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?

•@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.

@Gabor Heja @Granny Art (Shrimp)vis.soc mod @Surly Amy 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.

•Is Tech-Bond "food safe"?

@Dan Lyke 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!

•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.

@Dan Lyke Damnit - I'm an idiot - just checked the silicon *literally sitting on my desk right now*
It's safe to eat out of and heats to 400 degrees F

•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.

•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!
