Ghost core or Bubble core?

[disco005]

 

I think I've heard them called by both names, is that right? 

And if anyone has any more examples, I'd love to see them!

Thanks! -Jess

Its a coreless swirl.  The presence of fine bubbles are sometimes referred to as a ghost core.  It caused by the first marvering of the initial core being uneven and the second gather doesn't adhere well.

Indian maglite w/ the common green transparent base glass and a ghost core and a few filaments also, still just a ghost core. I've taken a superb underlit picture of this marble I will download later, sorry for the graininess in this one !!

Ahhh, that makes sense, thanks Alan! 

That is a SOLID ghost core on that Indian Maglite, wow. Thanks for sharing your photo!

This is a little better, "sorry again for the grainy pic" yes the ghost core is from marvering, but the threads riding alongside the ghost core have color. The thinner lines have a yellow tint while the thicker ribbon has a white color, as if they adopted the colors from the outside ribbons. Never the less an uncommon core.

And sometimes it ends up that way in a more evenly spaced Latt pattern, sorry terrible pic (but should be evident) .  Speaking of marvering, I appreacite the marve-l of good cameras and photography skills when it comes to marbles say that 10 times fast
