A broken wine glass warning that contents are breakable.
Also known as: Broken glass symbol
A wine glass drawn with a crack or a broken bowl marks a package as breakable. The glass is a stand-in for fragility generally rather than a claim about what is inside.
In the ISO 780 handling series, a glass pictogram indicates that the contents of the package are fragile and it should be handled with care.
Contexts: Packaging
The wine glass stands for fragility in general and says nothing about the contents; a box of glassware and a box of electronics carry the same mark.
Contexts: Packaging
A stemmed drinking glass seen from the side: a curved bowl on a thin vertical stem above a flat circular foot, the bowl broken by a jagged diagonal line with a piece falling away.
Both are used in packaging contexts.
