This isn't just Arches Platine, and not just from oxalic, or whatever.
Some papers get translucent spots being sized for gelatin & possibly
reappear in development. The reason I can't say which, is because -- at
least for gum -- the spots are NOT detectable in the dry paper, or in the
print. Of course there might be some residual effect in other media.
But... odds are there won't be. So go figure.
