Adhesives

A book suggested that for broken object, e.g. porcelain,when the surface of broken pieces are cleaned well and well polished, there is no need to use any adhesives to stick the broken pieces together. Is it possible?

I will answer using my brain only (so don't take this as a reference like could be a well known book). The answer is "no" but in some very rare cases it could be a yes.
I explain : If you break an object into exactly 2 smaller objects and that the part where they were encrusted into each other is polished very well, then it is possible to assemble each other to form a single object, almost the same as the first object (almost because when you polish an object, you lose atoms or molecules, depending of the material). Now if you are lucky, you broke the first object in such a way that when you assemble the 2 parts it can need no glue to maintain itself as a single object. If you are not lucky (and this will happen in most of the cases due to probabilities, my instinct tells me it), you won't be able to maintain the 2 parts as a single object. For example if you broke the head of a statue following a parallel plan with respect to the ground, then after polishing the 2 pieces, the head will be able to remain over the body without the need of glue. (but of course it will be very fragile and will be separated if someone forces on the head). But if you broke a hand, then no matter how you will polish the 2 parts, it is very probable that it won't stay on the statue but will fall of onto the floor.
If you didn't understand me at all or a part of what I said, just ask me. (my mother tongue is not English).
