German Slag?

[Leigh]

These marbles were in a group I purchased off of eBay that had a couple of German's in there. These aren't in the best shape as they rusted a bit because of the jar they were in. My first question is whether or not these are German and secondly, what is the best way to remove rust from a marble? I'd like to at least clean them up as well I can.  Also, what color would these be considered - seems like an extremely dark purple, but am wondering if there is a name for the color of this glass.

MFC IMO

I agree w/ MFC on the one specified. As far as the others all purple slags except I see two w a strange partial amber or brown looking cast or reflection on part of them ??

Thanks - the amber/brown is some rust. I am going to see if I can remove it off of them somehow. They all seem to match and were together, so I think they all must be purple MFC slags.

There may be some other makers slipped in there ?? Thanks for the quick reply I thought I was seeing things

I could be wrong, but they really do all look the same to me and they were in the same jar (hence, the rust on them).

Hmm, on second look they may all be Akro ?  Definitely no Germans

This photo on Joe's Marble's made me think MFC - https://marbleconnection.com/joemarbles/1Marble Picture Pages/15MFChristensen/MF Christensen 001/1 MF Christensen Large Pages/M.F. Christensen %26 Son 1-09.html

The larger is in poor condition, but these were in the same group as these purple ones. I can't figure these out either.

All amber slags, a good deal of them may be MFC, the biggest one especially, I'm not really a slag manufacture I.D person except to I.D. them as a slag (i.e. American or foreign)
