찻주전자, or "tea kettle," is a vessel used for boiling water and steeping tea. Typically made from materials like stainless steel, glass, or ceramic, it features a spout for pouring and a handle for easy lifting. Some models come with a built-in whistle to signal when the water has reached a boil. In many cultures, including Korea, the 찻주전자 plays a significant role in the tea-making process. It is often used in conjunction with teacups and tea leaves to prepare various types of tea, enhancing the experience of enjoying this popular beverage.
