Comments:  Uses CIP CLEAR as base. Not bad. A little dark and too blue/green. Try 0.5 Cobalt,  4.0 Copper, and 1.0 Chrome Ox.
TESTED 10/31/2011: Good color. Blue/green. More blue where thick. Some runs where thick. Try more silica. Try more Copper and no Cobalt.
TESTED 11/8/11: Still runs. Less Frit and more EPK
More Copper and Rutile.
TESTED1-30-12   GC-3 added back in 0.5 Cob Carb.
Still apple green and gray. Min runs. Very apple green over 32 with interesting streaking. Less Zirco and less Rutile.
TESTED 2/10/12: Nice Blue Green. Slightly transparent.  Best if medium thick w/ good movement. Runs if thick w/ lots of movement. Med/Thick on buff. Nice dapples in field.
