Shortly following the introduction of the art of glass eye-making to the United States, German goods became unavailable because of World War II. As a result, the US instead made artificial eyes from acrylic plastic. [4] Production of modern ocular prosthetics has expanded from simply using glass into many different types of materials.
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 ...
Batch processing is one of the initial steps of the glass-making process. The batch house simply houses the raw materials in large silos (fed by truck or railcar), and holds anywhere from 1–5 days of material. Some batch systems include material processing such as raw material screening/sieve, drying, or pre-heating (i.e. cullet). Whether ...
The list of raw materials used to formulate a clay body or glaze. Invariably expressed as percentages, and totalling 100%. Also called formulation. Roller-head machine Used for the mass production of pottery: a heated, rotating tool that replaces jigger and jolley to shape wares. Raw A clay, body or article that has not been fired. Raw glazing
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 ).
Selenium, like manganese, can be used in small concentrations to decolorize glass, or in higher concentrations to impart a reddish color, caused by selenium nanoparticles dispersed in glass. It is a very important agent to make pink and red glass. When used together with cadmium sulfide, [9] it yields a brilliant red color known as "Selenium Ruby".

In the 1930s, Saint-Gobain of France first developed foam glass with calcium carbonate as a foaming agent. In 1932, it applied for a patent. [5]An early report of foam glass as a construction material was made by the Soviet scientist, Professor Isaak Ilych Kitaygorodskiy at the All-Union Conference on Standardization and Manufacture of New Construction Materials in Moscow in 1932.
