Abstract It is demonstrated that transformations of iron oxides in glass melting occur mainly in the solid phase. The ratio between the two forms of iron oxides in a glass melt is determined by the melt temperature. Achieving an equilibrium with the gaseous medium requires a long time due to high melt viscosity and low diffusion coefficients. To ensure high service parameters in products, one needs stability of raw material compositions and melting process parameters, including diathermancy of the melt.

glass is not made light sensitive it is born light sensitive
if you have a small nose,can i ask you why do you have small eye. it is like that
glass is sensitive since it is its property (i.e)transparent property
or reflecting property when it is coated at one side
some glasses are opaque since due to their density and thickness because that property depends upon thickness and density

it's not the glass itself its a thin piece of material that is embedded within the glass that reflects the light away to make it darker and like wise reflects it to make windows let in more light

the phenomenon is called photochromism:
