Factory glass
Factory glass is a term used by collectors of glass objects with artistic aims to distinguish items, mostly of decorative rather than utilitarian function, made on a larger scale in a factory, from the more individual or unique studio glass and by studio glass artists to distinguish their work from the more standardised items which are generally made in larger glassworks. It can be an equivalent for the 20th century of the term art glass, which is largely applied to 19th-century or early 20th-century pieces.
