Luxfer Prism glass tile. Very pretty. An American thing that started in 1897.

Not your standard old glass brick which came in in the 1940s though if you aren’t looking closely walking through your old business district these will look like a grungy glass brick transom up over the display windows of old shops. But it is not glass brick but rather is from 50 years before. These are square glass tiles that have horizontal prisms on the back, which redirected sunlight from windows where it was plentiful back deep into rooms where light was scarce, reducing the need for artificial lighting and light wells. You could daylight the basement below, too, where the stock was kept.

Figures 1,2 and 3 of the Luxfer Prism glass tile with ornamental lines that take the form of circles, arcs of circles, squares, and the like, arranged concentrically around the center and interlacing or overlapping each other, taken from the approved patent application which is dated December 7, 1897.
