"hmmmm....well it's been quite some time since I last researched glues and adhesives so I'll give you what I remember off the top of my head though newer information could be out there. I may not be remembering exactly correctly anyway. Generally speaking it was hard to find a "good" glue.

Crazy glue and similar types as I recall can cause some ceramic bodies to degrade over time. The contact type of glues often used in museums paraloid/acryloid are reversible but I find them a bit difficult to make "look" good. The low yellowing two part epoxy Hxtyl nyl is expensive and hard to reverse. So what to use????? Before paraloid the old advice was a PVA (simple white glue) as it could be reversed with water if yellowed or weak however I think it's fallen out of favor and may not be as reversible as once thought. (Apparently Elmer's glue used to be a simple PVA but I've read they changed the formula awhile back so there were preferred other brands.) Anyway I don't repair much anymore but for my own I use a simple white PVA glue (not Elmer's) or Hxtal nyl though I have used paraloid/acryloid."
