Greeneyesgreenthumbs Posted May 21, 2021 Report Share Posted May 21, 2021 This one measures .74 its is out of round. Looks like a handmade made slag type I would love to know who made it. Gorgeous marble! Thanks Link to comment Share on other sites More sharing options...
Chad G. Posted May 21, 2021 Report Share Posted May 21, 2021 Machine made marble, sorry Danny no idea on maker !! Link to comment Share on other sites More sharing options...
Ric Posted May 21, 2021 Report Share Posted May 21, 2021 The white looks like batch glass, and based on size, my first guess would be Alley. It is a pretty one. Link to comment Share on other sites More sharing options...
Greeneyesgreenthumbs Posted May 22, 2021 Author Report Share Posted May 22, 2021 So....what causes a marble to become egg shaped or out of round when made from a machine? Link to comment Share on other sites More sharing options...
Chad G. Posted May 22, 2021 Report Share Posted May 22, 2021 A few pics of some machine made "manufacture defects" Eggs, pancakes, footballs, barbells, double ingots all happen between the shears & the end of the rollers. Ron explains it much better than me, I'll just post some pics. Hand mades also will always exhibit some form of a pontil !! Barbells, dug Heaton A few double ingot on either side with some footballs in the middle, more dug Heaton examples \ A bunch of footballs & pancakes, mostly Akro. All these marbles pictured were machine made & probably dug near te factory in a cull pile. Link to comment Share on other sites More sharing options...
Ric Posted May 22, 2021 Report Share Posted May 22, 2021 5 hours ago, Ric said: The white looks like batch glass, and based on size, my first guess would be Alley. If there is a lot of "feathering" on the underside of those white ribbons (like someone dragged a fine fork through the underside of the white striping glass) on the inside of the marble, it might be CAC, but 3/4" would be a much less common size for CAC than Alley, and CAC didn't make anywhere near the numbers Alley made either, hence my hesitation to go there. Either way, the shape suggests it's probably dug. Link to comment Share on other sites More sharing options...
wvrons Posted May 22, 2021 Report Share Posted May 22, 2021 When a hot glass glob hits the marble machine rolls, the rolls job is to make it round. The glob has to spin in all different directions on its own axis in each and every groove of the rolls. If it is to large or to small it will not fit the groove correct and not spin correct. If the glass temperature is to cold or to hot the glob will not spin correct. If the speed of the rolls is to slow or to fast the glob will not spin correct. If the rolls gets a build up of glass the glob will not spin correct. All this above and more affect the shape and pattern of the finished marble. They are non standard production which happened often and routinely with every machine made marble company. Most were sorted and discarded, but not possible to sort out every error.

wvrons Posted May 22, 2021 Report Share Posted May 22, 2021 The original marble in question is Alley. The hot glass glob was to large for the marble machine roll groove size. So it is out of round. Link to comment Share on other sites More sharing options...
Chad G. Posted May 22, 2021 Report Share Posted May 22, 2021 Phew !! Glad you showed "Ron" a lot better at explaining manufacture errors than me "Thanks" Link to comment Share on other sites More sharing options...
William Posted May 22, 2021 Report Share Posted May 22, 2021 Yes, his explanations of the production process surrounding marbles is indeed valuable resource...When I first started collecting I always thought the "out of rounds" were just cheaply made moderns. Ron's clarity on that, when he explained it before in a different thread, opened my eyes on these errors so now I always take a second look at them. 😊 Wish I would have had someone like Ron around all those years when I was collecting football cards! I can only imagine all the errors I missed 😳 Link to comment Share on other sites More sharing options...
Chad G. Posted May 22, 2021 Report Share Posted May 22, 2021 "Yes indeed" wish we all could have actually worked manufacturing marbles like Ron did. Right place, right time, great people, when you love what you're doing not considered work to me anymore but a pleasure, what a lucky dog !! If I didn't love the Pacific Northwest so much I might have moved a little closer to the action ?? Link to comment Share on other sites More sharing options...
