A terracotta cup is typically made from fired clay, known for its rustic, earthy appearance. The material is often reddish-brown due to the natural iron content in the clay. The surface may be smooth or slightly textured, depending on the finish, and is sometimes left unglazed, showcasing its natural porous properties. Terracotta cups often have a simple, handmade feel, with some featuring hand-painted or stamped designs for added character. These cups are commonly used for decorative purposes. The natural insulation properties of terracotta help keep drinks warm for a longer time.
