I made up a few colorful names to describe a problem I'm having with one of my lamps. I just started collecting last week when I got my first 3 Lava Lite lamps (two 32 oz Midnights and a 52 oz)
First off I've labeled the phases my lamps go through to be a bit more clear (plus, I don't really follow the other stages I've read so far).
Stage I - Convection. This stage begins when the switch is flipped and the lava begins warming
Stage II - Eruption. Lava travels up the side of the globe and forms in the top of the globe
Stage III - Destruction. The lava mass formed in stage II falls to the bottom of the globe
Stage IV - Globulation. Globules form and travel to the top of the globe. They cool and fall to the bottom of the globe. They have not reached full size and the lava mass at the bottom is not completely melted
Stage V - Flow. This is where the lava lamp hits its stride. Large globules rise and fall in a smooth motion
a) Glob flow - the best and most captivating flow
b) Hula Girl flow - attached at the bottom, but dancing like a hula girl
c) Snake flow - attached from top to bottom, usually a short state
d) Blinky - Maybe starting to overheat? Named after Pac Man's nemisis, not an
unmoving glob at the bottom, taller but not much better
Stage VI - Decline. Flow will decline in one of three ways. All of these spell less or no motion
Okay, back to my problem, one of the Midnights (the yellow lava, blue liquid) must have been shaken and/or the wax has separated from the coil. The wax is still partially separated from the coil unlike my other lamps where it fully engulfs the coil.
The lamp starts to experience what looks like tens or hundreds of individual caviar eggs floating around in the liquid. Or a million stars (thus the reason I call this effect nebulation, like a nebula). The liquid is not cloudy, but is filled with all these dots of wax. It is not apparent in the earlier stages, but as Stage IV begins, these little pellets emerge and don't go away until the lamp has cooled. They cannot be reintroduced to the other wax as they will not merge and remain singular due to a protective "shell" that is a constant liquid barrier between the dots and the other wax globs.
I can only speculate as to the cause as the lamp was purchased second hand. I would like to try to fix it if possible by non-invasive means. I enjoy the color combination and the movement of the wax is, well not as good as the others. I'd rather not have to do a drain and fill if possible. I've changed light bulbs, swapped bases and the blue/white does great whatever I do, the blue/yellow doesn't seem to stay in Stage V for very long (it goes Blinky on me and stays that way) and has this nebulation problem. Room temp has been 75.4 F - 76.2 F and the other two lamps work fine.
Any suggestions as to the cause or more importantly, the solution for this effect?
