While finding your mirror cracked can be spooky, there are actually many logical and common reasons why this happens. First, the mirror may have been mounted unevenly in the first place. Over time, poor mounting leads to stress points that will eventually cause a mirror to crack. Other common causes of a mirror spontaneously cracking include dramatic temperature shifts, strong thunder or a loud crash somewhere in the distance, exposure to heat and sunlight, and an uneven wall in your home. It's also possible that your mirror had a manufacturing defect or microscopic cracks that occurred during glass cutting or handling that eventually caused it to shatter.

Bathroom mirrors weigh between 6 and 13 pounds, depending on the size. A 16x20-inch mirror weighs 6 pounds, while a 24x36-inch bathroom mirror weighs 12.5 pounds. Large mirrors, such as a 30x40-inch mirror, weigh 46 pounds. When installing or hanging a bathroom mirror, have a neighbor or partner assist you in lifting and holding the mirror in place. A second set of eyes can also help ensure the mirror is centered and level. 

You don’t want to put anything on top of your mirror when you move it. You also want to limit the possibility that something heavy will fall on the glass and shatter it. For this reason, it’s not a good idea to lay a mirror flat in the moving truck.

To tell if a window is single or double-pane, focus on the edge. Double-pane windows have two glass layers separated by a spacer, which you can usually see around the edges. For single-pane windows, it’s just one sheet of glass. Another easy trick: shine a light at the window—single-pane glass reflects once, while double-pane glass reflects twice. Lastly, if you feel both sides of the glass on a cold day, double-paned windows will feel warmer because of the insulating gap between the panes.
