Right about the name slag. The typical manufacturer term for slags was "onyx". "Onyx" became a problematic name in the early 30's if I recall correctly -- because the true mineral onyx industry was trying to get protections against glass makers presenting their products as onyx -- but by then marble makers were mostly switched over to non-slags. Hmmm ... now I start an argument in my head about how Akro continued to use the name "onyx" into its corkscrew-making days well into the 1930's ... but I refuse to delete because most of what I said above is still true ... I think. lol The defendant in the FTC case was Gropper and the order to be very clear about what was meant by "onyx" applied to the Peltier marbles which Gropper was selling. https://books.google.com/books?id=y17ilneaDCAC&pg=PA274

I think odds are pretty good of Champion.

Looks like a lot of swirl for a 5/8" Jabo classic. I'll go with WV swirl of some kind.

Vitro Helmet on the bottom left. Green and yellow looks Peltish to me (upper right quadrant). Several Akro corks, some Pelt Rainbos, other Vitros, a Master brushed patch.

I would assume set. But I gotta leave it to one of the Jabo experts to say whether it all came from a single run and, if so, which run. I'm not recognizing it as the first Joker's but that was a long time ago and I wasn't as interested in Jokers as I was in Tributes.

Ah, and I see someone wrote a date on the bag. Interesting. That fits the marbles.

Yes, Vitros. At least some are Tiger Eyes, in a style which dates to the 1950's.

The brown is a bit weird to me, but much of the marble looks Alley. Size?

Proper Akro Indian Blanket, and a mint Akro Superman, mint Lifesaver. A lot more bumblebees.

Oy. At 1" that's a tough call. Could be a later (estimate 1950's) Master. The colors seem to be in the right general area. The orange peel is making me wonder if it might be European.

Could it be a weathered Master?

another vote for Peltier

I'm gonna guess FT isn't anyone famous.

I'm not sure we're seeing the whole picture. Do these marbles have two patches each?

yes, a pretty cool group

Not a popeye. That's an odd one. If it's machine-made, then I think it got it's twisting from being hung up in the machinery. But I'm not even sure it's machine-made right now. I think it's modern. Size?

With this view and that size, I'm gonna suggest Jabo.

I think maybe a slightly later MK Rainbow on #4. Maybe an Akro on #2. Not seeing MK there.

cool

Measurements are done with calipers. General advice is to avoid metal calipers, to protect the glass from scratches. Your bird is a "sulphide". It is a handmade marble made in Germany in the 1800's or early 1900's. The next two marbles are also handmades, from Germany, from that time range. I'm no good with giving the names of handmade styles. They can get very technical. The one that's not cracked might be a "divided ribbon core", but do not take my word for that! As well as I can tell with the views given, the black and white marbles is an Akro "corkscrew". From the 1930's. Below that is a stone marble. With that pattern it could be called a bullseye agate. It looks like it may have been someone's favorite shooter. (It has many hit marks on it -- which add character to a shooter -- but not monetary value, you'll understand.) Likely from Germany, possibly from the same time period as your other Germans. The solid reddish marble also has quite a few hits. I thought it looked like glass but with it surviving that many hits maybe I'm wrong about that. The rest of the marbles are called slags . At least one is what is called "handgathered", where someone dipped the glass out of a pot on a punty and then snipped it off and sent it down the mechanized rollers. The slags are from the around 1903 to around 1930. During this time the marble-making process switched from handgathering to a more fully-automated gob-feeding method. These are made in America.

#2 Peltier Rainbo #3 ... that underwater view is interesting. I was thinking Akro until I saw that. That put Master in the mix for me, but I have to admit I haven't seen a lot of Akros from that point of view #4 I think that's a Vitro. The kind sometimes called Transparent Whitie. In the Tiger Eye family. WV swirl on left and right

Nice. I am also unfamiliar with the Sunset name for MKs. Is that pale yellow on the top one. Laughing at myself for focusing on the simplest one ... but bees and bee-like marbles are special to me.

Master did black bananas. There are also some Asian ones which sometimes find their way into banana photos.

Jason? @bumblebee

How weird. p.s., you have an eagle eye to see that little birdie in time to catch a picture.
