Each type of glass has a different structure and therefore a different IOR value assigned to it.
The index of refraction for glass ranges from as low as 1.44 to as high as 1.95, as glass is created in various ways to be used with different applications such as windows, glass bottles, and safety glass. A common question is finding the specific IOR value with a material like glass.
These properties can include diffusing, refraction, and subsurface scattering depending on the material. Materials have a variety of properties to influence how the material is going to respond when hit by a source of light.
