A classic 20-facet Soviet table-glass, produced in the city of Gus-Khrustalny since 1943. Tumblers are flat-bottomed drinking glasses. Collins glass, for a tall mixed drink. [5] Dizzy cocktail glass, a glass with a wide, shallow bowl, comparable to a normal cocktail glass but without the stem; Faceted glass or granyonyi stakan
Laboratory glassware may be made from several types of glass, each with different capabilities and used for different purposes. Borosilicate glass is a type of transparent glass that is composed of boron oxide and silica, its main feature is a low coefficient of thermal expansion making it more resistant to thermal shock than most other glasses ...
A glass building facade. Glass is an amorphous (non-crystalline) solid. Because it is often 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. "glass", "glasses", "magnifying glass".
GLASS-z12 was initially announced as GLASS-z13 because it was thought to have a higher redshift of z = 13.1. [7] [2] This redshift value was later revised down to z = 12.4 in October 2022, resulting in the renaming of this galaxy. [1] GLASS-z12 has a light-travel distance (lookback time) of 13.6 billion years. [5]
Broadly, modern glass container factories are three-part operations: the "batch house", the "hot end", and the "cold end". The batch house handles the raw materials; the hot end handles the manufacture proper—the forehearth, forming machines, and annealing ovens; and the cold end handles the product-inspection and packaging equipment.

Roman glass from the 2nd century Enamelled glass depicting a gladiator, found at Begram, Afghanistan, which was once part of the Greco-Bactrian Kingdom, but was ruled by the Kushan Empire during the contemporaneous Roman Principate period, to which the glass belongs, 52–125 AD (although there is some scholarly debate about the precise dating).
Cut glass wine glass made of lead glass. Lead glass, commonly called crystal, is a variety of glass in which lead replaces the calcium content of a typical potash glass. [1] Lead glass contains typically 18–40% (by mass) lead(II) oxide (PbO), while modern lead crystal, historically also known as flint glass due to the original silica source, contains a minimum of 24% PbO.
