Mug, it simply is the ability to heat the cup. Is generally made of ceramic or stainless steel with a vacuum layer of water storage containers made, the top cover, seal tight, packed in vacuum insulation layer can liquid water inside the slow cooling in order to achieve the purpose of insulation. Mug evolved from a thermos, thermos flask principle and as insulation, but it made for the convenience of the bottle glass. There are three ways to spread heat: radiation, convection and delivery. Silver cup holding cup of hot water can reflect the radiation lamps, glass lamps and the body of the vacuum cups to block the transmission of heat, while the bottle is not easy to stop the transfer of heat convection. Now the thermos, but also applied the principle of magnetic water is added at the bottom of the bottle and the bottle cap magnets, so that the water is magnetized. It is said that magnetized water has magical effect.
