Coffee mug

A mug is a type of cup typically used for drinking hot beverages, such as coffee, hot chocolate, soup, or tea. Mugs usually have handles and hold a larger amount of fluid than other types of cup. Usually a mug holds approximately 12 US fluid ounces (350 ml) of liquid; double a tea cup. A mug is a less formal style of drink container and is not usually used in formal place settings, where a teacup or coffee cup is preferred. Shaving mugs are used to assist in wet shaving.

Ancient mugs were usually carved in wood or bone, or shaped of clay, while most modern ones are made of ceramic materials such as bone china, earthenware, porcelain, or stoneware. Some are made from strengthened glass, such as Pyrex. Other materials, including enameled metal, plastic, or steel are preferred, when reduced weight or resistance to breakage is at a premium, such as for camping. A travel mug is insulated and has a cover with a small sipping opening to prevent spills. Techniques such as silk screen printing or decals are used to apply decorations such as logos or images, which are fired onto the mug to ensure permanence.

Wooden mugs were produced probably from the oldest time, but most of them have not survived intact.

The first pottery was shaped by hand and was later facilitated by invention of the potter's wheel (date unknown, between 6,500 and 3000 BCE). It was relatively easy to add a handle to a cup in the process thus producing a mug. For example, a rather advanced, decorated clay mug from 4000–5000 BCE was found in Greece.
