MUTE BUTTON FOR THE WIN!!
is it a crack crack? Or did a piece of the vase break off? I would try Gorilla Glue, that stuff is amazing. When I played baseball, I broke my favorite bat, so i glued it with that crap and put a nail in it and it was like brand new. FYI, when the glue dries, it dries white, it won't be clear.
