  1. For me, I view it as not safe to keep using a cracked coffee mug. I think a cracked mug can have further cracks or be damaged more with use. I figure a “cup is a cup” and it can easily be replaced while leaving out being sentimental, nostalgic or the emotions of a long-used coffee mug that one may have grown to love or be fond of using. Move on with a newer mug. There are so many to choose from.

  2. Maybe. Maybe not.
    In the any-crack-is-dangerous camp: Even if it’s just a crack in the enamel coating you chuck it out. The better solution is based on whether you have a dishwasher that gets to bacteria-killing temperatures? If you drip dry your dishes, a cracked cup can be breeding grounds for all kinds of little nasties. A cold water dip in a chlorine bleach solution also works.
    If it’s a crack that goes through the cup, that you can see on both the external and internal surface it’s going to break when you least suspect it, so throw it out.
    My most serious Duuuuh Moment with a cracked cup…. I had a favorite mug. The crack was on the glaze around the seam where the handle was attached to the mug. I listened to that crack scrape a bit every time I lifted the cup. I figured it would come off one day while I was washing it and I’d finally have to give up the ghost on my comfy favorite mug. I remember actually thinking that I might just sand down the rough spots where it finally snapped off and use my mug Asian style, handle-less. What I didn’t suspect was that the handle would come off just as I lifted a twelve ounce hot latte! Right on my laptop keyboard. Lesson learned. Luckily that was back in my business years and the company IT guys could get it replaced under the sweetheart agreement we had with our supplier (we bought a helluva lot of PCs and laptops).

  3. For my personal, at home use, I have used a cracked cup for years—decades even. For me, it is like that old torn, and stained flannel shirt I have worn off and on for twenty or more years. That shirt will not see the inside of a trash bin until after my passing. That cracked cup will continue to be a temporary holding unit for my morning coffee—at least until is starts to leak. After that, I may have it enshrined.
    However, for public use, I think it generally unsafe and unsanitary to drink from a cup which has chips or cracks. This thought is shared by most Public Health Agencies and restaurants will get dinged for using diningware having chips and cracks.

  4. No. Typically the clay and paint used contain high levels of naturally occurring mercury, lead, and other toxins that are harmful to humans and will slowly leach into your body. Google the effects of these on the human body and then throw out that mug, or keep it around and use it as a pencil holder or other function instead of using it to drink from.
    Besides, you can buy some amazing mugs for as little as $1 at many retail stores, so why risk your life and health.
    What you can use them for is other purposes like holding t…

  5. If you absolutely have to have coffee or you’re gonna die without it and there is nothing else available, then yes.
    Just be sure to wash the cup with soap and water after every cup of coffee.
    God Bless You.

  7. Probably. I am sure millions of people do at work. I wouldn’t drink from it if the liquid has been left to get cooler for a while though: any bugs in the crack will have time to multiply.

  8. yeah. until that one morning when the whole thing breaks apart just after you’ve filled it with boiling hot water. you know, new coffee mugs only cost around a dollar. you can buy them at the cheap shops. so really. maybe it’s time to splurge on a new one.

  9. I have done it for years just every now and then put straight Clorox in the cup and let it stand overnight then you won’t have any problems with bad coffee and or maybe get sick from the microscopic growth that made might have grown in the crack

  10. Sorry but no. Those cracks will eventually crack apart. There’s no knowing when it will happen. It could be this week or 3 years from now.
    The heat can accelerate the process as well as putting it in the microwave.
    Bacteria can hide in those little cracks.

  11. I would not use it. The purpose of the mug for food or drink is to be intact. Believe in the quality of your life and get a non-cracked mug. Use the cracked one for a nice houseplant 🌵

  12. Yes although it may harbor harmful bacteria but the bacteria risk is so minimal as to be ignored, assuming that the cup is appropriately washed before use.
    However, I dispose of cracked/chipped cups because of the risk of spontaneous cracking/chipping allowing pottery shards into my body.

    It is a violation of the health code for restaurants to do this. Does that give you an idea as to why this is a bad idea to keep using it?

