Astro gone wild...

I'm afraid I tinkered too much with this one: After heating up the wax builds lots of small bubbles, wandering around very slowly, without merging again.
The Lamp has enough surfactant and even a coil, but the blobs stay apart. When turning out the light it takes half an hour and the wax is combined in one block again :-)

Comment by Claude J on September 22, 2017 at 5:09am: Sounds likes lots of experimentation going on.

Density is certainly not the issue.

Surface tension is

It might be best to just change the fluid, Water bath super-heat the goo, and start over.??

Comment by Peter Panussi on September 22, 2017 at 5:04am: Well, I tried a dimmer, but the wax immediately reacts like on the picture, as soon as it's melted.

I think the wax somehow changed it's characteristics. It's an old lamp. When I purchased it, it was very cloudy, I changed the liquid several times, used different surfactants, dyed the wax (was very pale), and now the surface tension is gone mad - once melted it never merges again...

Looks overheated

Do not know about Mathmos temps, but LL should be @125 degree F

Comment by Tribble on September 21, 2017 at 4:05pm: Would a dimmer help? Mine does that if I leave it on all day, I know, bad practice on my part but sometimes I fall asleep watching the flow. lol

Comment by Peter Panussi on September 21, 2017 at 11:38am: And it's not about water density: Changing the concentration of propyleneglykol doesn't effect the bubbling and the very slow movement
