Intensification film crystals-mercuric chloride

[Tala Brandeis <brandeis@xxxxxxxxxxx>]

Realizing this is not an IR specific question, given the level of
knowledge on this list I thought it might be a place to obtain an
answer...

I’ve got some very thin 35mm Tech Pan Film exposed at EI 200, developed
in C-76 for five minutes and after some struggle attempting to lith
print, I decided to intensify the negatives in Mercuric Chloride for 2
minutes.  After intensification the negatives have red-orange crystals
covering them.  On extreme enlargement to crop 1/4th of the image at 
11 X 9 (image size) the crystals appear on the print as white spots in 
the black areas of the print, a veritable snow storm of "dust."  A friend
suggests the formation of the crystals may be a result of differences in
temperature in the intensifier solution and the wash water.  Before I
work that possibility by printing the image (and 20 others) non-lith 6X9 
and copying the image to new film, or clearing the film and intensifying 
the image one more time, I was hoping someone might be willing to 
offer thoughts, observations and recommendations. 

Thank you,
