Russian Cups, also known as Podstakannik, are traditional glass holders used in Russia to serve tea. These cups are typically made of glass and are held in place by a metal frame, which often features intricate designs. The frame not only adds an aesthetic appeal but also protects the drinker from the heat of the glass. The use of Russian Cups dates back to the 19th century and is associated with the cultural practice of drinking tea on long train journeys. They are often found in trains and restaurants, symbolizing hospitality and the rich tradition of tea drinking in Russia.
