I heard from a number of people, and on TV that if you strike a spark plug on a glass window (ie. a car window) it will shatter. How does this happen?

Hi Troyboy!
Automobile glass, with the exception of the windshield, is tempered glass. This is often referred to as a type of "safety glass". Tempering is a glass production process that creates glass that is very strong against blunt force. However it will shatter into small non-sharp pieces if fractured by a sharp object. A car's windshield is laminated and will not shatter in the same fashion.
Tempered glass is often used in other applications as well. Computer Monitors, for example, are generally tempered glass.

There is nothing really special about a spark plug that would break the glass other than it has a small area of impact that could fracture the glass. Truthfully, any small tool will do it, particularly if it has a pointed end. They actually make small escape tools you can carry on your key chain or in your glove compartment to break the glass in an emergency...

Spark Plug Ceramic

Mike1942f you dont understand. you can throw a small piece of porcelain at a perfectly good car window, and it will literally shatter. it has something to do with the crystallinity of porcelain. porcelain is made through a process of heating, cooling and reheating ordinary glass, which produces properties of both glass and ceramic materials. it is extremely tough and my suspicion is that the harmonic wavelength of the porcelain (Hrz) vibrates at the right frequency to shatter the glass. anyone else know anything?

You can use that broken shard of a spark plug insulator (the white part) as a glass-cutter.

Yup it does reuire force. But far less force than the brick that failed me. Me and my sister used to sneak into the junk yard and break stuff.
