Humanity has invented many varieties of dishes, and each item has its own characteristics and purpose. The difference between a plate and a saucepan is obvious. The difference between a cup and a mug is not so straightforward, but it does exist.
Both the cup and the mug are intended for drinks, but these vessels look completely different. As a rule, the cup has a shape close to hemispherical, and the circle is in the shape of a cylinder or truncated cone, the walls of the cup are thin, and the walls of the circle are thick. The difference between a cup and a circle is not limited to the shape, they also differ in the way they are used.
The capacity of the mug is quite large - at least 300-350 ml. There are also larger mugs - half a liter or even a liter, of which beer is usually drunk. The mug always has a handle that you can grip with at least three fingers. Some mugs (especially beer mugs) have lids.
They only drink from mugs, but never eat with a spoon. Drinks can be either hot or cold. You can drink everything from a mug - tea, coffee, juice, fruit drink, and kvass, and compote, and broth, but it is not customary to pour soups with dressing into a mug.
Mugs are made from various materials: glass, ceramics, porcelain, wood, aluminum, iron.
A saucer is never attached to the mug; it is placed directly on the table. This feature, as well as the large volume, makes the use of the mug very "democratic", it is often used to quench thirst in between times. Mugs are usually sold one at a time.
Cups are more varied in size than mugs, their volume ranges from 100 or even 50 ml for coffee cups to 300-400 for bouillon cups. But in general, cups are smaller in volume than mugs: there are no liter cups or 200 ml mugs.
In most cases, the cup has a handle like the mug, but not as wide. There are bouillon cups with two handles, as well as cups without handles - bowls.
Unlike mugs, it is not customary to drink cold drinks from cups - they are intended for tea, coffee, broth, dressing soup or puree soup. If soup, broth or chocolate is served in a cup, they do not drink from the cup, but eat with a spoon.
The range of materials from which cups are made is not as wide as that of mugs: porcelain, ceramics, earthenware, glass. There are no wooden or metal cups.
A saucer is attached to the cup, usually it is sold along with the saucer. Very often, cups and saucers are sold not one by one, but in the form of a service, which also includes other items - for example, a teapot or a coffee pot, a sugar bowl.
A cup and saucer is more associated not with everyday use, but with a feast, a beautifully served table.
