It appears that someone ask a similar question a few years ago and here was the answer https://ask.extension.org/questions/116219. I can't find anything newer. There are some food grade glues - but they appear to be available on a commercial level. The best answer might be to glue it and then use the mug as a decorative piece instead of drinking from it, as i'm sure it has sentimental value to you.
