The Bologna Bottle: Glass So Fragile It Shatters From Within
Original: Bologna Bottle
The Bologna bottle is a 17th-century glass curiosity made in Bologna, Italy. It looks solid and can withstand blows to its outside, yet shatters into fragments when a small object is dropped inside or its interior is scratched. The effect comes from uneven cooling during manufacture, which leaves internal strains in the glass.
Why now: Readers are sharing this as a surprising example of how manufacturing stresses can make an object tough on the outside but fragile inside.
