Has anyone here done much work with Ziatypes from B&S? Reason I ask, is I had one of the small kits that I did some work with last summer, then got caught up with several other things and yesterday, decided to pull it out a try some more printing. The Lithium Palladium Sol. (No. 3) had turned a dark brown (which may the color it was when it arrived, do not remember) and the Ammonium Ferric Oxalate Sol. (No. 1) was light green - do not remember what it looked like either.

Went ahead a mixed some up and coated some paper (cream to light brown surface) and exposed a negative - took maybe 5 minutes in Texas sun.

Any thoughts?
