Heat can be transferred in three ways: conduction, convection, radiation. In a vacuum flask, conduction and convection are greatly reduced through a vacuum (hence the name!) between two glass layers, whereas radiation is greatly reduced by the mirror coating on the same glass. As a result, heat takes much longer to get out - or in, since you can also keep cold things in a vacuum flask.Note that no vacuum flask will keep things hot (or cold) indefinitely; it simply takes much longer for hot things to cool down, or for cold things to heat up.

A cup of hot tea can potentially cause more harm than a fire spark because the liquid can cover more surface area and stay in contact with the skin longer, leading to more severe burns.

Additionally, the heat from the hot tea can penetrate deeper into the skin compared to a quick contact with a fire spark.
