glass
A cup used to serve ice cream. In restaurants, they're usually made out of glass, typically short, footed with a wide bowl. For convenience stores and ice cream parlors, they're designed for eating on the go, made out of disposable paper and may have an ice cream spoon attached to the cup.
Do not confused with parfait glass which is typically much taller and with narrower rim.
