I think I am close to solving my picture taking problems. It's been so hard in a 100-year-old house with such a wasted electrical grid that 75 W bulbs blow out if you don't think happy thoughts while toggling the light switch ... but I think I'm getting there. So here:
The majority opinion obtained through a smattering of emails has been that this is a Jabo with furnace junk stuck in it. I just cannot believe that though. That so-called junk is in each of these two marbles, and is practically the same shape and in practically the same location. It is a neat bar of glass which appears to me to be deliberately placed. It is translucent on one marble and near-opaque off-white on the other. Its position on both marbles is at or very near one end of what appears to be to be the single ribbon of color.
Does anyone have an example photo they could post of a Jabo that is anything like this?
Gracias,
Steph
