I decided to test and see if a new coil in my China clear/white 52oz would fix it's issues. What do you know, it does! I thought I would share the spring type I used and some photos in case anyone out there wants to give it a go. Well worth it. My lamp actually flows now. Before, it would not attach to the spring and it would just blob up at the bottom and stay there. Even after cleaning the cheap coil inside.
Now, it's what a lava lamp should be! :D Thanks to all here for the wealth of information and knowledge. Without it, this would not have happened.
