Not seeing peltier on this one.

The photographs are awesome. Thank you for sharing. Akro also used Miller automatic shears, and nearly a decade before Peltier. Akro purchased 3 by 1915 according to a National Glass Budget 1915 periodical.

Winnie, the cut-line is not always visible on akro slags. I've found that the cut-line can land on the transparent part of the glass and not on the white. Making it extremely difficult to find. Especially on slags with little to no surface white.

I agree, last one is pelt. Nice fold.

I think i've just been "Mibstified". The yellow & blue is one sweet looking peltier. Last photo in the center, i see an akro with submerged oxblood, very nice. The marble in my post i have with my Akros, but let me know if you see something else. ...........after all folks, it is a chameleon.

1 more vote for master.

Aren't more of the early swirls opaque, and not so many transparent? And that may be why the majority of transparent swirls have less of a quality look to the glass than slags?

I agree, probably not designed to that much of a degree. But, shears are adjustable and there are some noticeable differences between certain companies. Come back out Mon.... Ann, the other difference i see is slags have a different look or quality to the base glass vs. WV swirls. Could the difference be batch glass?

I absolutely agree.

I agree, that's why i mentioned it in my first post. "1 seam for slags made on a semi-automatic machine". Semi-automatic marble machines like the ones used at Peltier for hand gathered marbles. Fully-automatic machines like Peltier's US1,927,650 made slags with two seams.

Have a great one Duffy.

I can find at least one cut line on every slag i own. Akro being the hardest to locate, and sometimes needing a high powered light just to find it. So should those be referred to as only the ends of the stream and not seams, like the WV swirls? That doesn't make good sense to me. The cutline on the slags does not resemble a rounded tongue or stream end, it's look exactly like a straight-line cut mark.

The major difference in my opinion, is the way the molten mass is sheared. No seams for WV swirls. 2 seams for machine-made slags (fully automatic machines). And 1 seam for slags made on semi-automatic machines.

Very slag-like appearance. The semi-opaque base seems to be the hardest to find, possibly some fully opaques out there too. Light will barely pass through the murkiness to see that the ribbons go all the way into the marble. Most are transparent based and some are translucent.

+1 prayer, get well soon.

Time for a new thread? Most hand gathered slags have irregular or circular patterns. But the two seamers are more striped. CAC and even Peltier's feathered slag, in essence, has surface striping from seam to seam. There is another two seamed Peltier slag-type marble that i like calling a "jewel", because the base glass reminds me of gem stones. It is a 6 ribbon NLR slag-type (slag-looking) marble, with ribbons that can be swirly or straight. Base glass seems to be of extra high quality and is almost always mis-ID'ed as CAC!

Great explanation for the end of the stream. And that just about answers my shear question too. So basically, the older swirls will have a thicker stream?

Thanks for the insight, makes the processes easier to visualize. I have also have quit the term "miller" for anything other than hand gathered. Gotta give Peltier his due.

Thank you for clarifying that Galen. I've been under the impression that those were cut marks. Marble King's "V" shaped shear sounds like US patent 1,993,235 for the Lawrence Glass Novelty Co. which is a separate mechanism and adaptable to the marble machine. Marble king did produce swirls at one time??? I wonder if these sheers could have been used elsewhere in WV??? This particular patent was submitted in 1933.

Interesting box in lot 92....

WV Swirls are difficult to I.D., especially for newer collectors. Are there any significant differences between the shear marks or shearing mechanisms used at the various WV swirl sites that may aid in identifying them? Or are there no differences at all? Were their mechanisms designed to keep shear marks as non-visible as possible? Any insight is greatly appreciated.

Does anyone have photos of these master bags with marbles? I was hoping it was the century of progress bag but the thread count is off and the year of submission is late. I've learned patents are not always what they seem, so was this exact bag even used at all?

I see what your saying Mike. And its good info. In comparing some of the old swirled up pelts to the feathered slags, i do see the wrap around pattern on the feathered slag that your speaking of. While the old swirled up pelts are piled up with internal swirling in a random-like fashion. Both marbles still exhibiting two cut lines, but the swirled up old pelt's cut lines being harder to spot. Do you think the feathered slags were made with the Peltier's following patent of vitreous-like objects submitted just a year later or most likely on the feb 1931 patent of agatized bodies? And are there any company inventory cues that can help with a date? Patent link: http://www.google.com/patents/US1865787 Patent link: http://www.google.com/patents/US1946879

Peltier's move from semi-automatic to nearly full automated machines was introduced publicly with US patent 1,927,650. Striating the glass was one of the most covered topics in the patent text. Do you believe it was used to make peltier's feathered slags? Why or why not? Patent link: Method of and device for making vitreous objects
