Tiny shards of spark plug porcelain have small hard points which allow them to easily find a breaking point in glass. They can also be used to break the side window of vehicles.
Why does porcelain shatter glass so easily?
Why does this work? The ceramic used in spark plugs is extremely hard compared to your typical “rock”. In addition, the corners are very sharp. This concentrates the force of the hit to a small enough area on the glass that it can scratch and fracture it.
Can porcelain break tempered glass?
Now, take your small piece of sharp porcelain and throw it at the center of the side car window as hard as you can. Even though you are not generating much force with your throw, the sharp porcelain point focuses the force. It should cause a tiny fracture in the tempered auto glass, which will instantly spread out.

Why do broken spark plugs break glass?
When thrown with moderate speed at a side window, a sharp shard of the exceptionally hard aluminium oxide ceramic used in spark plugs focuses the impact energy into a small enough area without blunting to initiate cracking, releasing the internal energy and shattering the glass.
Can you break car window with fist?

Why does a glass ball break in a cone shape?
However, this view is not now generally held and it is widely accepted that cone cracking is due to the surface radial tensile stress at the circle of contact between the sphere and the target, generated by the impact.
Which is stronger glass or ceramic?
In theory, ceramic is stronger than glass. Most modern ceramics have a crystalline molecular structure. Typically ceramic is stronger than glass of the same thickness, and more resistance to heat and thermal changes.
What does porcelain do to Windows?
The result is that the hard, sharp shard of ceramic creates a small scratch in the glass which then rapidly propagates across the entire piece of glass as the internal tension is released. [citation needed] The glass subsequently shatters into many small pieces.”
How much force does it take to break a house window?
Through the annealing process of hardening tempered glass, the force required to break the window is much more than breaking a normal pane. Depending on the manufacturer, the force required to break tempered glass ranges from 20,000 to 24,000 PSI (or pounds per square inch).

Can a spark plug break bullet proof glass?
A: Yes, a spark plug thrown at a car window will break it. So will a rock, a good-size ball bearing or a ball-peen hammer. The side widows are made of tempered glass that, while strong, can be broken with a strong blow. The glass will then shatter into cubes instead of shards so you are less likely to be seriously cut.
