7 Years of Bad Luck for Breaking a Mirror
It is said that seven years' bad luck will result from breaking a mirror.
No. After breaking the mirror, the chemical properties of the remaining pieces are the same as the intact mirror. This is a physical change, not a chemical change.
Breaking a mirror does not cause a change in the chemical properties of the mirror itself. The act of breaking the mirror may result in physical changes, such as the mirror's fragments having sharp edges, but the chemical composition of the mirror remains the same. Mirrors are typically made of a layer of reflective material, like silver or aluminum, which is deposited on the glass surface, and breaking the mirror does not alter this composition.
