Andrew had it over "exposed" film and paper. I assume with this he meant "exposed and developed".
In this case you need to bleach and fix as I stated above.
Andrew had it over "exposed" film and paper. I assume with this he meant "exposed and developed".You need to fixit first to get thesilver out off the emulsion; then, process as above but frankly this is all a bit OTT for me.
What I have been doing is taking the spent hypo solution and added spent developer, put it in bottles and label it and take it to the hazardous material recycling near me. Of course there in no profit in it for me, but I feel that I am doing the right thing for the environment and recycling silver.
That's cool...what did you photograph?
Over all the years.. probably thousands of petri dish of bacteria and fungus cultures.. 'diseased plant materials, Polyacrylamide 'gels' (even published a paper on the 'how-to' photograph 'unstained' gels using 'cross polarized' transmitted light in the
Journal of Biological Photography (and I'm still a member of that I'd have to find 'my copy' to give you the issue number and 'date' I'll try and find 'my' copy the pages numbers etc. Or.. might you prefer a 'scan' of the pages?
And I'm not doubting you, I did terrible in chemistry despite my biological schooling. I've seen black silver deposits on bottles of used fixer and blixer I had laying around. I'm not sure why it happened sometimes and not others.

Do they recycle it or incinerate it? Aren't there any photo labs in SOCAL that will take it (the fix, not the developer)? I live in nowheresville and there are still photo labs that will take my used fixer.
All I can offer is a suggestion that you 'Try it for yourself'.. i have been receiving some 'you are full of 'sh*t' replies'
I've been 'working' under the dark-cloth for some 65+ years.. but have indicated that "I still do NOT know all there is to know about either 'making' good Photographs or the 'best way to accomplish that which you feel you 'need' to do to 'get a 'something done' done.
I'm somewhat more than surprised to find that there are still 'some' contributors to Photrio who seem to rely on 'my way is ALWAYS
BETTER than your your way.
It coming to the point where I am seriously thinking about 'walking away' from Photrio.com even though I 'think' I may have more knowledge (gained from past experience and formal 'education') than a significant number of posters who do not have the practical experience (and knowledge) to 'diss' some of the 'how-best to achieve the better 'results' that I have submitted over my 'time' on the forum.
I found my silver recovery by 'accident' (and contacted Dr. Mowery) who then indicated it WAS the cheapest and easiest method of
(but NOT the fastest means of recovering silver from used fixer.

[All that being 'said'... I believe I may have more 'practical experience' (and 'formal' education) than a significant percentage of other posters. (and I do have the 'letters' (after my 'name) on my 'business' card than the majority of those who 'post' on Photrio.
and I'm becoming somewhat 'frustrated' by the "You are full off 'sh*t" Nay-sayers who do NOT have the number of years of 'practical experience' under their belts as I have.
Its almost enough for me to say "Good bye"

Please be reasonable. I do not see any of such.i have been receiving some 'you are full of 'sh*t' replies'
I'm not sure why you have directed such a venomous reply toward me. Perhaps that wasn't your intent. I neither doubted you nor said anything intended to cause doubt in what you said, in fact I related experience that I thought lent support to your method.
Wayne
My sincere apologies....
My response was NOT directed at You..

KenS: I for one saved your post, printed it out and will be using it in the future. I am an avid recycler/saver and appreciate the information.
KenS
Sorry for the raft of questions but I figure you are a scientist / science person and you might know the answers/ have them written down somewhere or PE ( or some other EK. photochemist you know ) might have told you ...
- Have you determined how much silver remains in solution after you do your recovery method ( using something like a STF50 or industry standard test, or environmental lab ) ?
-Have you "washed" your spent fixer more than once to determine if you can extract more silver out of it ?

I may have missed out the fact that I do syphon off 'about' 40% of the total volume after I can see the few inches of the 'black precipitate.. mostly to 'make room for more used fixer that will be followed by 'more used but not dead developer.
As a 'rule' it may take me a few weeks to 'replenish the volume of used fixer (followed by some used.. but not 'dead developer
Its almost like 'topping up the last 1/3 of the coffee in your mug and adding a little more 'cream/cream and some more brown sugar.
I don't wait until I have a (excuse my pun) a 'fixed volume' unless I 'need the space' 'available to add more of both used chemical solutions. (but I Never 'throw out' any left overs.. they are 'saved and 'lebled' as to either U-Dev or U-Fix. for the next
"Make The Black Silver Appear" session a few months later (after I have washed the 'recovered silver.. dried it.. and poured into a 'ready for melting' container)
I have to admit that there have been a few times (after a somewhat longer darkroom session.. and I'm in need a 'sleep' break
so just I pour it into a smaller 'brown glass' container that is then 'capped' and labeled as to the contents.
My Scots heritage HATES to see 'money' going down the drain.

Ken,
I expect the rude responses you got may have originated, in whole or in part, from a person or persons I have on ignore, because I couldn't figure out what rudeness you were talking about!.
You may wish to both report the rude responses to the moderators and put the source on "Ignore".

Matt,
I may be "Old and Grey" but I'm willing to bet that I have more years of experience (somewhere in the region of 65+ years) than many of those who seem to disagree with the means by which I recover the silver from used fixer. Many of those years were
spent as a "Professional" in the employ of Agriculture Canada's Research Branch. I am a "Board Certified" Registered Bilological Photographer' was elected A Fellow of the Biological Photographic Association for my contribution in the "Biological Sciences" and earned my BFA degree after my early 'retirement' thanks to Agriculture Canada's 'eastern' Agriculture Canada's Research Center was 'closed down (the PM 'sold the land' on which it stood.. and needed to transfer as many of the scientific staff westward to S. Alberta and thus needing the floor space I occupied.. just at the 'time' when digital capture was becoming easier (and less expensive). My daughter then 'challenged me to 'earn my BFA' degree at the nearby University.. so I did... and graduated at the ripe old age of 74 years, with a 'good' GPA (I believe it was 4.3 (I was also elected.As a Fellow of the Biological Photographic Association (now known as Biocomm.org) for my 'Contribution' of imaging in the Biological Sciences
In all reality... I believe I may have a 'wider and more extensive experience (and background) in the 'field' of photography than most of those who contribute images (and 'ideas') to the Photrio website. At the ripe old age of 80 I am quite willing (and able) to admit that I still don't "know enough" about the art and the required "Craft" of Photography.
Should you be interested... I have a substantial number of my 'post retirement' artistic endeavours on the 5x4.co.uk web site
as "KenS. in a number of the 'subjects (you MUST to sign in with your 'real' name, your e-mail and a 'password' as a 'visitor')..its for 'security purposes only.
I believe Donald Qualls has recently 'joined up' and has...or will be (or has been) posting some of his images.
