A thermal carafe is a container designed to keep beverages hot or cold for extended periods. It typically features double-walled insulation, which minimizes heat transfer, allowing liquids like coffee or tea to maintain their temperature without the need for a heating element. These carafes are often made from stainless steel or glass and come with a secure lid to prevent spills. They are popular in households and offices for serving drinks at gatherings or during meetings, providing a convenient way to enjoy beverages without frequent reheating.
