Kosher Salt ? Interesting.
Lox anyone :-)

You can use Lox on your prints but they will attract
cats.

nov1804 from Lloyd Erlick,

There is no need for a darkroom to have "fumes". There
are darkroom products sold that smell badly, but even
these are unnecessary. It is easy to do all ordinary
black and white darkroom procedures free of odor.

It is also easy to do all normal processing with zero
chemical-skin contact.

Danger of fire in the darkroom is always an issue in
the sense that it is always something to keep in mind
in normal life. But normal darkroom materials are no
special fire hazard. Whether you're working in the
kitchen or the darkroom, safe practice is a must.

I have placed articles about these matters on my
website, under the 'technical' heading in the table of
contents.

regards,

No, I have another room (besides the bathroom) I was thinking of
converting into a darkroom eventually, but there's a water heater in
there. So my concern is with the pilot light. I doubt the fumes
would be concentrated enough even if they are flamable as I'll be
venting anyway.

What
about flamibility?

Are you trolling?

Pilot lights can be _very_ bright if they go to a
full burn. I'd say fog. I'd move the water heater
frame around it.

The heater is actually in a closet, so it won't be too hard to mask any
light coming from it. I just don't want to end up blowing myself up. :P

Oh... one more thing... and why can't I buy indicator stop-bath
online?

Who cares? Use vinegar, or Kosher salt.

Kosher salt? You're joking right?

I've heard of using vinegar... also citric acid from a grocery store.
Seems pointless though as stop bath is so cheap. The only reason I
would use anything "home-made" would be to get rid of odor.

It's not cheap if you have to order glacial acetic acid,
which is what a lot of us prefer and then dilute to 1-2%
stop bath. Hazardous shipping charges apply.

White distilled Vinegar = a 5% solution of glacial acetic
acid. Odor is the same.

Typical film/print chemicals are not flammable.
But probably a good idea to seal it off from
the room.

I'd use citric acid for oder problems.
