The problem below has been fixed. Please see the second page for my new question.
I bought this lamp (my first) at an auction. I had no previous knowledge of lava lamps except that I knew they worked because of thermodynamics and that they were cool. The lamp is a Century, I'm pretty sure, but I have some questions.
The first one is the lava lamp, the second one illustrates the 'chunks' in the lava. The outset has been adjusted in Photoshop to bring out the flakes.
When I turn on the lamp, it heats up fine, but then a large blob starts accumulating at the top because bunches of lava merge together, and does not go away (it seems like surface tension holds the blob there to the top of the liquid). I read here
that the lava should only be able to merge when at the base, and not at the top (at least not much). How can I get the blob to go away (see below for possible causes)?
Also, if you look at my second picture, the blob at the top is full of 'clumps' of whitish flakes. These are not melted obviously, because they actually cause spikes to poke out of the blob at the top. I have looked all over for explanations of these, and can't find any. Can I do something about them? They are like this guy described here
Here are the lamp specs:
Model: Century 102 (found that out by looking around)
Bulb: 60W unfrosted (we replaced the original bulb, was to cold for our house, but installed a dimmer switch which is set below max.)
Height: 15in approx.
Color: red wax/clear liquid.
Room temp: 62-65 F (I know, we run our house cold).
My dad suggests the following:
1. empty liquid.
2. melt lava and swirl to homogenize it.
3. filter liquid to remove cloudiness.
4. rebuild lava lamp.
Will this take care of the problem?
If anyone could help, that would be great.
I turned the lamp on this morning and after heating up, the wax on the bottom formed a big cavity underneath and basically popped, sending the bottom layer of wax away from the coil. Now it won't run. Is there anything I can do about this, or is the lamp a lost cause?
Now the wax is running, at least in little bubbles. How can I keep this from happening again?
