The Tumbler

One of the consultants for the piece was Emilie Ledieu. She works in mosaics and has a lot of experience working with glass. She suggested "tumbling" the broken glass to make it like sea glass. The tumbler works like a cement mixer. You put water and sand in with the glass and plug it in. The longer you tumble, the smoother and more frosted the glass becomes. Some batches we tumbled for a few hours, some for a few days.
