ooch those are nice looking marbles

yes

Pontil pic in post 4 looks interesting..

Those onionskin examples show lobes pretty well and yes certain solid cores are also good examples of the pattern. usually with a contrasting colored "ridge" on a white or yellow lobed core. edit (some divided core swirls can have what look like lobes as well, most of these are solid cores with 3-4 lobes. note: the outer layer of fine yellow or white "strands" are what makes them non-"naked" examples.)

edit The one in the middle is a naked solid core since there are no outer bands or layers.

Sometimes (most times) a really clear glass in a handmade marble makes it more collectible but there are some really bubbly ones people like as well so no I wouldn't say it's a flaw unless trapping air or having the glass too hot is considered a bad thing. A few contemporary Artists purposely trap air in a marble

That red one is pretty cool, last view reminds me of Jupiter. Sorry no help with the VM

Any pontil pics? Building a home with a bunch of display cases sound like motivation to me! lol

You lost me on the configuration/colorway. Does that make it a divided core or double ribbon by that logic? Either way it's good example of a non-"naked" marble due to the outer yellow bands

Naked core to me means no outer bands/layers or decorations, just whatever's going on in the middle. Like a solid core with no outer bands, or a ribbon core with no outer bands, etc.

Oooo I see a couple I like too, nice group. On ones like Post #12, that sort of pattern could be from near end of cane if not end of cane (or beginning of cane depending how you look at it). Is there a pontil on the end where the pattern is unfinished? The wild one in the first close up looks like the cane started to deform and was rolled over on itself. It probably started off as a latt core with colored outer bands. Don't see that pattern too often but IMO they are some of the grooviest looking marbles.

I didn't find them but found this pic I took earlier, I think the blue might be close (yours obviously has a lot less opaque white.

Hard to say Winnie. The glass on your marble is very clear and also striking color and pattern. I packed away a couple like this the other day I'll see if I can dig them out for another look. I see what you might be seeing as well, some Peltier marbles do have patterns that look similar. If you have this in hand maybe you could describe what's shown dead center 1st view and 5 o'clock, on the view to it's right. Is it a fold of glass, or...?

nice perspective

That's the pattern, Ric

Can you imagine showing up on the playground with that bad boy the size of a baseball? "largest vintage marble known to exist" man, it's a work of art

I don't think that's a pelt, slag or AA. Post #1 looks like it could be a wild Pelt pattern but the other views make it look more like a swirl with transparent areas. Like champion maybe? Or maybe I'm seeing it wrong. lol nice pattern though.

Almost 2" is about as big as they'd probably be able to make for a good seat on a check valve.

cool marbles!

A lot has to do with pattern and color so it really depends. Over 1-3/16" with a decent pattern would be of interest...majority of large slags I've seen are that size or smaller. Of course there are bigger slags out there... The whole industrial application is an interesting topic. Industry usually tries to save money by doing without excess so I'd expect the ones made for industrial applications to be made from the plainest glass possible (ie: those transparent green marbles used for fiberglass or something) Back in the day where things were at the onset of industrial revolution it would make sense that large slags would be used for industrial applications, cause hey - they're already in the business of making marbles and if there's an order to fill for some larger marbles other than "toys", why not?

These new silhouette avatars after the board update add to the "all I could see was the outline" mystery

looks to work ok as far as I can tell, and I love looking at this pic so I'm glad.

The sun shining through those marbles would look amazing I bet, very cool
