Tammy Posted December 25, 2020 Report Share Posted December 25, 2020 Hello. I am not a collector but have become interested as of late. I was looking at this marble through a magnifier & noticed the circle marks around the entire marble. Is this pontil marks? If so, why so many? Thanks.

I'llhavethat1 Posted December 25, 2020 Report Share Posted December 25, 2020 I believe they're referred to as "cold roll" marks from the rollers not being at the correct temperature to smooth them out. A lot of industrial marbles had this feature (how the marble looked wasn't as important) . Link to comment Share on other sites More sharing options...
