Just Another "from scratch" Project

[Anil Celik]

Hello

Like everyone involved in the lavalamp hobby, I have been following your forum for years, but I have only just become a member, so first of all, thank you guys. For about a month I have been trying to build a lavalamp from scratch. I made several unsuccessful attempts here with many different materials (soy wax, waxes with different oil ratios) and on my 7th attempt I managed to make a lavalamp using paraffin wax, PERC and microcrystalline wax.

My main issue is this. When I first fill the lavalamp, the specific gravity of the wax seems correct, meaning the wax stays at the bottom. However, when the lamp heats up, a blooming effect occurs, just like in my original lavalamp, but this time it happens far more intensely. As the wax melts and tries to rise, it lifts all the wax sitting at the base of the lamp and pushes it upward, breaking the contact between the bottom and the wax. Because of this, the wax never fully melts and turns into a thick blob that gathers in the middle and upper parts of the lavalamp, as you can see in the photos I attached. What do you think I might be doing wrong?
