I cannot agree more. I own a few pieces that 95% of people would look at, blink once and not grasp the import of. And that's fine.

Those are great colors. That's been stored out of sunlight for much of it's life. Its in great condition too.

As far as objects - I have a nicely used Akro funnel, a few plungers and two spinner cups. I like them because I'm focused on production methods.

These two:

Looks like new torch work.

No MK hallmarks for me. Foreign a real possibility.

Most silver and milky oxbloods hover around +_5/8". There are plenty of the veneer types (often with red on white bases) that approach 1" dia. There is a unusual oxblood on a opaque/translucent base type that 99% of people have never seen. Roger dug them in his early dig days. I have seen three, own 2. One is 1-1/32 and the second is 1-9/32. In both the oxblood is primarily subsurface, rising to the surface in bands. Unusual and old looking.

I suggest thinking of it in terms of a small "glass trades village". Sources of circa late 1800s materials and chemicals would be limited and well-known within very low cost limitations. Techniques are known and shared in the small craft community. There were no secrets. Each shop could simply duplicate anything seen with no real effort. That leads to fairly homogeneous products.

I wouldn't do it - but thats just me. If you want to spend money and time on a basket case - get it polished. YMMV

If you are referring to cane-cut handmades, my understanding is that they were made in shops primarily concentrated in glass-making towns such as Lauscha. Glasfabrik Wernerhutte was a large facility, but its important to understand that marbles were just a fraction of their output. Scientific glass, decorations etc were the primary output.

No.

Top one looks like a swirl. None appear to be UV reactive from those pics (although UV reactive doesn't mean anything).

The "Ak" in Akro is pronounced the same as the "Ak" in Akron, Ohio.

If it helps - you can use the Ravenswood thread that I created long ago on MC.

As if Scott ever cared about marbles or marble collectors.

I'll note that these days I'm seeing a LOT of people putting UV light on everything thinking that its some kind of Magic ID proof of something - and mistaking 'REFLECTED' UV light for 'reactive' glass. Most don't want to be told that they are mistaken.

As noted - not oxblood. FYI - oxblood isn't transparent. Try not to "hope" for oxblood and it will be easier to accurately identify.

Scott Patrick had a well-known period of creating fake marble tournament medals.

Take care not to temperature shock that piece.

Left and center probably Jody Fine - but I should note that I'm not well-experienced in his work and he has produced over a long number of years and there is a lot of diversity in his work. I can't hazard a guess on the right - but the control shown is from an experienced artist (like Fine). Some day I hope to own one of Jody Fine slices of Marble Pie. I've never seen one for sale.

Not enough resolution, focus or closeness to the marble(s).

The photos are not focused enough, close enough or lit enough to judge.
