The properties of glass are modified by which approach?

Question

Quizplus · Accepted Answer

Adding various metal oxides can modify the properties of glass. Metal oxides like lead oxide, boron oxide, and titanium oxide can increase the refractive index, density, and hardness of the glass. Sodium oxide and potassium oxide can reduce the melting point of glass and make it more workable. Firing at higher temperatures, glazing at low temperatures, and substituting carbon dioxide for silicon dioxide do not modify the properties of glass in the same way as adding metal oxides.
