I hope this is wrong, but I think bubbles and tiny globules mean it's been overheated/overused at some stage. They are pretty old fills by now, even with new MF...
My Lunar glitterball has them, in quantity; an expert tells me they won't go away, but I've noticed if I run the lamp very slowly (dimmed) there are fewer bubbles.
Yep your other one looks a beauty, it's great goo isn't it?
one of my faves , ive run it up for 2 hours im hoping they will settle back down into a solid lump but its such a thick liquid
im thinking of runing the liquid through some tights to try and catch the bubbles ?
used to get them even from new, problem is the fluid was so thick its hard for them to sink down and re-connect with the main lava
I think the small globs/bubbles are normal for glitterball bottles that have been run often.
I have a silver glitterball Lunar bottle that starts off clear but soon after it starts flowing the little blobs/bubbles start forming and after a few hours the entire globe is full of them.
At first I did not like this at all, however over time I have come to like it as the lamp looks like an exotic lava/glitter hybrid now :)
