Tetsubin
A Tetsubin is a traditional Japanese cast iron teapot, known for its durability and ability to retain heat. Often adorned with intricate designs, these teapots are not only functional but also serve as decorative pieces in Japanese culture. They are typically used for brewing green tea, enhancing the flavor through the iron's mineral content.
Historically, Tetsubin originated in the Edo period and were originally used for boiling water. Today, they are appreciated for their aesthetic appeal and are often collected as art. Many Tetsubin come with a removable inner enamel coating, making them suitable for direct use on a stove.
