When neodymium oxide is added into sodium calcium glass and lead glass, the color of glass depends on the thickness of glass and the content of neodymium as well as the intensity of light source. The thin glass is light pink, and the thick glass is blue purple. This phenomenon is called the dichroism of neodymium. Praseodymium oxide produces a green color similar to chromium; erbium oxide is pink when used in photochromic glass and crystal glass; cerium oxide and oxygen dioxide are used The results show that the glass is yellow when titanium oxide is used together; praseodymium oxide and neodymium oxide can be used in Praseodymium Neodymium black glass
