The ratio may be of the type Na O/1.8SiO,, for example. In an ordinary window glass the molar ratios are approximately 1.5 mol Nago, I mol CaO, and 5 mol SiO,. Other glasses vary widely (Table 11.2). Typical manufacturing sequences can be broken down into the following: Make material and energy balance for this process
