Use for decolourizing of Ferric and Ferrus oxide , green colour to colourless. But Selenium have many oxidation state and can change oxidation state when furnace condition change Reduction to Oxidation.
If light goes from flint glass into ethanol and the angle of refraction in the ethanol is 27.6, the angle of incidence in the glass is approximately 23.21. This calculation is based on refractive index of pure flint glass being 1.60 and refractive index of ethanol being 1.361.
In the past, selenium was mainly used in the production of glass to remove color caused by impurities and to make glass more transparent. It was also employed in photographic paper to increase sensitivity to light. Additionally, selenium was used in early electronics as a rectifying agent in devices like rectifiers and photovoltaic cells.
The refractive index of flint glass is 1.6, approx. This means that the speed of light in flint glass is 1/1.6 of its speed in vacuum. This makes it 187,380,000 metres per second.
Metal oxides such as cobalt oxide, selenium, and gold chloride can be used to tint glass. These elements are added to the glass during the manufacturing process to alter its color.
Selenium is a mineral that acts as an antioxidant in the body, which may help protect cells from damage that can lead to cancer. However, more research is needed to determine the role of selenium in cancer prevention and treatment. It is important to talk to a healthcare provider before using selenium supplements for cancer.
selenium is inside many foods ,soil, and glass
By adding gold or copper and selenium compounds to melted glass.
Selenium is represented by the symbol Se on the periodic table. It is a nonmetal element with various industrial uses, including in electronics and glass manufacturing.

If light goes from flint glass into ethanol and the angle of refraction in the ethanol is 27.6, the angle of incidence in the glass is approximately 23.21. This calculation is based on refractive index of pure flint glass being 1.60 and refractive index of ethanol being 1.361.
Several selenium applications:- rubber vulcanizatuin- solar cells- red glass- alloying element in brass- foods supplements
Cullet is actually a variant of word collet. This refers to the ring of glass that was left on the blow pipe when a glass blower was finished with a piece. The glass blower usually broke the leftovers off the pipe with a small hammer. The pieces were called the collets and recycled in the next batch of glass. Nowadays cullet means most any scrap glass. Flint glass usually refers to glass with a high lead content. But lead is not used much in regular glass container production anymore. Most flint glass nowadays is made with Soda and Lime (EAPG). The term flint can be applied to most any hard clean glass for recycling. Plate glass etc. Hope this helps.
The element that is used to make pink glass is selenium. This element is also used to make glass that is red in coloring.

Additionally, selenium was used in early electronics as a rectifying agent in devices like rectifiers and photovoltaic cells.
Flint is a common name for a form of sedimentary rock called chert, formed from microscopic siliceous (essentially quartz) skeletons of radiolarians. As such the hardness of chert is 7, which is slighly harder than glass and considerably harder than steel. If it will scratch glass it is likely to be flint. Flint is often mistaken for limestone or marble, which is much softer and will not scratch glass.
Flint is a type of Quartz, and Quartz is a 7 on the Mohs Hardness Scale
Several selenium applications are:- fabrication of red glass- additive for the electrolysis of manganese- minor additive to fertilizers- copper alloys-vulcanization- solar cellsetc.
