Solid alcohol is not solid alcohol (the melting point of alcohol is very low, it is-1 17.3℃, so it can't be solid at room temperature), but industrial alcohol (ethanol) is added with coagulant to make it solid. When in use, it can be lit with matches. When burning, it is smokeless, non-toxic and tasteless, and the flame temperature is uniform, and the temperature can reach about 600℃. It can burn for more than 1.5 hours per 250 g, which is more economical, convenient and safe than using electric furnace and alcohol furnace. Therefore, it is an ideal convenient fuel.
