Container glass is a type of glass for the production of glass containers, such as bottles, jars, drinkware, and bowls. Container glass stands in contrast to flat glass (used for windows , glass doors, transparent walls, windshields ) and glass fiber (used for thermal insulation , in fiberglass composites, and optical communication ).
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.
Recycling codes on products. Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process.The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.
Cobalt glass—known as "smalt" when ground as a pigment—is a deep blue coloured glass prepared by including a cobalt compound, typically cobalt oxide or cobalt carbonate, in a glass melt. Cobalt is a very intense colouring agent and very little is required to show a noticeable amount of colour. Cobalt glass plates are used as an optical ...
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
Gold-band glass is a related Hellenistic and Roman technique, where strips of gold leaf, sandwiched between colourless glass, are used as part of the marbling effect in onyx glass. It is mostly found in small perfume bottles and the like.
The bond strength is also governed by the character of the oxide layer on its surface. A presence of cobalt in the glass leads to a chemical reaction between the metallic iron and cobalt oxide, yielding iron oxide dissolved in glass and cobalt alloying with the iron and forming dendrites, growing into the glass and improving the bond strength.

More recent excavations of contemporary settlements have revealed fragments of similar vessels types, indicating there are few, if any, differences between domestic glass and those ritually deposited in graves. [5] There is a significant difference between Roman and Anglo-Saxon vessel forms, and glass working techniques became more limited.
