Anotations

Scope note:

Refers to a type of modern cast glass that is made by pouring molten glass into molds, creating a thick glass that may have a chipped or faceted surface. It is used primarily in construction, for example, to create floors or windows set in concrete, sometimes resembling stained glass. It was invented in France around 1900 as a form of paving.
