Sonoran Beaver Posted February 19, 2021 Report Share Posted February 19, 2021 Hoping that someone can teach me about these. Are they both Master glass? .640 and .630 Link to comment Share on other sites More sharing options...
Ric Posted February 19, 2021 Report Share Posted February 19, 2021 Akro and Master made the majority of brushed patches you'll see. In my experience, Masters usually have a pretty "pointy" (or tighter U) type seam on one pole than Akros and they may have more going on inside of the marble. In addition, you can often feel the seam on Masters with your fingernail, which is a less common on Akros. The ones you are showing here look like Master Marbles to me.

cheese Posted February 20, 2021 Report Share Posted February 20, 2021 Agreed, Master brushed patches. If pics might help you with them, here are some of a lot I got not long ago, mostly brushed patches. Link to comment Share on other sites More sharing options...
