Lava lamp – a fire hazard

When burnt for continuous 8 to 10 hours, lava lamps get overheated and can cause a fire hazard, so it is not safe to use it for domestic purposes. Overheating of the lamp may depend upon the bulb and the brand of the lava lamp. Moreover, due to excessive heating, multiple moving blobs can join to form a big blob inside the lamp. This big blob can not then transform back to the smaller ones of varying shapes.

Lava lamp

Lava lamps are named so because of their lava-like appearance. But inside the lamp, it is just a substance and the water. This substance slips against the water inside the lamp. Above the lamp, there is a machine fixed that sucks up the material giving it the appearance of the real looking lava.

At their peak, more than seven million Lava Lamps were sold around the world each year,

The lava lamp is a lamp used for the purpose of decoration. It was invented by a British named Edward Craven in 1963. It is an electric lamp containing a thick liquid inside it and a vibrant colored wax sailing around it. Time to time, this waxy material goes upwards, downwards, and suspends continuously, and change in shape occurs.

A conventional lava lamp is a standard halogen lamp that heats the glass bottle while the liquid inside the lamp may consist of water and a mixture of paraffin oil and mineral oil.

When the lamp is burnt for 8 to 10 hours continuously, it may get overheated and cause a fire hazard.


The principle behind the construction of lamps is “like dissolves like.” In making a lava lamp, two liquids of opposite nature are used. When two immiscible liquids (water and wax) are put together in a container, being different in nature, they do not mix into each other. This led to the making of these innovative lamps. Radiation is the transfer of heat through energy waves, this is very similar to sun heating the earth’s surface, just like how a light bulb radiates heat to the bottom of the lava lamp.


The lava lamp has a bulb at the bottom. This bulb acts as a heating source. It heats up the wax, making it a bit heavier than the water, and it starts moving in an irregular pattern and eventually floating above the surface of the water. When the wax reaches the top, it becomes denser and ultimately sinks down. This erratic movement due to heating and cooling of wax shows how the lava lamp works.
