Description: For your consideration, from the 8-17-2010 JABO, Inc. 3/4" JOKER 'Orbits' contract run, a very nice 4-color drizzle swirl. It appears to be glossy smooth, mint condition in hand. I saw a very tiny sparkle, but under 10x magnification, I found it to be a subsurface bubble. I was also able to spot a couple micro touch points. There is a couple very small dimple lines where the tail of the drizzle did not quite smooth over. Not bad at all. No other cold roll defects, no bruises, moons, or other visible issues. It measures 25/32". Over 3/4" spec. size. These drizzle swirl specimens are very rare. How do they occur? Similar to a well seasoned cast iron skillet that is beneficial for non-stick performance, the marble machine diverter cups/funnels/shoots must also be non-stick. Even more so than the skillet, where prolonged extreme heat can burn out the seasoning, the marble machinery is subject to much higher levels. The old Vitro Agate Co. 3/4" machine JABO, Inc. purchased and utilized for these contract runs would occasionally experience some sticking. Most of the molten gob would proceed to the rollers while the point of glass stuck to the diverter, anchored a filament of stretched glass that was created as the gob fell to the rollers. In a matter of a split second, to maybe two seconds, the filament would snap off, to then be reeled in by the spinning marble. Many variations of drizzle pattern types are seen, due to the amount of stick, timing temperatures and activity of the gob as it settled onto the rollers. This occurrence was dealt with under the watchful eye of the machine operators to avoid damaging marbles, as the gobs would sometimes hop around, often joining other gobs, creating an out of control domino effect, ruining everything coming down the line. The removal of these culprits makes the drizzle swirl type even more rare. The cure was to lubricate the cup with a greasy swab. Some early post-swab marbles exhibit a little baked on grease stain before the excess wore away. I offer combined shipping. Hold off on payment until you're finished bidding/buying my items. If I've figured this system out, when you attempt to pay, all purchases should combine for an invoice that charges the single marble shipping rate. If this is not the case, request an invoice. If all fails and you pay multiple shipping charges, I will refund the balance of the actual charge incurred by me. Thanks for looking.
