Amber Slags?

[COVRSWAP]

Hey all, are these amber slags? New or old? 0.93 inch / 23.6mm in diameter.

They would be considered as slags( amber--nice dark amber)-One base color--transparent amber and white included.

I believe that these may be from the good ole UK.

Nice marbles!!

A great share--keep them coming.

Marble--On!!

"even though . . ."? I think they are very nice marbles, period. And my guess as to their origin would be the Netherlands, Japan or Germany, in that order.

@COVRSWAP The term "slag" is an old one. A slag is any marble that is composed of only a transparent clear or colored base glass and white striping glass. Your marbles certainly fit that definition. But some marbles that have the same composition are called "swirls", based primarily on the way the white is distributed in and on the base glass (please don't ask me to explain the differences, it's just something you sort of figure out, eventually. Maybe @akroorka will take a stab at it. 😁).

I think many people, me included, would call your marbles swirls, and as @Fire1981 said, they might be wire pulls. Wire pulls are a particular type of swirl where there is only one continuous stream of striping glass. If you can only find two distinct ends on the white striping in your marbles, they are indeed wire pulls.

Here is a fun exercise . . . Imagine that the amber base glass of your marbles is opaque white and the white striping glass is opaque red. The only red you would see is where the white is currently on the surface. Those marbles would be called swirls, with no possibility of being slags. 🙂

I only insinuate that there isn't as many collectible foreign marbles as their are American marbles for machine mades that is

@Ric Many thanks for the detailed response. Mind blown 😂. Clearly a long learning journey ahead. Thanks for the advice and guidance.

Thanks @Ric, (I think—I just went on a torrent--oh well this is just me)
 A slag is a single stream marble meaning there was one stream of glass, one white and one transparent coming out of the Kiln/Machine to complete a glob of glass that was transformed into the cute little orb😁 that we all enjoy today. 
In the older slags this meant one pot containing two colors—one white, one transparent color. They were both mixed (no double dipping here—lol). 
Glasses do not mix color wise—they just get along with each other sometimes. (Many times, it does not get along and that is why we see so many “experimental” types that were dug. Some are very cool to collect but never meant for general sales)
The “Wire Pulls” are a different animal and I truly believe that they had an injection process that revealed the one continuous line that formed the “Wire Pull”, so two tanks in a two-colored marble.
This could not have been achieved in any furnace without the addition of another tank of glass feeding the final marble imho.

The Kiln was the machine, not the rollers or the cut knives. It was stationary and operated with gravity and intense heat. 
Generally, the “machine” in the Machine-made world had multiple colors involved—all from the same heat source and this is where it becomes complicated.
I look Forward to @Alan chiming in here, he has a wealth of knowledge.
Marble—On!!

I'd say that structure looks like veiligglas to me...
