That's tricky. Looks almost solid color. The dents are like the cold rolls on your black and white swirl. Marble wasn't quite hot enough to get fully rounded when it went down the rollers. I don't have a guess on maker.

Does it have an iridescent finish? If so then maybe Vacor Starfish. https://www.billes-en-tete.com/detail.php?id=247

(But for the record, what Vacor called a Confetti is more of a cat's eye. They had different names for their frit marbles.) https://www.billes-en-tete.com/detail.php?id=71

With the multi-color speckles on white, I am going to guess Asian. But I won't swear it's not Vacor. Definitely "foreign".

Hi Edward, welcome. Single colored marbles are tough. But I think I might be seeing signs of the marbles being modern and Asian. (Tiny little u-shaped or v-shaped cutlines on the poles can be a sign of modern, Asian.)

No "pontil". Pontils are on handmade marbles (or at least handgathered ones). This marble is completely handmade. The crease is a "cold roll". From where the glass was just a little bit too cool to be completely rounded as the marble went down the rollers. It might be a Vacor Zebra. https://www.billes-en-tete.com/detail.php?id=70

If we're sure those are machine-rounded, I wouldn't think so. But

There is a 1973 book called A History of Glass in Japan, by Dorothy Blair, which briefly mentions marbles. I saw it in a "snippet" view on Google Books. I didn't see the years but was after "when electricity came into use".

I found the article with the offensive language. Be warned, it's bad. It is the April 15, 1907 issue of The Mixer and Server. The relevant quote from near the end of the article is, "Japanese glass marbles of much beauty sell for a cent apiece, . . . " https://books.google.com/books?id=25GfAAAAMAAJ&pg=RA3-PA3

It's truly blue in hand. If there's a second color it would be white. I guess I better work on taking better pictures.

I got some decent pictures of some glowing Marble Kings. Thought I'd share. Feel free to add. Well, fairly decent. These looked blue in my photo viewer on my computer, but they're coming across as purple to me on the screen now. Anyway, it's blue in person. Pretty sure they're modern. Would be sweet if it really was purple, eh? Here's the ordinary light photo, with all the blues. Most didn't glow.

Sorry! You're right! I'm wrong! I'm naughty. The best clairvoyants will just call you to make an appointment, and since they know they're such high demand, they will have staff to call the people they can't see, so that the people they can't see won't languish in doubt and can go seek help in other venues! Right?

If I ever get caught at a karaoke joint and put on the spot, I'll say yes! This will be my song.

cool

Hi Jane. Nice mib! I see your dilemma. I'll vote Alley. I"m not certain but since the flames seem a little faded on the edge and the green doesn't look entirely solid, that makes me lean away from CAC. Hopefully someone else will weigh in.

That piece has a lot of history ... which I just learned some of.

That was my best guess. I think it got eaten. But surely others survived. I saw quite a few butterflies this summer.

Alley seems a good guess.

Bottom left at least looks like a Vitro Tiger Eye. I guess all Vitro. Maybe all Tiger Eye but someone else might see a different style.

Do we have any people here who can read Japanese? Well enough to dig into history? What kind of marble historical facts would you be able to dig up on Japanese Google? I have seen an explicit reference to very early Japanese marble making, but it was said in a mean way so it's not something I have kept in an easy to find place. I would LOVE to learn more about Japanese marble making in early 1900's, but how?
