Shabu-shabu Pot DELICO 24 cm Stainless steel It appears to be unused, but it may have been used a few times. Although it's difficult to say for sure due to long-term storage, it's in good condition with little sign of use. Please refer to the following regarding the chimney shape of the shabu-shabu pot: 1.1. Remnants of its role as a vent in the past In the days before gas stoves, people cooked over charcoal fires using shichirin (small charcoal braziers). If a pot was placed on top and sealed, there would be no airflow, and the heat would weaken. It is said that a chimney was placed in the center to create an airflow and serve as a vent, and this is a remnant of that. 1.2. To maintain a constant soup temperature Shabu-shabu lowers the temperature each time cold meat and vegetables are dipped into the soup. To prevent this, pots made of copper, which has high thermal conductivity, are used, and the chimney increases the surface area where the pot and fire come into contact, helping to keep the soup from cooling down. 1.3. To prevent hands from getting hot when doing shabu-shabu With ordinary pots, heat escapes to the outside, so your hands get hot when you shabu-shabu ingredients. Shabu-shabu pots have a chimney in the center, which allows heat to escape from the chimney, preventing your hands from getting hot.
