I think I'm going down to the thrift store next week to find me a proper filter holder :)

This list is so funny sometimes. We run into the same problems so much and I really enjoy seeing what other people come up with. I was immediately offended by the slowness of the filtering too. I have this huge roll of copper wire in the garage. I made a conical coil by making severals wraps of wire around the outside of my funnel. Then I put it inside the funnel. There was a little extra sticking out which I bent over the lip of the funnel to hold it in place. creats airspace just like you said. Amazing how much trouble I go to to avoid having to go buy something. Even for a dollar ;)

Subject: Coffee filters

Just found another good reason to drink coffee. My negatives have had a lot
more junk in them than usual, and I've started thinking it was coming from
the fixer. So I poured the fixer through a coffee filter and was surprised
by what I found. There were those tiny bits of fiber and flecks of
who-knows-what, and just little particles of dirt that I've been finding on
my film. I think I'll be doing this more often. 



jun2605 from Lloyd Erlick,

It's a really good idea for selenium toner, too. I've pretty much stopped
discarding my selenium; I just keep topping it up when it runs low. Frequent
filtering helps keep it clear.

To make the solution pass through the filter relatively quickly, it's
important
to have air *behind* ("under") the filter. I have one of those solid mesh
'permanent' coffee filters (not the gold-plated kind! There's always one
available at the Goodwill for pennies) and I put my paper filter (much finer
filtering than the mesh) inside it, and the whole thing goes into an ordinary
funnel. I found if I put the paper filter in the funnel directly, it went
through extremely slowly, because the paper sticks to the funnel. I tried one
of the filter-holding-funnels made for the purpose (a genuine Melitta with
ribs
to hold up the filter ...) but it was only marginally faster.

regards,
--le

Be careful with copper and photo chemicals. Some produce unwanted and sometimes dangerous results. I seem to recall someone getting very sick when trying to develop photos that were exposed on liquid emulsions that had been coated on copper clad boards. I am pretty sure Ilford was involved in that issue.

I can't search on the archives but the details should be either here or on the old pure silver archives.
