Jess, You must have been a lot smarter than I was. On my first
try, it never occurred to me that I shouldn’t quinch after
casting. I was using a cz the color of which I didn’t like.
Well, quinching did it a favor. Cracks, crinkles, round bumps
all under the surface and a mellow color to boot. Now its a ring
holding a stone with charaacter. Since the first try I’ve had
mixed results. Are you casters using prong settings or bezels?
On one of my bezel set stones, it looked perfect until I began
cleaning it up (after the flask had cooled on its own).
