• The main components of borosilicate glass, popularly known as "hard Glass," are silica and boron oxide. Borosilicate glass has a thermal expansion coefficient of about one-third that of ordinary glass.
• Lenses and prisms are made from flint glass, which is a highly refractive lead-containing glass.
• A glass bottle is one that is constructed entirely of glass. Glass bottles come in a wide range of sizes, although the most frequent sizes are between 200 milliliters and 1.5 liters.
