[pure-silver] KBT fog - was Re: KRST


I found the odor of hydrogen sulfide very hard to bear when I stupidly used
the brown toner in my darkroom. That is an outdoor activity. It'll fog
photosensitive materials, too, so doing it in my darkroom was dumb.
So, using KBT in a darkroom (without adequate ventilation) could conceivably fog unexposed paper? Is the result a general fog and loss of contrast? 

I assume that the amount of KBT in the air would have to be substantial.....
