Hi again,

I spent the last two days coating/printing Cranes Platinotype (which I
commented about previously) and living with the imperfections in the
resulting prints. I have added a step to my working notes which suggests
that after cutting the paper to size, I should inspect the surface for
imperfections of any kind - including shiny spots that won't take the
sensitizer and also which won't take any sort of spotting color. Hopefully
my next batch will fare better - I found 20% rejects.

That being said, I must add that in the last two days, I have answered some
of my questions and have created some others. For example:

    How does outdated #! & #2 ferric oxalate affect the resulting print? I
have some that is 8 months old and that works on some prints and
    not on others.

    My work area has a fairly consistant RH of 65-72% - rain or shine. What
is optimum?

    How long after coating/drying is acceptable to leave the coated stock
unused and how should it be stored?

    I like the color and surface texture of the Cranes 90# cover (aka
Platinotype) - if I buy more am I apt to run into the same level of quality?
    Would someone recommend a substitute and a source for it?

Many thanks for listening,

Nick
