Re: material for tissue in dry climates

hello Claude,

I will echo Sandy's comments -- the glycerin will help (additional sugar
will also help if you don't have the glycerin)

And living in a humid climate I have ruined a couple negatives by having
too much glycerin in the mix. (I just wave the glycerin bottle over the mix
now to give it a bit of a scare.) It was an interesting experience trying
to seperate an 11x14 neg stuck to the tissue after exposing -- I accidently
ripped the negative in half trying to pull the two apart. It was during an
in-class demo...quite dramatic! Fortunately, I had taken two negs of the
same scene and had ruined the lesser of the two.

For the tissue support I use used litho film that our students toss out --
the .004" stuff. I found the .007" stuff too stiff (hard to maintain good
contact with the negative during exposure.) I have used the same pieces of
litho film 20+ times. Nice to be able to reuse material instead of buying
and tossing it out after one use. Freestyle sells litho film in all sizes
if you can't find used (for 8x10 negs, you can get litho film in 8.5"x11"
for 100 shts for $53 -- and that should last you a lifetime of carbon
printing...your results might differ.)

I get a minimum amount of curl with the litho film, but a pourous support
does have its advantages (eg. tissue dries faster).

Have fun!

Vaughn
