Soup vessels are containers used to store and serve soup. Two common examples of soup vessels are POTS and tureens. POTS are four-letter vessels that are typically made of metal or ceramic and have a lid. Tureens are seven-letter vessels that are usually made of ceramic and have a lid and handles. Both POTS and tureens are used to store and serve soup, but tureens are often more decorative and ornate than POTS.
