Mug

A mug is a type of cup,^[1] a drinking vessel usually intended for hot drinks such as: coffee, hot chocolate, or tea. Mugs usually have handles and hold a larger amount of fluid than other types of cups such as teacups or coffee cups. Typically, a mug holds approximately 240–350 ml (8–12 US fl oz; 8.3–12.5 imp fl oz) of liquid.^[2]

Mugs typically have a straight-line profile, either perpendicular or flaring. But this is not defining for the form, and a curving profile is possible. But a single vertical handle is essential (otherwise the vessel is a beaker), as is the lack of a matching saucer.^[3] 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 made of pottery, while most modern ones are made of pottery materials such as bone china, earthenware, porcelain, or stoneware. Large mugs, typically made of metal or pottery and used for drinking beer, are likely to be called tankards. Some mugs 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 and fan art, which are fired onto the mug to ensure permanence.
