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 ).
Frit. A frit is a ceramic composition that has been fused, quenched, and granulated.Frits form an important part of the batches used in compounding enamels and ceramic glazes; the purpose of this pre-fusion is to render any soluble and/or toxic components insoluble by causing them to combine with silica and other added oxides.

For the most common types of glass production sulfate raw materials are used, in particular, Na 2 SO 4, decomposing into SO 2 and O 2. Glass types that melt at comparatively high temperature, such as borosilicate glasses , use chlorides , such as NaCl , having a sufficiently high vapour pressure at refining temperatures.

The refractive, reflective and transmission properties of glass make glass suitable for manufacturing optical lenses, prisms, and optoelectronics materials. Extruded glass fibres have applications as optical fibres in communications networks, thermal insulating material when matted as glass wool to trap air, or in glass-fibre reinforced plastic ...
By mid–century, Pittsburgh was the nation's new glassmaking center, and it had as many as 33 glass works by 1857. Nine of those factories made flint glass (crystal). The remaining factories made products such as bottles and window glass. [62] [Note 4] The best known Pittsburgh glass company was Bakewell, Pears and Company. The company was ...
Recently, it is available in monolithic dimensions of 2.8 x 1.2m. [citation needed] Lava foam glass: natural lava such as obsidian and industrial waste slag is used as the base material, and a certain amount of glass powder can also be added to reduce the foaming temperature and foam glass made of or the like as a foaming agent. Generally used ...
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.
