Today I saw this WONDERFUL Steve Keister Terra Cotta Ware at Artware Editions.
This hand-signed series of wares includes shot glasses, cups, tumblers, vases, and chips and dips bowls all sporting vivid, food-safe glaze over exposed terra cotta.

Keister casts from pre-existing forms culled from packaging detritus or recycled materials. The forms from this new line derive from voids or cavities found in styrofoam cartons and plastic bottles.
