Naked Core Vs Divided Core

[marblerob]

Its the newbie again..I have been reading some of the literature but cannot figure what is meant by "naked core' or "divided core". Are both "ribbon marbles?"

[lstmmrbls]

No. Naked core means nothing in the center of the marble.

[ziggyzora]

To me a naked core is a single ribbon with no outer bands. A divided core has a central ribbon divided into 2 or more parts and may or may not have outer bands. I could take some pics if you like but chances are someone else has some ready.

Galen, did you mix up "naked core" and "coreless"? When I first saw the question I was thinking the same as you but now that ZZ has posted I'm like "oh right!"

In Collecting Antique Marbles, Baumann allows for ribbon marbles to have either one or two ribbons. (He says it's debatable with 2 ribbons would count as a double ribbon or a divided core.)

He also seems to apply the term "naked" only to the ribbon style marble - when there are no outer bands, like ZZ says. (So then would Baumann apply the word naked to a double ribbon?)

And then the divided core has more parts inside. Baumann says the production style of the divided core is similar to that of the ribbon core. But a divided core is still considered a different type from a ribbon core.

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.

It appears I was wrong. It will happen again(LOL)

well usely the word naked is used more with the term of the outer lines of a hand made naked core marbles would be like banded ,onions Joseph coats . any thing with out any decorations in the center . like most Lutz . and as far as a divided core it is just like it says . so when talking naked it is both inner or outer and as far as ribbon marbles yes divided core would be ribbons Mike well after looking at the marbles I need to clean as the dust gets sticky

Here is one of those

Just a thought.... a double ribbon is 2 ribbons with a different configuration/colorway going on in each (like the one posted above) and a divided core is 2 or more ribbons but the same configuration/colorway in each.

[I'llhavethat1]

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

I agree with ZZ. This marble is a classic double ribbon core.

The only instance when I would term a core with two bands as a Divided Core is when the two bands are pretty much on one side of the marble and there is an obvious space where the third would have been. If the marble has two bands in th core that are pretty much opposite each other, I would categorize it as a double ribbon even if the bands are the same color.

Me too. Bauman essentially says "Single ribbon core," "double ribbon core," and three and more ribbons = divided core.

Naked = no outer bands, regardless of what's happening in the center. Not confined to ribbons . . .

"Naked core" could be anything -- just means that whatever the core is (latticinio, ribbon, solid, divided, etc.) it has no outer bands.

edit

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

Nice ones!
