I'll start by noting that paperweight technique (aka "lampworking") goes back several centuries when beadmaking started. Complex paperweight worked started (IIRC) around 1880 using gas and a mouth blowpipe to increase heat. Paperweights appeared in the mid-1800s in Venice, and later in France. Complex designs with very fine craftsmanship appeared in the late 1880s IIRC. The techniques progressed and some studios turned out incredibly finely detailed work with relatively simple torches. Paperweight were originally simple glass half-spheres meant to hold down papers in rooms with windows open. These evolved into decorative art for the home. Their form could be half-spheres, spheres with flattened bottoms (cold work), animals (I owned a Hedgehog) etc. Almost any three dimensional that could be imagined could be made - depending on the skill of the artist and the time that had to make it. Today there are artists like Paul Stankard that create work that is so detailed that its is quite a sight to behold in person. Even photos of his work are striking:

The only way to make a glass piece with that detail is a torch paperweight technique. All cane attachment points can be cold-worked (polished) away. Cane-cut marbles are an entirely different method than paperweight technique.

Its a machine made.

Baller box!

The reaction appears to be blue.

I have a few - and I'm interested.

Maybe its because the pics are out-of-focus and the coloration seems odd, but I'm not 100% sure that its Akro.

Its in pretty good shape. I recommend against any treatment.

At one time, Bill Cokenhauer had two for sale at Ohio and other shows. I think they sold after quite a while and later Bill had a third one. IMO they are far more paperweights than they are marbles. Kids marbles aren't made in such large sizes. The technique is also paperweight.

What color does the ribbon appear to be in-person?

A name invented by sellers to fleece buyers for more cash.

Crockery type.

I'm a bit intrigued by the blue/black strand at 3:00.

Pics are needed.

Contaminant from the gather.

As noted - Pelt.

Those would be odd colors for Akro.

All German. The 3rd one is coreless. The 5th and 6th ones are divided ribbons. The rest are Lats.

If they are at the surface only - it would be crud on the rollers.

Not oxblood.

It is a funnel. Look at the glass to tell you what was being made at the time it was retired. I have two Akro Agate funnels: The first has translucent olive green glass with oxblood. The second has a little bit of everything stuck to the top, including a marble. The clear glass is a bit visually interesting because of the ghostly blue that is wafting through it.
