  You can definitely glue it back. It just won’t ever be permanent. Those stairs are made to break.

    I’ll give that a try. Why do you mean that they are meant to break? They have lasted for 60 years now, that’s not too bad.

      Those stairs have a bullnose that juts out and the whole thing is made from mortar. Mortar is very strong in compression but weak in tension. So a load on the tip of the stairs will put a large tension load on the top of that bullnose where it meets the stair corner. At some point it will break off.

        Makes sense.
