Absolutely Vitro.

More pics please. Try to show us the ends of the ribbons. Not a lot of sun shining through.

no idea

Ouch!

Until further photos change my mind, I'm going with Vitro cats eyes.

Following. Not familiar enough with the blended MKs. Is this something you've seen before at the 3/4" size?

I understand. It's awkward for me. I have to convert take the extra step of converting it to fractions. But I cope.

My first thought is WV swirl on this one.

There's some fire there. Could be Pelt Acme Realer, or some kind of opal Vitro. Some of the views seem to have a Pelt-like grain. Okay, now I'm "leaning Pelt but". I do not know. (obviously)

What does it look like backlit? Any fire inside?

Now it's all blurry in my brain. I guess Vitro is a possibility.

I was about to say Akro. I'm still saying Akro. But you really made me stop to think when you said ppp ... made me wonder about acme realer.

Agree with whispler

Georgeous. 1978?! How wonderful you could turn this whimsical art into a lifetime. Welcome!

Yes, Anacortes sounds right.

Especially pretty

The top is for sure an Akro. I don't know any name for it though. I believe the second to also be an Akro, again with no name that I know. The last marble looks Master. I also expect that many would call that one a Sunburst. I don't call it that, but I understand the custom. (I just call them Master because by the end of the 1930's, the Master production didn't really match the catalog descriptions for the names they introduced in 1930. But in a world which needs names, I can't complain when people try to fit them into the pigeonhole they think comes closest. And Master kept using the names but I don't think even they cared what went in which box in later years.)

Yes, these are the newer, made from the late 30's to the 60's (not certain of last decade). These are Rainbos. The NLRs -- National Line Rainbos -- were from the late 20's to mid 30's. Your particular Rainbos are are called Sunsets. At least the second one is.

Here is a 3-way Japanese cross-through Murray Long posted. Here are some of my Americans. Some have cleaner cross-throughs than others. I don't know if the 4-color one is considered a cross-through. I suppose the top left wouldn't either. But I still wanted it for my St Marys group shot.

I am not certain who made it, but I am leaning American. Not what we call a cross-through. "Cross-throughs" have two or more distinct colors. The "cross through" part is about how the colors are arranged.

Believe it or not, when Akro sold them Akro called them Moss Agates.

The lavendar based ones were made by Jabo, sometime between 1991 and 2007.

That's a far reaching blacklight. What do you use?

Chalindaville!

Without packaging or other provenance it can be difficult to tell which decade the cage-style cats came from. The Parkersburg location was making cage style cats from the 1960s to 1989. Anacortes only had a small time to operate -- 1989 to 1992. So odds are Parkersburg for most loose cages. There's something romantic about the name Anacortes, isn't there. We want marbles to be that even though that actually means they're more modern. ( :
