The cups of the Japanese tea ceremony are quiet companions of slow Sunday afternoons in many homes. This two-piece set is made in China in the Japanese Tetsubin style, in cast iron. Each cup holds 120 millilitres of tea – just the amount worth holding in a single calm sip. The total set weight is 555 grams, giving the soothing, weighty feel in the hand that belongs to iron-teapot culture.
The character of Tetsubin cups
Tetsubin is a traditional Japanese teapot style that has been used for centuries. These cups are the matching companions of that style. The visible iron exterior is cool to the touch, heavy, black – while the interior is finished with a glossy enamel that prevents the iron from affecting the taste of the tea. Many families order matching cups together with a Tetsubin teapot, so the set remains a unit.
How it keeps the tea warm
Iron warms up slowly and cools down slowly. As you pour hot tea into a pre-warmed cup, the iron absorbs the heat and releases it gradually. This means the tea stays at a pleasant temperature sip after sip, rather than cooling abruptly. Compared with a regular ceramic cup, a Tetsubin cup keeps the warmth for noticeably longer – ideal for longer conversations or slow reading.
How to use it for the best flavour
Before use, it helps to warm the cup with hot water: fill it with boiling water, wait 30–60 seconds, then pour it out, and only then pour in the tea. The enamel inner layer does not transfer any iron taste to the tea, so green, black or herbal teas come through cleanly. Avoid strongly acidic teas (lemon-based blends), as they can damage the enamel over time.
Cleaning and care
Wash the cup by hand with lukewarm water and a soft sponge. Do not use harsh detergents and never place it in the dishwasher – this can ruin both the enamel and the iron exterior. After cleaning, dry it with a kitchen cloth and do not leave it sitting in water. If small, faint marks appear on the iron exterior over time, this is natural – the object begins to develop a patina.
Who will appreciate it
We recommend it to you if you enjoy a slow tea ritual and value the weight and natural materials of objects. It also makes a good gift for a couple – for a birthday, a wedding anniversary, or simply as a meaningful gesture to a friend. The set pairs with a separate Tetsubin teapot, so the tea ceremony feels complete.
