Jeffery, You do realise that ammonia is a fogging agent, don't you. How did you ever manage to keep it from contaminating your unprocessed materials? When I was 20 I worked in a lab that did both photographic services and diazo printing, which developed in ammonia fumes. You couldn't move from the dyline area to another without a thorough hand scrubbing, lest all your subsequent work would be spoiled, and any contaminated chemistry would need to be ditched. Even just handling a finished dyeline print would contaminate your hands for other photographic processes. I wouldn't have any ammonia product in the same room as photographic film or paper.
