My wife was sorting and cleaning some old china she had inherited years ago, among them was this small teacup which had been repaired in a way I had never seen. Small holes had been drilled into the china, then staples inserted, clamping the two broken pieces together. Presumably the broken joint was also glued with some unknown substance, inside the cup there is only the crack.
It's a simplified version of the Japanese technique Kintsugi, the art of putting broken pottery pieces back together with gold - built on the idea that in embracing flaws and imperfections, you can create an even stronger, more beautiful piece of art.
Apparently this method of repair is not uncommon, more on the technique here.
