I have however come across warnings against fluorescents in "the
literature," but wonder if the warners ever tried it. As I've
probably mentioned, when I was teaching "non-silver," the classroom
(a repurposed chem lab) was lit by several banks of fluorescent
lights set in a fairly low ceiling.
But I gather that some folks really do coat by safelight -- and, if
memory serves, some how-to sources advise that. (Is that possible? YIKES!)
I coat and/or sensitize gelatin-based dichromated processes by red
(lithographic) safelight, after proving to my satisfaction that the
gelatin-dichromate processes can easily be degraded by fogging even
under bug lights or low-wattage incandescents -- but, as I've said
before, I don't use gum, and what is necessary for dichromated
gelatin is not necessarily required for dichromated gum.
Best regards,
etienne
