[pure-silver] Re: Red Filter..... rubylith

Hi, Thanks for the tip regarding the use of rubylith . I have 4 of those circular Kodak safelight that screw into a socket. I took the OC filter out, measured out 4 round filters on a sheet of rubylight, and presto, red safelights. I put the circular sheet on top of the OC filter and insert the filter.
It is dark, though, I have 15w bulbs in them. Would switching them out for 40w bulbs brighten things up a bit or is 40w too much???? I just so happen to have 4x40w bulbs. Still, cheaper than buying the red glass filters. What is their designation???? O_? 

Now to get more rubylith, have t make a filter for my 8x10 safelight.

Cheers,
Bogdan

Don't know the filter values but I would suggest that you cut some plain glass to size and then cover with rubylith which is red masking material used for filtering with lith films and line art processes. In the UK I bought some called AdMask which is sticky on one side. That should do it and its a cheap option. The rubylith will come in handy for other masking in the darkroom from time to time.
