Rocks glasses have an exciting history. Prior to the 1970's they were predominantly used for cocktails consisting of gin, whiskey, or rum. However, these short tumblers are used for a wider variety of cocktails that change according to customer taste. Traditionally rock glasses are called "lowball" glasses when they hold an unmixed liquor "on the rocks", or over ice. For most of their history, rock glasses have held between eight and twelve ounces. Their heavier bottom helps prevent tumbling over and spilling drinks.
