Leaning Alley.

The vacors will have two yellow patches and some faded looking edges of the patches where the glass thinned out over the base.

I agree with Pelt. As far as I know there were no Canadian glass marble companies.

The only remaining intact WVS tank outlet known. Heaton Agate, with streaks of oxblood in transparent green and a white ribbon and the piece of white vitrolite still melted in place on the ledge over the orifice for the striking glass.

Champion.

St Marys Alley. White ribbons in another base color? Sure, millions of them.

Alley Inky

The term tankwash was when the tank had one type of glass in it (say for industrial marbles), and you are about to run and investor run of a different type of glass with a different coefficient. So you flush (wash) the old out and run compatible glass so that when you start adding the base and striking colors, you aren't contaminating the marbles with the incompatible industrial glass. Mostly it was a term invented by workers at JABO and I'll just say it was an abused term. That's how it was explained to me by more than one involved at JABO anyway. I agree it's Champion.

Looks like one to me.

Fine #0000 steel wool is how I remove these rust marks. I think the marble is Alley. Similar to a certain Heaton type but busier IMO. It's not going to hurt the glass, it's a tool even professional window cleaners use.

Odd one

That's a Cairo swirl.

Wow, that's cool!

Well it helped that they were in a big lot that contained what appeared to be the contents of a vitro bullseye bag. I picked out several mint bullseyes and probably left a few but couldn't leave these. Always on the lookout for different color combos.

Transparent swirls are pretty tough unless they show some good traits. If I was betting I guess I'd go with Heaton.

Top left looks tan base, bottom right is electric yellow and the ones between progress. Which is more accurate?

I lean Alley. Just not much action in this one.

Found with Tiger Eyes.

Here are a couple cool Vits.

What size is that smaller Neon Conqueror Melissa? Rare find! Thanks for sharing.

Champion is a good place to keep it IMO.

Asian.

Looks like early Alley.
