This coaster features our Spirit of Detroit sculpture design.  Multi-functional little art pieces make great gifts, and are a great size (and price) for buyers. This design is perfect for residents and tourists alike. • Wispy white glass, printed in mint and yellow glass enamels • 4" square, with rubber bumpons on bottom • Dishwasher safe • Handmade in the USA Coasters are screen printed, fused glass.  Glass is cut, and screen printed by hand with fine glass enamels, then fused overnight to 1415 degrees in a kiln. Each piece is made by artist Laurie Freivogel in her Oak Park studio. This design is part of a series and has other matching housewares!
