lstmmrbls Posted March 30, 2015 Report Share Posted March 30, 2015 Have not heard that term used for a while. Here is a classic CAC R&T Link to comment Share on other sites More sharing options...

IowaMarble Posted March 30, 2015 Report Share Posted March 30, 2015 So, the "road" is running up and down on the bottom half of the marble and the "tunnel" is the ribbons of color that makes an arch on the upper half of the marble? Thanks for posting this by the way, I had been wondering what was meant by the term. Link to comment Share on other sites More sharing options...

ann Posted March 31, 2015 Report Share Posted March 31, 2015 Nice. I've only heard the road-and-tunnel phrase used to describe Ravenswoods (a ribbon "diving into" the marble). Looks more apt here! Link to comment Share on other sites More sharing options...

chris94 Posted April 1, 2015 Report Share Posted April 1, 2015 a road and tunnel pattern indicates a hand gathered marble. It also indicates the gather is mixed "on the stick" or ponty rather than in a pot like the 9 pattern. You also may be able to tell whether the gathering boy was right or left handed by the direction the road approaches the tunnel. chris robinson Link to comment Share on other sites More sharing options...
Shamrock Marbles Posted April 1, 2015 Report Share Posted April 1, 2015 Chris, Great to see you! See you have the "94" in your screen name. I can't find my R&T pamphlet, so can you clarify the Road & Tunnel dates for me? Also, was this a common term in the day or did you originate the term and T.M. on your pamphlet? Sincerely, John McCormick "Shamrock Marbles" P.S. You must be ambidextrous, since I samples from you coming from either direction. Link to comment Share on other sites More sharing options...

winnie Posted April 1, 2015 Report Share Posted April 1, 2015 interesting thread!!! Here's another German road and tunnel it's 15/16.Think they were made in the same way as the CAC's. Sure want to know more about them,just as Ann and Mon,I'm sitting here,all ears. Link to comment Share on other sites More sharing options...
chris94 Posted April 1, 2015 Report Share Posted April 1, 2015 The road and tunnels in Johns post were done in the early 1990's. I can't explain exactly how the pattern is created but know my marbles were made by picking up different colored pieces of glass and heating them in a glory hole while spinning the ponty. CAC marbles may have been gathered from a pot but the ponty spun before gobs were cut off onto a rounding machine. The term road and tunnel was used in a pamphlet describing my marbles just because that's what it looked like to me. Link to comment Share on other sites More sharing options...
chris94 Posted April 1, 2015 Report Share Posted April 1, 2015 I speculate that M.F. Christensen "9" slags were gathered from a pot that was stirred in one direction. The gather would have to be hot enough to drip off the ponty onto the roller without any additional spinning of the ponty thereby retaining the 9 pattern. This would explain the many examples with tails created by dripping very hot glass. Link to comment Share on other sites More sharing options...
chris94 Posted April 1, 2015 Report Share Posted April 1, 2015 the road and tunnel pattern may also have been caused strictly by the act of cutting the gob off the ponty with a shears. A lot more experimenting would maybe clarify these questions. Link to comment Share on other sites More sharing options...
ann Posted April 1, 2015 Report Share Posted April 1, 2015 I can't explain exactly how the pattern is created but know my marbles were made by picking up different colored pieces of glass and heating them in a glory hole while spinning the ponty. So, by picking up different colored pieces of glass (and spinning and heating etc.) you were, in effect, creating the layers of colors we can see?

chris94 Posted April 1, 2015 Report Share Posted April 1, 2015 yes the ponty is spun slowly enough that gravity will pull the outer edge of the gather around. Link to comment Share on other sites More sharing options...

lstmmrbls Posted April 2, 2015 Author Report Share Posted April 2, 2015 At this point in time I do not think the CAC R&Ts are handgathered at all. They are a 2 seam marble with a weird twist and a fold but thats all it is IMO. Chris Rs marbles were a neat representation but I never thought they were a real accurate representation oa real good CAC R&T. Could be cause I didn't like the repros at that time, and really still don't Link to comment Share on other sites More sharing options...
chris94 Posted April 2, 2015 Report Share Posted April 2, 2015 Hansel, I can still make R +T slags in fact John McCormick and I made a batch in 2007 along with other pattern slag and oxblood's. . Link to comment Share on other sites More sharing options...
