Question

How is the basic recipe for glass modified to make glasses with special properties?

1) Metal oxides are substituted for lime.
2) Nonmetal oxides are substituted for lime.
3) Nonmetal oxides are substituted for soda.
4) Nonmetal oxides are substituted for silica.
5) Metal oxides are substituted for soda.
6) Metal oxides are substituted for silica.

Answer 1

The basic recipe for glass can be modified by substituting different oxide additives to create glasses with special properties.

Step-by-step explanation:

In order to make glasses with special properties, the basic recipe for glass can be modified by substituting different oxide additives for certain ingredients. Metal oxides and nonmetal oxides can be used as substitutes for soda, lime, and silica.

For example, metal oxides like copper(II) oxide, manganese dioxide, cadmium sulfide, cobalt oxide, and nonmetal oxides like iron(II) oxide and chromium(III) oxide can be added to glass to create different colors and properties.
