Here's an introduction to a glass art piece I purchased at an American antique market. Style: This artwork is art glass made on Murano Island, Italy, and is from the Mid-Century Modern style (1960s-70s). 16.5 x 15.5 x 6.8 cm * Features: Bullicante technique: Characterized by controlled air bubbles trapped within the glass. * Shape: Molded to resemble the shape of a four-leaf clover or a shamrock. * Uses: Generally used as an ashtray or candy dish. It's a vibrant emerald green or lime green color.
