There is a guy selling marbles as chalkies on ebay. He's been coming up with loads of them. He says he's digging them up out west somewhere with a mixture of all sorts of makers and styles. Many have white glass sickness from some sort of corrosive condition either from the ground or from something they're being soaked in. He's been told they aren't chalkies but that doesn't stop him. It's all about the money.
I don't know, I'd pass on that marble even if it was free, without the junk in it, but with the junk I'd give a buck for it. Just because it's different.
They are "impossible" to ID until you've looked at and handled literally millions from various locations, and then they suddenly become only "nearly impossible" to ID.
This one is Ravenswood.
Size (many RWs are smaller than 5/8" but the late transparent swirls are commonly over)... fits the type. Bubbles fits. Peachy champagne base glass fits. Fleshy tone to the ribbon fits. Pattern fits. Coppery colored splotch marks in pic 4 seals the deal.
I hear ya and agree. They made the Paul Bunyans, and these types seen in bags for Alox and another company which escapes me at the moment, big clearies, and occasionally I run across a pretty big sunburst. But I'd say the big ones are more common with Master than the small ones (peewees).
Agreed, Vitro conqueror. They can be tinted base or not. Amber, blue, green, brown, maybe others but those are the usual tints found in conqueror base glass.
