UV swirls/slags

These may be tricky to ID because of their condition. The last two images are backlit.

Yep—these are tuff ones but I bet they glow like heck—pretty cool that.
The upper left may just be a swirl.
The upper right shows a nice big CAC like cutoff in the last image.
The lower left is either a Peltier or an Akro imho.
The lower right---no clue.
I looked and gave an opinion, I hope to see some more opinions.
Marble—On!!

Cac or mfc?  I thought mfc had the 9.

I agree, this looks like a nine.

Research MFC with nines --or others that were handgathered and you will get a better idea.

Many slags have "nines" and many different companies produced them.

A whole lot of them were machine made--it just they way of machine made marble production.

You will get a feel for them once you have seen enough of them.

I know that you will get there. Experience and "in hand" will tell the tale.

Keep on collecting and keep on learning---this is the way.

Marble--On!!
