Czs and alloy

Hi Was wondering if you have any on setting czs in alloy.
(Setting the czs in wax and casting them.) We successfully set
diamonds in wax and also have set them in sterling but we are having
trouble in alloy.Some of the czs turn yellow and seem to have some
kind of burned look inside of them and also some are fracturing where
the metal meets the gold. Any would be appreciated.
Looking forward to hearing from you Mona Connoy Production manager
Kirchner Corporation Minneapolis, Minnesota email @Mona_Connoy

mona, at jewelmont, we used to hand set the cz samples if memory
serves, the alloy temp was too hot for DIW. hope things in mn are
well.
