OK, I won't tell if you won't! Besides, I didn't know there was a higher
power... (that is a joke, although I try to avoid inernet "smilies" at all
times).

Yes, I think you are exaggerating the effects. Surely in their powdered or
liquid states, contact with or inhalation of oxalates, dichromates and heavy
metal solutions/powders should be minimized as much as possible. My rationale
for touching the dry, coated paper is this: I don't touch the paper until it
looks dry, or when I expect it will be dry based on experience (15 to 30
minutes after the first coat and an hour after the second), and then only
briefly. I am hard pressed to believe this is giving me any significant
chemical exposure to be concerned about. Of course, that is just my opinion,
and I may be wrong. I imagine breathing the air in any metropolitan area is a
much greater risk to one's long-term health. Plus, the paper feels good!
