Those are nice ones to have, Art!

I have always liked those Presidential Sets - such a great item. Did Nola get to keep that marble she made? That would be a pretty special marble!

Oxblood is oxblood, as you say, even though there may be a few variants. All the rest, Blueblood, Blue Eggyolk Oxblood, Blue Oxblood, etc., are just names of a particular type of marble that has oxblood on it. Having said that, I have seen people use some pretty creative terms for marketing purposes - usually in an effort to call something that is not oxblood, oxblood. lol

Way to start the day, Dave! Lady Tater

Now that I think about it, Chad's marble is the Blue Oxblood, the one I posted (and @I'llhavethat1 is talking about, I think) is called a Blueblood - sorry for the confusion!

And marbles like this one that Chad posted are also called "Blue Oxbloods"

The ones I have and have seen have the oxblood under blue. If it was on top of the blue, I don't think it would be so hard to see.

Here is a Blueblood . . . The oxblood is under blue and if you don't light it up good and look look closely it can look like a dark blue corkscrew.

I think Cairo too. "Vitro" is the Latin word for "glass".

Beautiful groups, Alan!

There's sure no "sorry" necessary, Bill, I was just goofin' with you. ☺️

Me too.

Even cooler than it was 12 hours ago? 😉 😊 Although, I do agree - it's a very cool mib!

Nice score, Tommy!

Looks like it has some Vitrolite cullet in it - does it glow under UV? And what size is it?

Pete retired.

Too messed up for me to guess a maker, at least for me.

It's very crude, pretty much useless for marble games. Maybe it was made for decorative or industrial purposes - like for a lamp pull or claw foot or something.

The top one's sweet for sure, Bill. But I really like the orange peel on those big ones!

My best guesses on these would be Champion (maybe Alley), Heaton (maybe Cairo), and a JABO Jorkscrew.

It's a simple fact . . . not all marbles can be positively identified, and transparent swirls are notoriously difficult since many companies made very similar marbles. I like the sort of "chevron" patterns on this one - it does look like it got spun on the rollers, whatever it is.

I think Heaton is a very good possibility.

You are really fortunate to have that marble and the letter from your Grandpa. The set is a heirloom for sure. If it were mine, I would do my best to see that it stayed in the family.

Definitely Vacor, and there are plenty of them around, as far as I know - probably not as many as the smaller sizes though.

Not to say it isn't often cool, but I think horsehair can be just a streak of some contaminant in the glass stream, and that it's usually unintentional. And I'm thinking maybe Heaton for Rick's marble.