  15. Not really.
    Depends where the crack is I guess.
    If the handle is cracked, broken or missing, you have a handle-less mug. That will still hold liquids just fine, but be careful with sharp edges or loose parts.
    If the mug itself is cracked somewhere on the body, you will have leaks or spills, so it’s not as useful now. Better off repurposing it if the crack is not too bad, like a small planter or pen holder.
    If it’s bad enough that it can’t be repurposed, then toss it.

  16. No it is not safe to use cracked coffee mug.
    Although not proven to be dangerous
    in finished form, a crack , chip or scratch along the inside or the lip portion of a plastic mug can emit trace amounts of plastic substances, such as bisphenol A, or even flake off fragments into the liquid, making the mug unsafe to use.

  17. Bacteria can live in the cracks , but I’ve never know anyone to get a bacterial infection from using a cracked cup . I throw them away because I don’t need bacteria in my bladder (UTIs when I was younger…antibiotics w/o probiotics) anyway, coffee is antibacterial (at least black coffee is ), so if it’s coffee your drinking, I think you’re probably ok.

    Reply
  18. Not really; bacteria will build up in the crack, & the cup will get weaker until one day you go to pick it up & it breaks & you’re wearing hot coffee.

  19. No, in this age of abundance don’t be cheap. Buy a new one, you may like it better.
    If the mug was a gift, put it on a shelf. If you’re asked why you’re not using it, explain it was just too beautiful and you were afraid you might break it.

  20. If the coffee mug is cracked and you keep using it. Surprise. One day with the mug filled it will crack open and the liquid will be all over you. Hope it won’t be something so hot as to burn you. Buy another mug.

  21. “Is it safe to keep using a cracked coffee mug?”
    If the coffee mug is cracked, being what it is, (and if people haven’t noticed the crack, or the crack is barely visible; perhaps the crack is on the side right-handed people never see, due to it being on the opposite side of the mug when they pick the mug up by the handle,) the mug will be filled with boiling hot water/beverages, this could cause the cracked coffee mug to give way at any unexpected moment. That being the case, it is not “safe” to keep using the cracked coffee mug as though it’s integrity were sound, when clearly it is not.
    A new coffee mug will set you back but a mere trifle, even a new matching set of sound coffee mugs is not exorbitantly expensive so as to warrant the continued unsafe use of a cracked coffee mug. Not only could the cracked receptacle give way at any moment, with likely piping hot contents scalding the unsuspecting recipient, even if the mug holds together, there may be other undesirable elements being leeched from the mug’s crack and into the person’s beverage!
    Never mind that it is unsafe, it displays a lack of regard and respect to offer someone such a mug. Discard the object, or use it for a pot plant/something that is never going to see it being used as a coffee mug again. I have seen sticker kits for making a 3D goldfish with resin, if it’s hard to part with a particular keepsake, you can look them up easily enough on you tube, people use little bowls/pots, layer them with resin, then a sticker/decal, then a little more resin until they have completed the stages and these can look quite effective, that way you don’t have to lose your precious, or novelty mug, or run the risk of having it lose it’s scalding contents into a loved one’s crotch!
    Have Fun,
    Carlos.

  22. Depending on how cracked it is, I don’t see why not. People have been drinking out of cracked crockery for centuries. As long as it’s not leaking, it shouldn’t be of any consequence. Some may say germs can get in the cracks, but I say again, people have been drinking from cracked crockery for centuries. Before mass production was practical, people had to use what they had as long as possible.

  23. Cracked coffee mugs are not safe to used as coffee normally are very hot which while holding the mug may break anytime thereby spilling the hot coffee on your lap… Which may possibly be scalding hot!

  24. I spend 26 pence a day on the gas bill. I hate spending money, but if I have a cracked mug I throw it away and replace it straight away. Germs get in the cracks and multiply.

  25. Depends how cracked, it is. If it’s been glued, and cleaned, it’s safe to use. IF it’s liable to fall apart, no. You should dispose of it.

