or moisture. It can lose its bond strength and isn’t always food-safe.
3. Polyurethane-Based Glue: The Flexible Option
For repairs requiring flexibility, like outdoor ceramics or items exposed to temperature changes, polyurethane-based glues (like Gorilla Glue) are excellent. These adhesives expand slightly as they cure, filling gaps and creating a resilient, long-lasting hold.
Why It’s Great for Ceramics:
- Expands to fill gaps and cracks.
- Water-resistant once cured.
- Bonds to ceramic, metal, glass, and wood.
Best For:
- Outdoor ceramic decorations or pots.
- Ceramic attached to mixed materials (metal, glass, stone).
Application Tips:
- Dampen one surface slightly (moisture helps the glue cure).
- Apply a small amount of glue — expansion can cause overflow.
- Clamp or tape pieces together firmly.
- Allow 24 hours for a complete cure.
Pro Tip: Once cured, polyurethane glue can be sanded or painted, making it a great choice for visible or artistic repairs.
4. Ceramic and Porcelain Repair Kits: Professional-Grade Solutions
If you want a clean, polished, and nearly invisible repair, ceramic and porcelain repair kits are the most specialized choice. These kits often contain pre-mixed epoxy, fillers, colorants, and applicators designed specifically for restoring ceramics.
Why It’s Great for Ceramics:
- Designed specifically for ceramic and porcelain bonding.
- Includes color-matching materials for seamless repairs.
- Resistant to moisture, heat, and wear.
- Often food-safe once cured.
Best For:
- Porcelain sinks, tubs, or tiles.
- Antique dishware or collectibles.
- Visible cracks on high-end ceramics.
Pro Tip: These kits are especially popular for homeowners fixing bathroom tiles or porcelain bathtubs, as they can blend repairs perfectly with the original color and texture.
Preparing Ceramic Surfaces for Gluing
One of the most overlooked steps in ceramic repair is surface preparation. Because ceramics are nonporous, adhesion relies heavily on a clean, roughened surface.
Here’s how to prep like a pro:
- Clean the Surface:
Remove dirt, oils, and debris using isopropyl alcohol or warm soapy water. Dry completely. - Roughen Glossy Surfaces (Optional):
Lightly sand glossy or glazed ceramics with fine-grit sandpaper (400–600 grit) to create micro-texture for better grip. - Dry Fit the Pieces:
Before gluing, ensure all pieces fit snugly together. Mark or photograph alignment points if necessary. - Work in a Controlled Area:
Glues set fast — so keep tools, paper towels, clamps, and a steady surface ready before applying adhesive.
How to Glue Broken Ceramic Pieces Step-by-Step
Now that you know what to use to glue ceramic, here’s how to perform the actual repair from start to finish:
Step 1: Gather Materials
- Ceramic-safe adhesive (epoxy, super glue, or repair kit)
- Toothpick or fine brush
- Masking tape or clamps
- Alcohol wipes or cleaner
- Paper towels
- Gloves (to protect from skin contact)
Step 2: Clean and Dry
Wash the ceramic parts to remove any dust or grease. Let them dry completely — moisture can weaken the bond.
Step 3: Test Fit the Pieces
Dry-fit all broken parts before gluing. This step helps visualize the order of assembly and ensures alignment.
Step 4: Apply Adhesive
Use minimal glue — too much can create a messy overflow or weak joint. For small cracks, a fine-tipped applicator or toothpick offers precision. For structural repairs, apply an even coat to both surfaces.
Step 5: Press and Hold
Align the pieces and press firmly. Hold them together for the recommended set time (usually 1–2 minutes for super glue, 5–10 minutes for epoxy).
Step 6: Secure and Let Cure
Tape or clamp the pieces in place until fully cured. Avoid moving the item during this period. Even if the surface feels dry, internal bonding continues for several hours.
Step 7: Clean Excess and Finish
Once cured, gently remove any excess adhesive with a blade or fine sandpaper. For a professional finish, touch up the repair with ceramic paint, glaze, or clear sealer.
Special Considerations When Gluing Different Ceramic Types
Not all ceramics behave the same. Here’s a quick breakdown of how to handle different ceramic materials.
Porcelain
- Dense and smooth — requires strong epoxy or porcelain-specific adhesive.
- Avoid super glue for large or structural repairs.
- Use color-matched epoxy for invisible seams.
