I just received and used a new batch of Pyrocat MC in glycol (from PF). I did a direct comparison to HD with 2 sheets of 4x5 FP4, same shot, same dilution and time, etc. Differences will have to be seen after printing, very close, as promised on other threads.
One thing that suprised me, though - the color of the MC Part A was very dark, like old Rodinal, or coffee. This stuff is less than a week old.
Part A of HD (in water) is very light amber, even after a year in small bottles.
Is this normal for MC?
