Warm stone / Heat preservation

Warm stone
Warm stone

When we drink hot tea in a cold day , the temperature always run off and get cold, and it’s very inconvenient to heat. So I design the Warm stone to put it into the tea, in the beginning, the stone will absorb the heat and focus inside, when the tea’s temperature decrease gradually, the stone will became exothermic to maintain the temperature of tea, not get cold too fast.