Stoneware
- Rougher and thicker — can use epoxy or polyurethane glue.
- Best for tiles, planters, or cookware.
- Can withstand heat if using high-temperature epoxy.
Earthenware
- Porous and brittle — seal with epoxy or repair kits for extra strength.
- Avoid water exposure unless sealed with a waterproof topcoat.
- Often decorative, so focus on aesthetics.
How Heat and Moisture Affect Ceramic Glue
Ceramics often face extreme environments — from hot ovens and coffee mugs to outdoor planters in the rain. That’s why choosing temperature and water-resistant adhesives is crucial.
- Heat Resistance:
Regular super glues break down above 180°F. Epoxy resins can handle up to 300°F, while high-heat variants tolerate over 500°F. - Moisture Resistance:
Kitchen and bathroom ceramics need waterproof glues. Epoxy and polyurethane excel here, while standard craft glues fail when exposed to water or steam. - Outdoor Durability:
For garden ceramics, look for UV-stable and weatherproof glues. Epoxy and polyurethane maintain their strength in fluctuating temperatures and humidity.
Making Ceramic Repairs Look Invisible
A strong bond is great, but what about aesthetics? If you want a “barely noticeable” repair, try these finishing tips:
- Use Clear or Color-Matched Epoxy: Many brands allow tinting with paint or ceramic powder.
- Apply Paint or Enamel: After curing, lightly brush matching paint over the joint.
- Buff and Polish: Use a soft cloth and ceramic-safe polish to blend shine.
- Seal for Protection: Apply a thin coat of clear gloss or glaze sealer to match the original sheen.
The result? A repair so smooth that most people won’t even notice it’s been broken.
When to Use Professional Restoration Services
If your broken ceramic has sentimental or monetary value — like heirlooms, antiques, or fine art — DIY repair might not be enough. Professional ceramic restorers use museum-grade adhesives, color-matched fillers, and UV-cured resins for invisible, long-lasting results.
They can repair complex breakages, missing fragments, or cracks in ways that preserve both structural integrity and historical value. While more expensive, this option ensures flawless results for irreplaceable items.
Sustainability and Ceramic Repair
Repairing ceramics instead of discarding them supports sustainability. Every year, millions of ceramic items end up in landfills because people assume they can’t be fixed. Using proper adhesives extends their life and reduces waste.
By learning what to use to glue ceramic, you’re not just fixing a cup or a tile — you’re practicing a modern form of the Japanese art of kintsugi, which celebrates the beauty in repaired objects. Whether you fill cracks with gold dust or invisible epoxy, each repair tells a story of renewal and care.
Frequently Asked Questions About Gluing Ceramics
1. What is the best glue to use on ceramic?
The best glue for ceramic depends on the project, but generally, two-part epoxy is the strongest and most versatile adhesive. It bonds tightly to both porous and nonporous ceramic surfaces, fills gaps, and resists water and heat. For small, delicate repairs, cyanoacrylate (super glue) works perfectly, while polyurethane-based glues perform best outdoors or on mixed materials like ceramic and metal.
2. Does super glue work on ceramic?
Yes, super glue bonds ceramic surfaces quickly and effectively, especially for light or decorative repairs. It’s ideal for fixing figurines, chipped vases, or cracked tiles. However, it’s not recommended for items exposed to moisture, high heat, or food, such as mugs or cookware, as the bond can weaken and the adhesive may not be food-safe.
3. Can you use Gorilla Glue on ceramic?
Absolutely. Gorilla Glue, particularly its epoxy and polyurethane formulations, works very well on ceramic. Gorilla Epoxy provides a strong, clear, and water-resistant bond, while the polyurethane version expands slightly to fill gaps — making it perfect for outdoor ceramics like garden pots or statues. Just be cautious with excess glue since it expands during curing.
4. Is epoxy better than super glue for ceramic?
Yes, in most cases. Epoxy creates a more durable and gap-filling bond compared to super glue, which works best for smaller, tightly fitted surfaces. Epoxy is also more heat and moisture-resistant, making it ideal for functional ceramics like cookware, sinks, or tiles that endure wear and tear. Super glue, on the other hand, offers quick convenience for minor cosmetic repairs.
5. How do I make sure glue sticks to glazed ceramic?
Glazed ceramics have a slick surface that can resist adhesives. To improve adhesion:
- Lightly sand or scuff the surface with fine-grit sandpaper.
