Why It Happens
An oven door can shatter without impact due to long-term stress rather than misuse.
Heat, materials, and everyday habits slowly weaken the glass over time.
Glass and Heat Stress
Oven doors are made from tempered or borosilicate glass, designed for high temperatures but not indestructible.
Repeated heating and cooling cause expansion and contraction, creating internal stress.
Extreme heat, such as during self-cleaning cycles, increases the risk.
Hidden Flaws
Manufacturing imperfections, including microscopic nickel sulfide inclusions, can expand gradually with heat.
These invisible flaws may trigger sudden shattering long after installation.
Reducing Risk
Slamming the door, leaning on it, scratching the glass, or exposing it to sudden cooling can worsen damage.
Gentle handling, careful cleaning, avoiding rapid temperature changes, and watching for cracks can help prevent rare but alarming failures.
