The very best Lava Lamps for buildings
If you want a party novelty item that all your friends will find fascinating, you should contemplate
getting a lava lamp.
A lava (or Astro)
floor lamp
is a cosmetic lamp made of a clear glass vessel that contains liquids that
move in such a way as to suggest the action of lava erupting from a mountain. The inside of the vessel
contains colored wax floating in a clear liquid. This liquid is heated from under by a light bulb, which
decreases the density of the wax, causing the wax to break apart and rise. Once the wax reaches the top
surface of the liquid, it starts to cool and eventually sinks to the bottom, to start the process over again.
You can’t use a pure water solution for a lava lamp, because water is denser than wax; the wax would
never rise, no matter how much it was heated. So carbon tetrachloride, which is denser than water, is
added to the water. The carbon tetrachloride combines completely with the wax, raising the density of
the wax to the point where it is just barely denser than water; this enables the wax to rise without
having to be heated very much.
Wax expands more when it’s heated than water does, so as it heats, the wax soon becomes less dense
than the water, causing the wax to rise. The wax also becomes fluid, causing it to break up into lumps as
it rises. But the top surface of the water, being the farthest from the light bulb, is the coolest section, so
the wax eventually cools and sinks to the bottom. A coil of metallic wire at the bottom of the vessel
serves as a surface tension breaker, consequently causing the lumps of wax to recombine into a single
ball after the wax falls.
If the lava

is stored in a cool room, it can take up to three or four hours to heat the lamp
up to the point where the wax will rise. Even if you store it in a warm room, it still might take an hour to
warm it up enough. Don’t shake the lamp, though, or the liquid will get cloudy.
Certain varieties of lava lamps are prone to not working. If you’ve got a dud that doesn’t heat after a few
hours, there’s a trick you can try that on occasion works. Using oven gloves, pick up the heated glass
vessel from its base and place it on a flat, even surface that can handle the heat. Gently spin the vessel,
which will allow the wax to settle onto the wire coil. Then return the vessel to its spot over the light
bulb, and your problem might be solved.

There are various recipes for lava
globes
lamp liquids. Most contain water, mineral oil, paraffin wax and
carbon tetrachloride. Some recipes call for alcohol, but these can be explosive under certain conditions.
Carbon tetrachloride isn’t flammable, so it lessens the likelihood of an explosion.
Make certain to use the exact wattage and kind of bulb prescribed. Usually, the bulb is either a halogen
or an incandescent, between twenty-five and forty watts. Too big of a bulb can prove hazardous, and
too little of a bulb won’t create enough heat to raise the wax.
