Hi all,

I have a 90s USA lamp with some strange flow. I have uploaded photos below;

The majority of the melted wax tends to stay in a dome at the bottom, while releasing little "bubbles". It stays at the bottom the entire time, even though there is still some minimal flow. I tilt it side to side, and the wax at the bottom moves around- it's almost like the wax stays with the coil.

The issue may not be the heat output.. I leave it on for 4 hours and it flows this way. I left it on overnight, and it flows this way.

The issue may also not be the wax, because I have seen it flow optimally for a little a couple times before. I have even used a hairdryer to get more of the wax up, which had a small effect.

- I tried with and without a heat ring

- Correct bulb is being used

- Coil is always in correct position

Because of the flow issue, the lamp appears awfully dark in person.. so I have been wondering, how can I correct this flow?

Why is the wax behaving this way? Is there a water density problem? Is there any way to get it up and moving correctly?  Any help would be highly appreciated.
