Cyanohighlights and brown bottles

I recently promised that my next post would be on-topic, and I'm a man of
my word. I have a couple of questions that I can't seem to find answered
in Keepers of Light or in a quick search of the archives.

In my cyanotypes, I notice that very dark areas of the print often create
a halo effect in adjacent highlight areas. For instance, the shadow of a
head will have a paper-white halo if that shadow is against a light wall.
So far, I like the effect and thus am willing to take credit for it, at
least to the uninformed, but being a picky photographer type, I'd like to
know if I can control it.

Also, I've acquired some small amber dropper bottles, the kind used by
pharmacists. They are not completely opaque, so I assume I shouldn't store
light sensitive solutions in them. Am I correct?

Finally, as a small digression, I offer today's selection from my desk
calendar of silly quotes. I thought list members might find it amusing and
apropos to recent events. From an 1870 Nebraska newspaper editorial: "The
apple of discord is now fairly in our midst, and if not nipped in the bud
it will burst forth in a conflagration which will deluge society in an
earthquake of bloody apprehension."

Best wishes to all,
Ron Connelly
