Spontaneous glass breakage is a phenomenon by which toughened glass (or tempered) may spontaneously break without any apparent reason. The most common causes are:
-
- Minor damage during installation such as nicked or chipped edges which later develop into larger breaks
- Binding of the glass in the frame causing stresses to develop as the glass expands and contracts due to thermal changes or deflects due to wind
- Internal defects within the glass such as nickel sulfide inclusion.
- Thermal stresses in the glass
- Inadequate glass thickness to resist wind load

Famous quotes containing the words spontaneous and/or glass:
“My vocabulary dwells deep in my mind and needs paper to wriggle out into the physical zone. Spontaneous eloquence seems to me a miracle. I have rewritten—often several times—every word I have ever published. My pencils outlast their erasers.”
—Vladimir Nabokov (1899–1977)
“When God at first made man,
Having a glass of blessings standing by,
“Let us,” said He, “pour on him all we can:
Let the world’s riches, which dispersed lie,
Contract into a span.””
—George Herbert (1593–1633)
