Why are beveled edges vulnerable?
These areas are vulnerable because there is little material available to resist the full impact of a pot, pan or other heavy object. A beveled edge signifigantly reduces chipping. Edges that are well rounded or beveled help deflect the blow, changing the type of impact force from a shearing force to a compression force.

The only ingredient that's not rock is water. You need the water to ignite the chemical reaction that transforms the powdered Portland cement back into solid rock again.
