The average shot glass is 1.5 ounces or 44 ml, while a pony shot is only 1 ounce or 30 ml. The glass is small and designed to hold a measure of liquor.
The first citation for the term "shot glass," according to the Oxford English Dictionary, was in The New York Times during the 1940s. Shot glasses come in many shapes and sizes. A shot glass is a popular souvenir or collectible due to the wide variety of pictures, advertisements, and other decorations found on them. A typical shot glass is made of thick glass so it does not break when one slams the glass down on the bar after taking a shot.
