These lovely handmade glass vessels get their distinctive color from crushed quagga mussel shells. Quagga mussels are an invasive species in the US and most of Europe, having originated in Ukraine. The mussels tend to clog pipes and must be removed, but they aren't fit to be eaten, so they end up in landfills by the ton.
Glass artist Lulu Harrison has spent years studying and experimenting with waste products in order to turn them into beautiful new objects. Her Thames Glass project uses artifacts removed from pipes in and out of the River Thames such as quagga shells, local sand, wood, and metal to make glassware and tiles. She collaborated with glass blowers Sacha Delabre and Rosie Power to make the Thames Glass collection, which will be shown at the Design Museum in London June 24th through August 25th. The museum has recently awarded Harrison the Ralph Saltzman Prize for the project.
