The density calculations are a good start. Still relatively light at 1.4. Some type of polymer is my guess but I haven't seen one. Is it really a paint coating? To get that pattern, the construction (how the surface bonds to the core) might tell more about the material than the density. Paint doesn't stick too well to some polymers.

Those prices are probably 40 years old. Just goes to show things change, I'd think a parrot would get a better price than a donkey nowadays.

There's a price guide in this old book. donkey and bird both listed. If only! lol

I've only seen the term applied to a Peltier, if it has a translucent blue base and orange-y yellow ribbons like some examples shown in this thread. Backlight the one in question from the first post and tell us what you see (getting a back-lit pic can be tough).

Nice marbles , one of my favorite patterns too. you should let them out more often...

Dan, glad to see you lol -ing. I think you've got some decent marbles there. If you can work a scanner, it's pretty close , but your latest pics are looking OK!

Would you entertain a digital camera in trade for some of the marbles posted?

...of the first two marbles posted, I meant. lol. Regardless, marbles posted in your second group look pretty much hand gathered to me too, you obviously know what a pontil looks like, right?

I'd venture hand gathered on the second marble re: bottom row middle. Maybe on both actually. Nice marbles.

Which pic has the cut/shear mark on the second marble? Is it that circular mark on the bottom left pic??

Some of my favs.

Alan, that's the type of controlled pattern I mean. Is it a trade secret or how exactly does the bubble make a non-bubble shape. Almost looks like a "sprue" on the B. Those are awesome marbles by the way.

A lot of German handmade marbles had air bubbles in them too, usually following the path of the pattern. I'm curious about some of the contemporary air inclusions in the form of a ring. I wonder how those get made. Same with the birdcage marbles.

Is there any transparency to the green glass? Hard to tell from the pics if the lighter/darker areas in the green are from "depth".

Hi Chuck, interesting marble

And another three. 3 best x 3 rarest = 9 bestest so I figured I might get away with 9 total mibs. lol. I make up my own math sometimes

And another three

I can't say these are my best or rarest three, but they're some of my favorites

At a glance I wondered how much of that article would even be considered accurate. Does "Semi-mechanical" on the German handmades account for a grinding wheel??

Was there a Blue Latt in this auction somewhere?

Probably had a lot to do with the industrial revolution. Things made leaps and bounds back then, machining etc. Augers have been around a bit longer

A jar of Citrus-es (or even exotics) sounds good to me. Big ol' jarful of marbles. yum

I don't know the specific topography of the area or what archives would show, but I know of a bunch of smokestacks that used to be around, at factories, that aren't there any more. Same with the factories. I don't mean in Europe, I'm just talking generally. Back in the old days there were a lot of factories that burned down and chimneys that eventually had to be demolished since they became a safety hazard. Interesting marble topic/discussion

Cool! The smaller mib with the bag is even cooler
