The opalescent "fire" (glow) may be there but I am not really seeing it in these pics. Do you see "fish eyes" (a little clear spot/window at opposite poles) on any of these? You may want to check out the nice post Art made about Flinties not too long ago . . .

You might be right, they sure did make similar ones, but I think the "shadow effect" at the one seam is way more common on Vitros than MKs, which is why I went that direction.

All I will add is that it seems to me, if someone was attempting to deceive, matching colors would likely be the easiest part.

I do not have any of these but they are very interesting. I agree that the colors look identical to the "PA Dutch" but all of those I have seen are much larger, like the one you show. Have you seen "PA Dutch" marbles in this size that are the quality of the large one you're showing? And is the difference in the bodies of the small ones and the large one as apparent in hand as it seems in your photo?

It's a Vitro.

Yes, lined crockery - I think some folks would also call them "Jaspers".

It's fun to collect variants of different sizes.

Big and clean too - nice one, Chad!

Another great set this week. It's been a real treat to see your collection. Thanks for showing them!

It's one of my favorites from Sistersville, made during the time Christensen was operating in Cambridge - seems like Lawrence Alley was determined to give them a run for their money.

I'll add one more for today . . .

Good to see you back, Tommy. You posted a bunch of good ones today - this one is my favorite, and I really like that blue and oxblood too!

Nice mibs, Dave. I especially like the nice transparent glass on this one!

No kidding, Chuck - I completely agree. You scored a bunch a nice ones but this one is off the hook! I've never seen that sort of mottling in green before.

Happy WV Wednesday!

Joe, your photos are really great and the marbles are nice too!

They're all nice marbles, Marboman, but I especially like the base on the first one.

My first take is Akro. Is the base opaque?

@Dave 13 I set these on a piece of tinfoil to make the "fire" a little easier to see.

I thought the same thing but can't imagine where the other two ribbons would be - seems like we'd at least see four on the side showing and I only see three.

It looks like a modern Cat's Eye to me.
