Unbreakable Glass
Unbreakable glass is glass, or glass substitute, which does not display the normal fragility of glass – in general the term is not used to refer to something that is absolutely unbreakable.

Tiberius asked if anyone else is aware of the invention. When the inventor replied that he was the only person who knew the secret, Tiberius had him killed, in order to protect the livelihood of the glassmakers.

Glass is an amorphous (non-crystalline solid, non-crystalline) solid. Because it is often transparency and translucency, transparent and chemically inert, glass has found widespread practical, technological, and decorative use in window panes, tableware, and optics. Some common objects made of glass are named after the material, e.g., a Tumbler (glass), "glass" for drinking, "glasses" for vision correction, and a "magnifying glass". Glass is most often formed by rapid cooling (quenching) of the Melting, molten form. Some glasses such as volcanic glass are naturally occurring, and obsidian has been used to make arrowheads and knives since the Stone Age. Archaeological evidence suggests glassmaking dates back to at least 3600 BC in Mesopotamia, Ancient Egypt, Egypt, or Syria. The earliest known glass objects were beads, perhaps created accidentally during metalworking or the production of faience, which is a form of pottery using lead glazes.
