dark slide material

I have a few ULF holders in various sizes that need new darkslides. I'd
like to try making them myself and I'm wondering if anyone has actually
made them out of garolite (sp?) or maybe sheet aluminum? Might other
materials be appropriate?

TIA for any info.

Dark slides have been made of several materials. At one
time hard rubber (Ebonite) was used. Metal slides have also
been used and are quite satisfactory. Aluminum or brass
should do. Darkslides for Riteway and Kodak holders are
coded for IR opaqueness. Older, non-opaque slides are coded
with three bumps on the silver side, IR opaque slides have
five bumps.

Thanks for that info; I've long wondered about those bumps, and what meaning
they might have. (The slides I looked have five bumps, so I'll sleep easier at
night.)

imagined, some new and unspeakable form of sexual debauchery practised
by young persons of dubious morality, but a way of providing news
articles to the cybernetic publishing moguls of the World Wide Wait so
they can fill the airwaves with even more useless drivel.

Richard,
Thank you for dropping that pearl of information...I had always heard that
there were IR-opaque slides, now I know how to identify them!
Thank you!
