to be on the safe side, i have ordered new ferric ox. and pot. ox. i also bought
new trays. some one made a comment about new ferric ox. and old palladium. i was
under the impression that platinum and palladium had no shelf life problem. am i
wrong in this assumption. if so i will also purchase new plat. and palladium.
also i had started mixing cessium palladim with standard palladium and platinum.
could this have been a cause of my problems. i had never done this in the past.
i do use super actinic bulbs. they are about 2 years old everything else is the
same.
