How To Repair A Broken Ceramic Mug

My college mug came out the dishwasher with a crack last week. My coffee didn't gustatory modality the same out of a mug that didn't remind me of all the lectures I no longer have to attend.

Having invested an inordinate corporeality of fourth dimension scouring the cyberspace for methods to repair it, I figured I could spare other sentimental souls that try and compile a review of the all-time ways to salvage a ceramic emblem.

How To Repair A Ceramic Mug: Short respond

Hairline cracks in ceramic mugs can be repaired either by soaking them in warm milk or past gluing them with cyanoacrylate mucilage or epoxy resin

Which method you choose depends on how severe the crack is and whether you're repairing it for advent or functionality.

How To Repair A Ceramic Mug With Milk

It's not a hoax: boiling your cracked ceramics in milk really tin can seal up the cracks! (quick video below to prove you lot how)

I had to endeavor it. Since I intend on drinking coffee out of my mug this seemed similar the to the lowest degree toxic pick and I figured information technology couldn't do any damage. To my anaesthesia, information technology worked!

The method is non complicated:

• Put the mug in a bucket and cover it with milk.
• Bring information technology very gently to the boil (vigorous humid might result in more than than a hairline crack).
• Once boiling, plough it down and simmer for an hour.
• Wait for the milk to cool before extracting your repaired mug.
• Leave information technology to cure for a solar day or two earlier drinking from it again.

How Long Will A Mug Last If I Glue Information technology With Milk?

How long the milk technique holds out seems to exist very variable.

Skeptics propose that the organic nature of the casein protein ways it would be very susceptible to estrus and water damage and come autonomously afterward the get-go couple of washes.

I'one thousand sure it depends a lot on the type of ceramic and the severity of the crack, but there are loads of stories online well-nigh dishes and cups that have lasted years of dishwashing after beingness repaired in milk.

My cup has lasted well-nigh 5 washes and so far and is nonetheless going strong. I'll have to update you when the crevice starts to show!

How Can Milk Glue A Mug Back Together?

Milk contains a protein called casein. When milk is heated the casein separates out and settles on nearby porous surfaces, forming a plastic-like material.

When your cracked cup is submerged in the heated milk, the casein settles into the crack and kind of bonds the two rough edges together.

How To Repair A Cracked Mug With Cyanoacrylate Gum

Cyanoacrylate mucilage, aka Crazy glue or Super glue, is clear, quick setting and forms an extremely strong bail with a very sparse layer of glue. Information technology's available in liquid format, which allows it to soak into cracks, and some additives requite information technology meliorate heat and h2o resistance.

All that makes it perfect for repairing a fine fissure in your mug until you lot realize that information technology'south toxic, and hot liquids up against the gum are probable to leach the toxins into your mash.

If your main goal is to make the mug look proficient, fifty-fifty if you can never again drink from it, then cyanoacrylate is probably the all-time way to go.

If you're pretty sure the crack doesn't go all the mode through your mug this might work for you too, but personally, I prefer not to risk getting toxic materials in contact with my food and drink.

• Utilise mucilage advisedly over the fissure line, making sure there is plenty excess to soak in.
• Let information technology soak in for 3-5 seconds
• Quickly wipe off all the excess glue before information technology dries.
• Leave it to cure according to the manufacturer'southward instructions.

How To Repair A Cracked Mug With Epoxy

Epoxy is a 2-part adhesive, consisting of a resin and a hardening amanuensis. One time the two are mixed they begin to cure, forming a very durable bond with whatsoever surfaces they come into contact with.

Epoxy is more than heat and water resistant than milk or cyanoacrylate gum, and unlike cyanoacrylate, it is available in "food-safe" versions. (I'm all the same not convinced most how safe it is for contact with food. Even "food-safe" epoxy contains BPAs which have been linked to all kinds of health conditions.)

The drawback with epoxy is that information technology requires a bigger gap betwixt the two surfaces to exist bonded. And so while it might exist great for gluing whole pieces back on or filling in larger cracks or fries, it'south probably not ideal for a hairline cleft.

The method is the aforementioned as for cyanoacrylate glue, with the additional first step of mixing the resin and the hardener.

Other Ways Of Restoring Croaky Mugs

• Professional restoration: If the mug is invaluable to you and you don't trust your DIY skills, you could accept it to an antique dealer or ceramic studio and pay them to exercise it perfectly.
• Kintsugi: Japanese for "Gold Joinery", Kintsugi is as much a philosophy as information technology is a technique. Using lacquer and gold dust to join upwards cracked surfaces, information technology celebrates the history of an object rather than hiding flaws, often with very pretty results.
• Repurposing: Since it's not virtually the contents and so much as the vessel, the all-time way to preserve your dear mug might be to stop drinking out of it. Use it equally a pencil holder, a institute pot or a candle and so you still go to await at it while sipping your brew out of something else.

Can I Use Milk Or Glue To Set Bigger Cracks? And Breaks?

Although milk has been credited with fixing bodily breaks in ceramic objects I'm not sure how believable those stories are, or how long the repair would concluding.

For larger repairs stick to mucilage of some sort. If yous plan on drinking out of the mug again then go with the "food-safe" epoxy.

If it'due south a wide crack you could try heating it up very gently in the oven kickoff to open information technology up and get the epoxy inside. As it cools the crack will clamp down on the epoxy for a tight bring together.

If the crack extends all the way through, essentially splitting the piece in ii, yous might do best to break the 2 sections apart and mucilage them back together, rather than filling in the crack.

If you're gluing two pieces together, make sure you lot take them firmly taped or clamped in place for as long every bit the gum takes to cure.

The cleft in my mug is stock-still for now but I've taken this as fair warning that I need a new mug to which to adhere myself. Hopefully, your repairs will requite you the time you need to supervene upon yours too!
