Been chatting with Ralph Lucht and he postulated something I don't remember hearing before.
Proposal:
Guineas weren't actually made at Christensen Agate Co. They were made by Arnold Fiedler at Cambridge Glass from canes and rounded on modified MF Christensen machines. Then they were sold in limited quantities through Christensen Agate.
Ralph has spoken with people relatively close to the source about this.
Seems a touchy subject. Many are like me with no well-formed opinions about them and watch from the sidelines. Those willing to get into the discussion seem to have strong opinions and positions are quickly fortified with no movement. And Guineas remain mysterious.
So, I _am_ intrigued by the idea that Guineas are actually Fiedler Cambridge marbles sort of jobbered through Christensen Agate rather than made there. So I am starting a new discussion on it!
Possibly an Akro patch. The colors aren't standing out well enough for me to be able to get a clear picture of the structure but from what I can see the pattern is good for Akro.
However, not a Lemonade. A Lemonade has a moss agate base and is a swirl or a cork, not a patch.
The seams, the colors, the orientation of the color ribbons ... and more of a generic UV, not particularly an Akro UV. I have UV in my obvious Masters.
Those are reasons for my Master vote.
Your enthusiasm has been such a delight. You've made me want to go to Standing Stone ... or drop in at whatever park you're working at if I ever find myself in Tennessee.
The glass doesn't look slag-like to me ... so I'm not sure what I wanted to guess the Peltier Co. meant it to be.
And obviously whether it is Pelt or not is still up for debate.
Ha!
I have taken screenshots and blown them up to try to figure out marbles in other shows -- Little Lord Fauntleroy for one -- but I didn't know there were any in To Kill a Mockingbird.
