   I broke a coffee mug over the weekend, it was new, I wanna fix it.

   Looks like stake of the art is Epoxy and most epoxy isn't food safe?

   Art Resin brand Resin is FDA certified food safe (they say FDA certified and in Canada and Great Britain and 13 other countries, which is a claim you can't make without getting in very fraud, but also worthless), but it only allows up to 50°C before that's worthless.

   The MSDS on other resins and epoxies seems to be not food-safe?

   Anyone know how to fix a coffee cup?

   Was thinking maybe finding some non-PB tin?

     Fun fact - there are a billion articles on how to do this - all made by an LLM who doesn't know what food safe is and is just recommending random glues

     @artcollisions @SurlyAmy Gotta use the right epoxy - needs to be similarly strong. I am repairing the side, not the handle, which holds weight.

     @silverwizard @SurlyAmy is it possible to fix a ceramic mug? I had one that the handle broke off (several times). My husband glued it on until it gave up the ghost and crashed to the floor one day and cracked the body of the mug as well.

     @troublewithwords Yeah, raw melted tin with a silicone heat resistant brush and melted tin is *probably* enough - but uh - yeah - not super duper safe.

     @silverwizard I see a few people have suggested kintsugi. Despite the name it can be done with tin, though a quick didn't reveal any MDS for any of the tin preparations intended for it. 😏

     @resuna The problem is that for those kits I'd want to see their heat data and food safety data, since a lot of the examples are cold examples.

     @silverwizard @artcollisions @SurlyAmy I was about to jokingly suggest that you could drill, tap and use screws/bolts, but then my Google search resulted in ceramic bolts and now I want one. Or a bag of them. They look too nice but even more fragile.

     If I had to repair a mug I'd either use the 50 °C resistant epoxy and hand wash it afterwards or (if it'd be the handle) use any temperature resistant glue anyways.

     @gheja @artcollisions @SurlyAmy The probably is less the washing and more the making coffee directly in it with 100°C water.

     Those bolts look really cool - I wonder what primary use for them is.

     @danlyke Yeah - that says safe if not in direct contact with food - which I don't think works since it's a large broken chip. But yeah! This is it! An hour of LLM spam to find something and then read data and not quite right.

     The wikipedia page definitely supports the reading that it's probably not good for eating off of.

     Also! Thanks so much for digging for me!

     @silverwizard Cyanoacrylate? It's hard to wade through the AI generated link spam on Google for info on food safety (this one claims Krazy Glue is, Krazy Glue's site is less positive https://tbbonding.com/is-tech-bond-food-safe/ ), but I know there are wound contact formulations...

     @silverwizard This was a cheeky guess. A more general guess would be strong electromagnetic field applications where metal screws could interfere with the fields.

     @silverwizard Yeah, for personal use I'm cavalier enough that wound safe sounds good enough to me, the standards for food safe are amazingly high, but I'm also getting to the "at some point the long term risk factors become less concerning" age...

     Are the platinum cure silicones clear? Because that might work for a chip.

     @JoshuaACNewman What do you mean food safe when cured? Is there a test for this? I am a little bit cautious about this kind of thing - it seems to be the case for Art Resin but not all resins? But the problem there is debonding at high temp?

     @silverwizard Epoxy is food safe when cured. Mix it completely and give it a day to cure.

     Superglue (cyanoacrylate) also works fantastically on ceramic even though it was developed for medicine.

     @silverwizard Cured epoxy is nonreactive. It’s used to make artificial body parts. If you’re worried about leftover, uncurred resin or hardener, they both dissolve in acetone so you could wash it afterward.

     However, if the fit is still good, superglue will be easier. And that stuff cures quick and completely!

     @silverwizard Yeah, I see that. So, if Art Resin is certified, why wouldn’t you use that? (Or cyanoacrylate, which is cheaper, very fast-curing, very strong, and originally for medical purposes?)

     @silverwizard @gheja @artcollisions ceramics are often used on the surface of spacecraft and other high temp objects because they can withstand higher temperatures than metals that melt so I’m going to assume it’s for that instead of firearms and pretend society isn’t garbage. Hahaha

     @silverwizard @artcollisions TBH, I don’t know of any truly safe way to repair ceramic mugs that makes them useful again. Only ways that makes them decorative.
