Alessi’s Ossidiana, designed by Sicilian architect Mario Trimarchi, is a modern espresso coffee maker with a sculptural, faceted form inspired by obsidian, also known as lava glass. The modern moka pot is cast from aluminium and makes 3 cups of espresso at once. Its handle and knob are made of thermoplastic resin. In 2016, Ossidiana won the prestigious Compasso d’Oro design award.
