Cast iron teapots have been used in the popular whole-tea leaf ceremonies in Japan dating back to the 17th century. Primulas exquisite cast iron teapot designs are inspired by the traditional Japanese culture and capture the original function of preserving heat and evenly infusing the natural nutrients from your loose leaf tea. Our enamel interior coating prevents oxidation of the cast iron, preserving the beauty and durability of your teapot. So enjoy the splendor of our beautiful designs and the magic of a wonderful tea experience. At Primula, something extraordinary is brewing.
