The use of art glass in the Dana-Thomas House (Springfield, Illinois, 1902) is the most complete and lavish of Wright's career. Specially prepared panels were used in the suspended lamps, wall sconces, and table lamps throughout the house as well as in the stained glass windows of the house and gallery. Wright himself admitted, some fifty years after these works were done, that of all his glass designs, those of the Dana-Thomas House were by far the most resplendent, as well as the most costly.

Many of these glass designs take nature forms for their inspiration. For example, the suspended lamps in the dining room were derived from the shapes of luxuriant butterfly wings. The transom glass over the front door includes several butterflies with overlapping wings, and the sumac windows in the dining room echo midwestern shrubs.

The wall sconces and table lamps, however, were designs created as pure geometric abstractions. Their straight-line patterns were easily adaptable to the glass maker's craft. Whether casting light upon the table or into the room, they also radiate deep autumnal shades of color, creating a warm glow within the interior of the building.

UL approved, two 40W incandescent bulbs. Shade is colored iridescent glass and black patina brass. Base is polished brass.
