Iron oxide, also known as iron oxide red, is a commonly used color pigment in glass production. Glass colored with iron oxide absorbs both ultraviolet and infrared radiation. Different iron oxide contents during glass production result in different colored glasses. Therefore, it is widely used in the manufacture of heat-absorbing glass and colored glass, such as bronze, blue, green, and gray glass.
Iron oxide is inexpensive and provides the property of absorbing heat and ultraviolet radiation, making it an important chemical material in glass production.
