Would it be too much to ask if you could be plain spoken here?

I don't think you mean potatos or chocolate. So again what the hey do
you mean by ... a paper with no "B" pot. chol. in it.

I wondered what that meant too.

The jargon on platinum printing is for the light sensitive iron solution to
be referred to as'Solution A', the contrast control solution of potassium
chlorate is 'Solution B' and the platinum solution is 'Solution C'

If 'non B paper' does mean paper that has been coated with pt/pd sensitiser
that does not include potassium chlorate as a contrast control to suit a
particular negative, then the negative for that paper is the right negative
for pt/pd printing.

Get the negative right and there will be no need to contaminate platinum or
palladium prints with potassium chlorate which has more the effect of
degrading the image than improving the contrast.

Did the VP think that the plural of potato was 'potatos' or 'potatoes' ?