  26. It depends on the crack.
    If the crack is only on the surface and not through the entire wall of the cup, I call it a patina and keep using the mug. (Language is a lovely thing.)
    If the crack is through the entire wall of the mug, I would recommend stop using it before your left holding half a mug with the rest of it, and the coffee that was inside, now in your lap.

  27. Use your common sense. If it’s a small crack, you’ll probably live. If half of the mug is missing, it probably won’t hold any coffee, but in case you’re an American, coffee burns just might give you an opportunity to sue somebody.

  28. If it has sentimental value keep it but don’t drink from it. If it is ceramic you could end up ingesting some sharp fine pieces of the mug, or it might break apart. But it is no longer a good idea to use it. But we probably have some mugs that have very small cracks that we still use. I would not use it if you question if it is safe.

  29. Cracked ceramic is unsafe; it could cause leakage that could lead to mold, permanently ruining your mug. A sudden jar or clink also may turn the crack into a shattered mug. You can fix a cracked mug if you catch it early. Gentle hands and the right glue can turn that cracked mug into a working ceramic keepsake.Although not proven to be dangerous in finished form, a crack, chip or scratch along the insid…

  30. You can repurpose it into an art piece if it has emotional meaning. It may be the safest and most fun approach. Patch up the crack with something artful and attractive to your visual taste. Afterwards, or perhaps shortly before you start this art project, replace the coffee cup with a new one you’ll use for coffee and other drinks. You’ll have less worries.

  31. No, you should probably get rid of the mug. The crack can fail, covering you in hot coffee and/or the crack can harbor microbes which can make you sick.
    Neither of which are good.

  34. “Safe”, from the perspective of it structurally failing and dumping hot coffee on your nether regions? – No.
    “Safe”, from the perspective of transmitting some dreaded infection from the last person who used the mug? – Yes. That hot coffee has already eliminated any bacteria that may have escaped the washing process. This is another one if those imaginary threats (like the hair in the soup), that appeals to our sensibilities, but has never been recorded as causing anything bad.

  35. Probably not. As you continue to use it, the crack will get more and more pressure put on it, either from your hands, or being washed, or just general use (setting it on table, in cabinet, etc). Eventually the crack will give way, it’s just a matter of when. I personally would not want to end up with a lap of hot coffee or tea. You could still potentially use it as storage, perhaps to hold toothbrushes or pencils or something similar. It would likely last much longer that way

  36. It is not safe or advisable to continue to use a cracked coffee mug. Heated or hot liquid causes materials to expand, expansion and contraction weakens materials. Eventually that crack will grow and possibly break. If it has a crack in it then replace it.

  37. giulio moro has it right. your main concern with a cracked mug is about the pigments involved. lead is still in common use. your mug is fine, until the glaze is cracked. at that point, unless you want to do some intensive research to find out from the manufacturer regarding the clay and pigments used in your mug, it’s not worth it. even a hand-thrown pottery mug from an artisan may not be dated and marked sufficiently to determine the specific supplier of that batches’ clay and pigments. this is a major reason why even artisans like to glaze their ceramics. the right glazing can make most ceramics food safe, very inexpensively. this is such common usage, many potters can focus on the visual appeal, knowing their mugs and bowls are safe, as long as the glaze is intact.
    as far as concerns over bacteria, many dishwashers have a sanitizing feature, which we should all be using at this time, to further protect against covid-19. i would be far less concerned about bacteria surviving in a cracked cup.

    throw away after final use…

  41. Not so much. Once there is a crack in a dish, you may never get it completely clean again. Growing up, we used cracked tableware fairly often, but it really isn’t worth the health risk.
    The other issue is that adding hot liquids or foods to cracked containers or plates may trigger a total break. Do you really want to take the chance of scalding hot liquid being dumped into a lap? Cups can be had for very little. How much would an er visit and follow up cost?

    Reply
  42. No. Bacteria enters the crack and can not be removed with ordinary cleaning. It is best to either toss the mug or use it as a planter if it is something you want to keep.

  43. I would not use a cracked mug. THere’s too much chance it will break, and if it does, you could have a mess to clean up, or worse, you could get hurt.
