Tempered safety glass shatters into blunt pebble fragments on impact
Stored thermal surface tension makes broken tempered glass disintegrate safely
Tempered safety glass used in car side windows and shower doors is heat-treated to lock surface layers into compression while keeping the interior in tension. When broken, this stored energy causes the pane to disintegrate into tiny, rounded blunt dice rather than dangerous sharp razor shards.

Tempered safety glass shatters into blunt pebble fragments on impact: the short answers
- Where does this come from, and can I check it?
- Stored thermal surface tension makes broken tempered glass disintegrate safely. The figure is taken from Encyclopaedia Britannica, which is linked in full on this page. Every fact on Mondo Knows names its source rather than repeating an unsourced claim.
- Is this really a everyday life fact?
- Yes. It sits on the Everyday Life shelf, one of 1,090 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.
