    Amorphous solid - Properties of oxide glasses | Britannica

    Amorphous solid - Amorphous solid - Properties of oxide glasses: The wide range of the properties of glasses depends on their composition, and special effects result from the presence of various modifying agents in certain basic glass-forming materials (see above Atomic-scale structure). One of the most important glass formers is silica (SiO2).

    Crown glass (optics) - Wikipedia

    Crown glass is a type of optical glass used in lenses and other optical components. It has relatively low refractive index (≈1.52) and low dispersion (with Abbe numbers around 60). Crown glass is produced from alkali-lime silicates containing approximately 10% potassium oxide and is one of the earliest low dispersion glasses.
