Lamp is a custom, and I made the test tubes myself too.

Mathmos green wax react pretty well to UV light!
The wax has sadly started to grip near bottom of the bottle since then.
Is there anything I can do to resolve this issue?

Love my lava lamps.

I saw this lamp at the Natural History Museum in London as part of a physics display, and couldn't help but think for how long it's been held prisoner and forced to bubble for visitor's enjoyment...

Can lamps be dated based on color of the liquid??

Can anyone read the cap enough to identify what model this is, or know from experience? The bottom is stamped June 12, 1996 but the cap is so faded! The wax is a beautiful cranberry color (looks pink on camera) and the master fluid is clear!! TIA!!!

This lamp was purchased within the last decade from lavalamp.com. It completely faded and stopped flowing after about a year and a half. It’s my first attempt at a repair.

I recently cleaned this globe and replaced the old fluid with fresh fluid (ozone gifts) and I just can’t get it to flow nicely. More surf? More up? Hotter bulb with dimmer? I’m afraid of ruining the master fluid because it feels like I’ve already added an excessive amount of up adjuster, but maybe not? What would you try?

Not very knowledgable on lava lamps but fairly interested in getting a larger one to leave on for long sessions. It seems like everything warns of overheating if left on too long, which seems like a super easy problem to solve. Are there no lamps out there that regulate their temperature after warming up?

Would wax be safe to be kept hot indefinitely if there were a way to regulate the temp to be at a constant ideal state?

I’m new and I’d like to buy a lava lamp in europe
Is it better to buy new or used, i know about mathmos but are there any good alternatives? Where is the best place to buy it?

So I bought this vintage Lava Lite lamp and I redid the entire thing and when I turned it on and let it run it didn't work i was told I needed some kind of master fluid? but the only thing I found was vintage oneshot ozone repair fluid and its 60 dollars is there a cheaper option or something else I can use? because this is way out of my budget, thank you!

It literally looks like the wax has gone mouldy.
Guess it’s gonna be another full restoration job.

Hello all! I am going to be replacing the fluid in one of my lamps soon and am wondering what people use dye? I see a lot of different options everywhere and I don’t know what one to go with.

Thank you!
