Trash imbedded in marbles

[Jjay]

The mib in the 11:00 o'clock position  looks to have a bug in the marble. 

The center mib looks like some type of trash in it.

The 12:00, 1:00 and 7:00 mibs seem to have an orange substance I can't make out. The Picts don't show it very good. I'm going to try and focus on the orange stuff to try and make it more visible.

what do you make of these. How old do you think that bug is?🙂

Could be "trash" as you say -- some kind of debris.

Could be colorant which didn't mix, or which somehow clumped out.  (Check green chunks for aventurine.)

Could be furnace brick -- chunks from where the glass is melted -- that is often (usually?) white.

The orange dots are a little different from what I'm used to.  Maybe there was a shard of glass on the roller and it got picked up?  

 

Do you mean literal bug? I'm under the impression that organic material wouldn't survive the 2000+ °F heat of the glass, even if it was a late addition as it was dropping to the roller.

not a bug. Trash in marbles is very common,  quite often it even gets crystally and folks call it aventurine. I have one aroung here somewhere that has more oven brick(one piece) than glass. I will try and find it.  Found it

Awesome.  That is by far the biggest chunk of furnace brick in a marble I have ever seen and it doesn't even look fractured.  So cool.

I appreciate the input. I guess I wasn't understanding that that was a piece of brick encased in glass. Wow. Thanks for the pict.
