This borosilicate glass mug was designed by partner Josh Corn as an invitation for coffee drinkers to learn and play with various recipes. Measure ingredients and change the proportions of espresso, milk and water using the handy indicators printed on the outside of the mug. Recipes include espresso, macchiato, cortado, caffé au lait, Americano, flat white and cappuccino. Currently available for purchase at the MoMA Design store.
