Original Message: Could it be like the grey core in old powder glass beads? |
---|
I'm reluctant to fracture one of them to compare. In fact I only have one, and it's not a very large one, so maybe it will make the ultimate sacrifice. I'll wait for more input before I destroy it. If anyone has a powder glass bead with a gray core that is already broken or badly damaged, and you’re willing to donate it to bead research, please let me know, or just post a good macro photo of the fracture surface.
