yes the glass was made with a phosphorus compound that is heated all day so at night it is still glowing, in the winter it is not as light like I said the bldg is so different, Tiffany was a very smart man who made this glass to be one of a kind ! Great stuff huh ? No light is needed at night. Cheers.
The Chapel was designed by Tiffany, everything was done for a reason, If you were to look at this window at 3am without any lights it will still glow like this, This window never saw the sun. More to come on this great Chapel.
