  Do the non-opaque Cairo marbles have kind of a unique feel?

Each company had its own particular structure / motif in the construction of marbles, although they could be very similar to each other, such as Heaton and Cairo

Some reasons may be distinguishable for a particular company, so what is certain, others (in the case of the third and fourth photos above) are just feelings that you can have

Sensations, for the structure of the swirl and in the way it swirls, already seen in that particular company but, without being completely sure

I'm down for Ravenswood. The glass is too nice for Cairo IMO but I see why it was suggested. Also I see the purple in it and the metallic bit at the seam.

Is that deep purple a Ravenswood trait!?! I have a few that are a very unique royal purple clear. Thank you!

Yeah, I'd call that Ravenswood. 

I think you are right. Would love to find another example of that shade of blue glass though. To me its a pretty unique blue. Thanks all for helping figure this out!

These companies made marbles 24hrs a day, 7 days a week, 200-250 per minute, sometimes for months.  What is a run ?   They might change colors ten times a day or once every two or three days.  The worst thing for a glass furnace or marble machine is to shut it down and let it sit. The machine rolls will begin to rust in 12-24 hrs. Big temperature changes will cause furnace brick to crack. The term RUN is misused very often. This started after the investor runs at Jabo in 2008. They were specific numbers of pounds of glass paid for by investors. They usually lasted 8 to 12 hours long and 2000lbs. Once that specific run was done the furnace and machine was never shut down. We just rolled out the 3/4 machine and put a 9/16 or 5/8 back under the furnace and went back to making industrial marbles. Vintage WV swirls companies might make 2000 or 6000lbs. of white base and blue swirls. Then make 2000 or 6000lbs. of white base and red marbles. Then maybe make 2000 or 5000lbs. of white base and orange swirl marbles .  What ever they needed or had orders for. Once they were all made then they would be mixed together packaged, bags, boxes, drums, etc and shipped.   Many of the multi color marbles comes when the color changes happen. Making white base and blue swirls. Switch to red. Let the blue colored glass run low and get thin. Add the red on top of the blue. Now you have white base with blue and red swirls. When the blue is totally gone you have white base and red swirls.  So what is a RUN ?   Where does a run begin and stop ? That will probably be different with many people. How do you know when the changes happened unless you were there ?  Unless you were there or someone was who knows when something started or ended. How do you know when a run began and stopped ?  Very hard if at all possible to know what a run was unless you or someone witnessed it. So many terms misused with marble collecting. Like cold roll mark.  One hundred more times likely to be a hot roll mark rather than cold roll mark. But once it is printed in books, it is almost impossible to change. The answer is always, but it has always been this. To move forward requires change.

This explains a lot--The difference in Akro corks for instance- the fire/furnace was always going and the glass colors continued to change.
They keep it going to keep it going—production was the word.
Love it Ron--good explanation.

The number one key with every company was marbles per minute, per month.  Everything else came in line after marbles per minute, 24hrs a day.  Correct once things were running standard product, keep it running at all cost. Making any repairs and adjustments at all possible, on the fly while keeping things hot and flowing.  They never shut down and everybody went home at 5pm each day.  At the most worth a penny each and at 200 per minute, they might make 200 cents a minute before any cost were deducted. Deduct the natural gas, the equipment cost and maintenance, the ingredients, labor, advertisement, shipping, etc. The 200 cents per minute gets small.  So every minute counted if there was to be any profit. Keep it going, to keep going, and have a job. One of the lowest paying jobs at the time,
