Burning cup is a product which helps prevent a beverage from cooling down due to heat release to outside. The
sodium acetate contained in the inside of this cup can keep the heat of beverage. This liquid solution breaks the
balance of liquid state by even tiny impact and hardens it solid, and at this time generates heat momentarily.
This heat allows the temperature of the beverage in the cup to be kept for a period of time consistently, the heat
contained in the beverage is delivered again to the outside sodium acetate, and makes the solid into liquid, so
permanent use is practicable.
