Maria,

If you want to have the "same contrast properties" as your potassium
dichromate solution, make an ammonium dichromate solution at the "same
strength". If you're using a saturated Pot. Di. solution and not sure
about it strength: ...should be around 10% - %13. Keeping and mixing is
no different from Pot. Di.

Regards,
Loris.
