That's a good Champ size.

No kidding! Some folks have dedicated marble rooms. Maybe I can at least set up a nook when we move. Priorities, eh?

Ooooooh! I'm going with European Sparkler for that. Assuming it's vintage. If it's modern, I'm not familiar with who could have made it. And oooooh again! Nice pairing with the big and the little.

This one is blurry small size ... so I'll definitely just link it to YouTube where you can see it littler than here https://www.youtube.com/watch?v=MBy83LjbqzY (Make Room for Granddaddy -- with Frank Sinatra)

That is gorgeous. Ohmigosh, that must blaze under blacklight. Beautiful in any light.

Alley I'm 99.99% on that.

What size? If in the standard playing size, then good chance of Champion.

I'm pretty sure I know the answer to that one -- from memory -- but now I have to go back and remind myself the logic of why it works. It's a good 'un. Edit: yup! I got it. It's just a little bit slippery. I needed a diagram.

Not a sparkler. Not sure it's Akro. The colors look Akro but the structure looks a little Master-ish in that view. For comparison, here are some Sparklers which Alan posted.

Maybe Peltier Peerless Patches. Other views could change my mind, but you do have a number of PPP's. So it fits.

I really do love that kind of riddle. It's close to a kind of riddle that my brother introduced me for killing time on a trip down to Mexico. Where someone poses a simple-sounding situation and then you ask lots and lots of yes-or-no questions to try to figure out what the real story is. This type ... http://www.destination-innovation.com/articles/the-top-ten-lateral-thinking-puzzles/

This is an art use ... but with the marbles being a tool in the art, not a final part of it. Okay ... steelies ... you may not call them marbles. But wow. "In a 21st century take on the traditional Zen sand garden, artist Bruce Shapiro invented the Sisyphus Machine, an elaborate kinetic drawing machine that uses magnets to drag rolling steel marbles through a thin layer of sand to create complicated mandala-like patterns." Bruce Shapiro’s Mesmerizing Kinetic Sand Drawing Machines

Some subtle, ingenious, mesmerizing stuff happening here.

So much history to be learned while pondering these little bits of glass. (I also learned quite a bit about European economics in the 1800's just in the course of studying marbles.) (Some of that history may have influenced my ancestors' migration to Wisconsin a century and a half ago.)

Not seeing any oxblood. When I think of white-based Heatons, I think of a softer, more translucent -- less expensive -- looking base. The softest, most nearly translucent base that I see in Shell's photo is probably the front right but those ribbons are well-defined -- much sharper than I associate with Heaton. Heatons may have had a range -- at least one of the bags in the link posted below have fairly well-defined ribbons -- but my general feeling is that Shell's still fall outside of the Heaton range ... not to mention that Heaton was a smallish company founded in 1946 -- which is after the period that I think the main portion of Shell's collection was assembled. http://marbleconnection.com/topic/6790-mostly-pix-heaton

Nice name (I also liked your "Earths" ) So, it's a West Virginia swirl. My first guess is Alley, but without confirmation, I'd leave it in with the other Transparent Swirls.

Aw, sad but sweet example.

Love the bright shade of green. Not all that easy to come by the bright ones.

I could see it being Master too.

What kinds of things have marbles been hidden inside? ... commercially speaking ... I was remembering Fuzzy Wuzzy soap and the toys inside from when I was a kid ... don't know if they ever were marbles. Fuzzy had toys, right? Tried to google for reminders and found this! Surprises inside soap endure! Source: https://www.facebook.com/Soap-Company-412650728929917 And I remember some examples with marbles sewn into old toys to help them hold their shape or provide weight ... and no one was ever supposed to see 'em. Need to look for those.

It's the white which almost seems to have been painted on the surface. (Edit: Richard mentioned coloured glass without specifying white -- and now I'm not sure why I said "white" without thinking of other colors -- need to hear from others.) Yes, Conquerors are sometimes thought of as brushed patches -- though since they have another name I sometimes forget they're described like that. Some Masters are called brushed patches. This one from MarbleAlan's site is a classic example. Of course it's not really "brushed". The molten white glass would be injected somehow into the side of the other streams of molten glass. How they kept it all where it was supposed to be, I don't know.

Red on white is especially hard because it was a popular combination. (I think "yes", all or most all did single color on white.) Some people might be able to tell from the base glass if it belongs in say the Christensen Agate column or the Alley column or the Ravenswood column. Some people might be able to differentiate between the shades. I don't remember if I noticed any "pink" yesterday, but maybe someone else would see that as a significant shade. I'm not seeing Champion as a strong likelihood here because the base glass is so nice and the ribbons are so sharp. I don't know that that 100% rules out Champ ... but it's why I'm leaning toward possibly those being a combination of Alley, Ravenswood and Christensen.

OMG. OMG. OMG. yeah! The black aventurine is a really really good thing! Is it a Peltier Peerless Patch? Hopefully someone else will weigh in on this one. Nice!

Hmmmm .... Not sure. Not sure if it's the lighting which is making me unsure, or if I'd be uncertain about the pattern anyway. The white looks a little frosty from here ... a little thick ... in a way which makes me think of "foreign". But old foreign or newer? Can't tell if the seam is long-ish or short-ish ... or is it medium?
