Hi, Joe -

I read an article - I've forgotten where now - recommending developing TMax
at really high temperatures -over 100 degrees, so I knew it wouldn't cause
problems.  Modern films are pretty durable.  They don't need hardeners and
don't usually give any problems with reticulation.  To demonstrate
reticulation to a class once I had to use really hot water and then ice
cubes to have any effect.  The charts for Kodak XTol go to 82 degrees.  I
believe that is the highest they give, but you can look at the chart and
the increase is mathematical so it's pretty easy to figure out.  I used to
go to the trouble of putting ice cubes in my Jobo but no more - it's not
necessary!  Take a few experimental rolls and try it.

Leically,

Tina
