I have an opportunity to purchase 9 Luxfer tiles from a Frank Lloyd Wright building that was demolished. These tiles are in good condition, slightly chipped, no cracks, color is clear not lavender yet, as they were from a protected porch area. Does anyone know particulars that I should be aware of BEFORE my purchase? Also, do you have suggestions as to the best way to mount these? I have seen a piece done with lead such as a stained glass/lead window. They are only 1/4"? thick, so seem to be more fragile than glass block and since they're over 100 yrs old, I would presume protecting them from the elements would be wise. Also, should I keep them from sunlight or allow them to turn lavender in sunlight (sounds pretty to me).
