Porcelain cups are a popular choice for serving tea or coffee due to their delicate appearance and durability. However, there are various synonyms that can be used to describe such a cup. It may be referred to as a china cup, which is another term for porcelain, or a ceramic cup, as both porcelain and ceramics are made from clay and are fired at high temperatures. Another synonym could be a tea cup or coffee cup, depending on the beverage that is being served. Additionally, the cup could be described as an antique cup, if it is a valuable and rare piece. Regardless of the synonym used, a porcelain cup always adds a touch of elegance to any table setting.