- Clean thoroughly with isopropyl alcohol to remove oils and dust.
- Use an adhesive labeled for nonporous surfaces, such as epoxy or specialty ceramic glue.
This extra prep ensures the glue bonds tightly to the glaze.
6. Can I glue broken ceramic dishes or mugs?
You can, but it’s important to use food-safe, high-temperature epoxy and follow all curing instructions carefully. Even then, it’s safer to repair mugs and dishes for decorative purposes only, as most adhesives are not rated for direct food contact. If you need full food safety, use kiln-fired ceramic glaze instead of glue.
7. How long does ceramic glue take to dry?
Drying time varies depending on the glue type:
- Super glue: Sets in 30–60 seconds, full cure in 24 hours.
- Epoxy: Initial set in 5–10 minutes, full cure in 12–24 hours.
- Polyurethane: Begins to set in 10–15 minutes, full cure in 24 hours.
For best results, let your repair cure for a full day before using or handling the ceramic.
8. Can you glue ceramic that will be outside?
Yes. For outdoor ceramics like planters or statues, use polyurethane or marine-grade epoxy glue, which are weatherproof and UV-resistant. Apply a clear waterproof sealer over the repair to protect against fading, moisture, and temperature fluctuations.
9. What’s the best way to make a ceramic repair invisible?
For seamless results:
- Use clear-drying epoxy or one tinted to match the ceramic.
- Wipe away excess glue immediately before it hardens.
- Once cured, lightly sand the area and paint or glaze over the joint.
- Finish with a clear gloss sealant for a uniform shine.
Patience and precision are key to making cracks nearly invisible.
10. Can I put glued ceramics in the dishwasher or microwave?
Generally, no. Unless you use high-heat-resistant, waterproof epoxy that specifically states it’s safe for dishwashers or microwaves, glued ceramics should be hand-washed only. Excessive heat and moisture can weaken the adhesive over time, leading to re-cracking or separation.
11. How do I remove glue residue from ceramic?
To remove dried glue safely:
- Soak in warm, soapy water for mild adhesives.
- Use acetone or rubbing alcohol for tougher glue spots.
- For stubborn epoxy, gently scrape with a razor blade or fine sandpaper.
Always test a small, hidden area first to avoid damaging glazes or painted surfaces.
12. Can I use regular craft glue on ceramic?
No, regular craft or school glue won’t hold ceramic. These glues are water-soluble and not formulated for hard, nonporous materials. Always choose an adhesive designed for ceramics, such as epoxy, cyanoacrylate, or polyurethane.
13. Can gluing ceramic restore its original strength?
In most cases, glued ceramics will regain 80–90% of their original strength, depending on the adhesive and quality of the bond. Epoxy provides the strongest structural repairs, while super glue is suitable for lighter fixes. For high-stress areas, consider reinforcing with additional epoxy layers or fillers.
Conclusion: The Art and Science of Gluing Ceramic Right
Learning what to use to glue ceramic is about more than fixing a broken plate or mending a cracked figurine — it’s about understanding the science behind materials and the craft of restoration. Ceramics are strong yet fragile, beautiful yet unforgiving when they break. The right adhesive bridges those contradictions, giving your favorite pieces a second life.
If you’re repairing decorative items, a fast-drying super glue or ceramic repair kit may be all you need for a neat, nearly invisible finish. For functional or structural repairs, such as tiles, cookware, or outdoor ceramics, two-part epoxy reigns supreme for its durability, heat resistance, and ability to fill gaps seamlessly.
Surface preparation is just as vital as the adhesive itself. A clean, dry, and slightly roughened surface allows glue to bond tightly and last longer. After curing, seal your repair for protection and shine — or embrace the beauty of imperfection, as seen in the Japanese art of Kintsugi, where cracks are highlighted instead of hidden.
In a world that often discards what’s broken, knowing how to glue ceramic properly encourages repair over replacement. Whether you’re restoring a family heirloom, fixing a handmade mug, or saving your favorite garden pot, the right glue, care, and patience can transform something broken into something enduring.
So next time a ceramic breaks, don’t panic — grab your epoxy, prep your workspace, and trust that with the right technique, you can make it whole again. That’s not just a repair — it’s a small act of craftsmanship, sustainability, and love.
