IS this a Jabo? looks like a wine glass .74

thanks.  Does it have a name?

 

[Fire1981]

I think that’s up to you. 👍

[Fire1981]

Platypus ? 

[Fire1981]

Beak ?

Or Vitro? Pinched seams like that on a JABO would be highly unusual.

[Fire1981]

DuLite or TriLite ? 

[Fire1981]

What color is the base glass ? 

[Fire1981]

I keep seeing Vitro Purple/Amber in the dark ribbon in the second picture.

Jabo Buttcrack or the Vitro “V” ?

With those seams in the last pic?

Strange marble.

The last photo might throw off a bit, but especially the first one tells me Jabo

I just don't see anything convincing enough to move me away from the odds on this one.

The first picture is the typical trade mark butt crack. The third picture is the opposite side of the butt crack fold. This all happens because of the short glass stream from the furnace to the shear. Short stream makes faster speed. The last picture is both cut marks close together, because of the fast speed the hot glass glob never got to fold over completely into itself before it was sheared by the second cut. 

 A translucent cullet white base. The two added colors were orange and brown or maybe a purple. Those colors are in a straight line down the side of the elongated hot glass glob as it falls to the shear. The short stream does not give it time to twist. The shear cuts going across and fast going back across again. The glob never gets to twist or fold and the cut lines end up close together. The color stripes end in a big U shape. If it gets pinched or folded together tight you get the Jabo butt crack.  

This happened a lot with Jabo classics.  This also happens when they change the speed of the cutter, or the speed and amount of flow from the furnace to the shear.  If the operator notices these two cut lines close together he will change things to correct it. Because it will lead to more and bigger problems.   

Jabo classics end with more U and butt crack patterns than V's like Vitro's can.  But even Akro has lots of V patterns.  The V pattern is also from a short glass stream to the shear. Some people believed that Vitro made the V on purpose to represent Vitro. That is not true. I ask two Vitro plant managers and a few workers about the Vitro V. They did not do it intentional to represent Vitro in any way.   If it ends up as a U or a V can depend on the exact type of shear and or the spacing between the holes of the shear blade. Less space between the holes and you get more of a V.  Plus shear speed can change it from a U to a V or closed butt crack.  Most of the shears at Jabo were old original late 1930's-1950's Vitro shears mounted on old Vitro marble machines.

Thanks for this, Ron!

No problem. All companies had some marbles with the two cut lines close together or near each other, instead of on opposite sides of the marble. Nice Peltier examples in Sami's Peltier book page 48 top left, page 50 top right, page 53 top left, page 54 bottom left, page 68 top left, page 148 top left, and more. All companies had some of these, but with swirls WV or Peltier, it is not often seen because most swirls fold the cut lines inside and not seen.  It happens from glass stream flow size, or speed and shear speed.  Especially when things change from standard operation. When problems happen which was often.  Collectors like errors, Ying Yang pattern, Ram's head, metallic's, burnt colors, odd shapes, aventurine by chemical reactions, double ingots, etc. A long list of error type marbles because there were millions or billions of them. Most were discarded but many made it to collectors today. Not special made or experimental, just non standard production.
