Is a lava lamp supposed to get really hot?
Likewise, can you overheat a lava lamp?
Lava Lamp Use While it may be tempting to operate your lava lamp all hours of the day and night, this can cause it to overheat, which may make the colored blobs stop moving in an amoeba-like fashion. A lava lamp may overheat in eight to 10 hours, depending upon the bulb and brand of lamp.
Regarding this, how hot does lava lamp get?
Operating temperatures of lava lamps vary, but are normally around 60 °C (140 °F). If too low or too high a wattage bulb is used in the base, the "lava" ceases to circulate, either remaining quiescent at the bottom (too cold) or all rising to the top (too hot).
Lava lamps are not built to function 24 hours. It is vital that the lamp should be able to cool down from time to time in order for the ingredients to rest and retain its nature. You may use timers for a lamp in order for them to cool off in a certain period of time.
