- The Lava Lamp was invented in 1963 by Edward Craven Walker, and produced in Poole, UK by Mathmos (known as Crestworth until 1992) - the company that he founded. Many other companies worldwide now produce their own versions, but the Mathmos types are the originals.
A 40 Watt incandescent reflector golfball lamp in the base provides the illumination, along with the necessary heat that is required to liquefy the wax compound that is positioned at the bottom of the Lava Lamp bottle, within a coloured oil-based liquid. Notice that the wax forms something resembling a stalacmite as it warms up. Once the wax is liquefied, its lower density causes it to rise towards the top of the bottle in random blob shapes through convection; however, once at the top, the wax cools, and the density increases, causing it to return to the bottom, and the cycle repeats constantly until the lamp is extinguished, when the wax then cools, and solidifies at the bottom of the bottle again.
This particular example uses a bottle containing yellow oil and red wax, but there are many other combinations.

What colour combination is this? Thanks!
It's yellow fluid and red lava!
I'm curious, Have you ever successfully acquired street lights from highways England by asking them directly? Or are their lanterns out of reach.
I haven't dealt with them myself, but I believe that some of the other collectors were successful in saving MA 60s that came from the M1 in my patch, so it probably can be done.
I've also just remembered that the enormous twin 180 W SOX catenary lanterns from near the M25 interchange were saved too (though I had to decline one myself - taking something that size on would definitely mean that I would have to sleep in the garden!), so it doesn't seem as though they have a blanket "no" policy.
