Webglass, an inorganic solid material that is usually transparent or translucent as well as hard, brittle, and impervious to the natural elements. Glass has been made into practical and decorative objects since ancient times, and it is still very important in applications as disparate as building construction, housewares, and telecommunications. 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. grantcraft from words to actionWebCrown glasses, flint glass, and borosilicate glasses are often used in optical instruments. Crown glasses have a relatively low Abbe number (50-60) and are used in making achromatic lenses. Flint glass is a harder type of glass with a higher refractive index than crown glass.
