Introduction
One of the most common questions I receive from clients and fellow hobbyists is, “What is the best glue to repair ceramic?” While it may seem like a simple question, the answer is nuanced. The type of glue used can significantly affect the durability, appearance, and longevity of a ceramic repair.
Why Not Just Use Superglue?
Superglue might seem like an easy solution, but it’s far from ideal for most ceramic repairs. Over time, superglue tends to discolour and can break down, leading to a less-than-perfect restoration.
Epoxy Resins: The Gold Standard
For most ceramic repairs, epoxy resins offer the best performance. They come in various setting times and can be colour-matched to the ceramic piece, making the repair less visible.
Fast-Setting vs. Slow-Setting
Fast-setting epoxies can bind pieces quickly, but they’re generally not as durable as their slow-setting counterparts, which offer more flexibility and can withstand more stress over time.
Colour-Matching
Some specialized epoxies can be tinted to match the ceramic piece you’re working on, making the repair less noticeable.
What About Museum-Quality Repairs?
For museum-quality restorations, a different set of adhesives may be used that prioritize preservation over aesthetics. These adhesives are often reversible, allowing future restorers to remove them easily.
Safety First
Regardless of which glue you choose, always read the manufacturer’s instructions and safety warnings. Work in a well-ventilated area and use appropriate safety gear like gloves and eye protection.
When to Seek Professional Help
If you’re unsure which adhesive to use or if you have a particularly valuable or sentimental piece, it’s always best to consult with a professional restorer. The investment in professional restoration often outweighs the cost of a failed DIY repair, both emotionally and financially.
Conclusion
Choosing the best glue for ceramic repairs involves considering various factors, including the type of ceramic, the nature of the break, and the intended use of the repaired piece. While epoxy resins are generally the best choice for most projects, some situations might require different adhesives.
If you’re in doubt, feel free to reach out for a consultation. We’re here to help you make the best choices for your treasured ceramics.
Hi,
Are there certain glues that are better at withstanding heat? We have a beautiful ceramic kettle for boiling water. It has a small chip in it that I’d like to glue back on and know that it can withstand heat to the best of its ability.
Yours with curiosity

Hello Phil,
Thank you for reaching out with your question. It’s great to hear that you’re looking to restore your ceramic kettle. Here is your response from Rob:
When it comes to repairing ceramics that will be exposed to heat, especially items like a kettle, the choice of adhesive is crucial.
For high-heat environments, I recommend looking for adhesives specifically designed to withstand high temperatures. These are often termed as “high-temperature” or “heat-resistant” adhesives. One of the most suitable types of glue for your needs would be a high-temperature epoxy resin. These epoxies are engineered to maintain their bond strength and stability up to certain temperatures, often as high as 315°C (600°F) in some products.
However, it’s important to note that while these adhesives can withstand heat, most glued items, particularly those that come into direct contact with food or drink, should not be used for their original purpose again. The integrity of the repair might not be guaranteed under all conditions, especially where boiling water is involved. This can pose a safety risk if the repair fails while the kettle is in use.
Given the nature of your item—a kettle for boiling water—I’d advise against repairing it for continued use in boiling water due to safety concerns. It might be better to repurpose this kettle as a decorative item or for cold storage only.
If you decide to go ahead with the repair for non-heat-related use, please ensure you use the adhesive according to the manufacturer’s instructions and allow ample curing time for the best result.
I hope this answers your question, Phil. If you have any more queries or need further assistance, feel free to reach out.
Best wishes, Rob!
I ordered a vintage black panther tv clock and it delivered broken in many pieces. How can I repair…….i have pictures.
It’s a 10-to-14-step process: meticulous cleaning, trial assembly, precision gluing, etc. Miss a step and the whole job unravels.
I Rob,
I have six china cups and saucers from my grandparents which I think are about 100 years old, four saucers and two cups are broken could you tell me which would be the best glue or epoxy resin to use.
Hoping you can be of help.
Dave.
I use conservation-grade epoxies reserved for professional restorers. They cure clear, remain stable for decades, and won’t yellow the glaze—products are not generally available retail, sorry.
