When I was a silk screen printer (another story) I used a lot of
"fumed silica" to thicken my inks. It is a very lightweight powder,
and I understood it to be essentially frothed glass.

I don't know how well it "packs" or settles, but I suspect it might
be a solution for your globes. I was always careful when handling to
avoid breathing the dust it is a very fine powder. I still have a
bucket of the stuff if you would like to try it. You might find it
at a large supplier of inks for silk screen printing, or contact the
manufacturer for a coarser product.
